DER Electric serves Bethlehem and the surrounding Northampton County area with residential and commercial electrical work you can count on. Whether you need a same-day repair or a full panel upgrade, we show up ready to work. Flickering lights fixed. Dead outlets revived. Power back on.
We are available for same-day service and after-hours emergencies, because electrical problems do not wait for a convenient time. Homeowners, landlords, property managers, and business owners across the Lehigh Valley call us when they need the job done right. Call (484) 916-4289 for a quote.
Whether this is your first repair or your tenth, you deserve a straight diagnosis and a clean fix. We handle the full range of everyday electrical problems for homes and businesses in Bethlehem: flickering lights, dead outlets, tripping breakers, failed switches, and anything else that tells you something is wrong with your wiring. Our electricians dig into the root cause, not just the symptom that got your attention.
Modern repair work also means keeping your home up to current safety standards. GFCI and AFCI protection are part of that picture, and we install or replace those devices when the work calls for it. You get the wiring done right the first time, and you do not have to wonder whether the fix will hold.
Flickering lights and outlets that stop working are among the most common calls we get. Loose connections, overloaded circuits, and aging wiring are the usual causes. A service call starts with a thorough look at the affected circuit, the connections at the device, and the panel. Once we find the source, we fix it properly and test everything before we leave.
A breaker that trips once after a heavy load is normal. A breaker that trips repeatedly is telling you something. It may be an overloaded circuit, a failing breaker, or a sign that the panel itself needs attention. We handle breaker repair and replacement, circuit troubleshooting, and the deeper panel evaluation when the situation calls for it.
Outlet and switch problems range from a single dead receptacle to a whole circuit that needs to be brought up to code. We install and replace standard outlets, GFCI outlets, and switches of all types. Every outlet job includes proper grounding and bonding so the work meets current code and your home stays safe. We'll have your outlets working again in no time.
Homes and businesses grow. The electrical panel that was adequate ten or twenty years ago may not be keeping up today. We handle 100-amp and 200-amp panel upgrades, main panel replacement, fuse box replacement, and service-entrance work for properties that need a full service upgrade. Load calculations are part of the process so the new panel is sized correctly for your actual demand.
Older panels are often the hidden reason behind repeated breaker trips and lights that dim when an appliance kicks on. If you are chasing those symptoms, the panel deserves a look. We give you straight answers about your panel and wiring, no surprises, and a clear recommendation before any work begins. Call and we'll get the current flowing right.
Some homes need a full rewire. Others just need one outlet fixed. We handle both ends of that spectrum and everything between. Whole-home rewiring and targeted rewiring of older sections of a house are jobs we take on regularly, particularly in Northampton County where the housing stock runs old and the original wiring has been in the walls for decades. Updated wiring matters for safety and for satisfying insurance requirements.
Dedicated circuits are another common need. Dryer outlets, range outlets, kitchen circuits, laundry circuits, and circuits for large appliances all require their own dedicated run from the panel. Where a home needs more capacity than the main panel can provide, we install subpanels to handle the additional load. We treat your home and its wiring the way we would our own, and we leave the work clean and code-compliant.
Good lighting changes how a space feels and functions. Inside, we install recessed lighting, LED fixtures, ceiling lights, pendants, chandeliers, and ceiling fans. Whether you are updating a single room or reworking the lighting throughout a house, we handle the wiring and the fixture installation together.
Outside, the work includes security lighting, landscape lighting, weatherproof outlets, and exterior fixtures of all kinds. Outdoor wiring requires GFCI protection and weatherproof-rated fixtures to meet code and hold up to Pennsylvania weather. We'll get your lights back on fast.
What sets our electricians apart is straightforward: we show up, we do the work, and we stand behind it. We serve residential and commercial customers across Bethlehem and Northampton County, from single-family homes and rental properties to offices, retail spaces, and commercial buildings.
On the residential side, we work with homeowners and landlords who need reliable electrical service and a crew that respects the property. On the commercial side, we handle office electrical work, commercial panel upgrades, tenant improvement wiring, commercial lighting installation, and the dedicated circuits that keep equipment running. We pick up the phone and get it handled. Call (484) 916-4289 to get started.
An electrical inspection gives you a clear picture of what is in your walls and whether it meets current code. We perform home electrical inspections, pre-sale inspections, and code inspections for buyers, sellers, landlords, and homeowners who simply want to know where things stand. In older Bethlehem properties, an inspection often turns up issues that have been quietly present for years.
A safety inspection visit is also a natural time to add smoke detectors and carbon monoxide detectors if yours are overdue for replacement. Whole-home surge protection is another proactive measure we recommend and install: one device at the panel protects every circuit in the house from voltage spikes that can damage electronics and appliances without warning.
Bethlehem's older housing stock, growing EV adoption, and the region's seasonal storms create consistent demand for a handful of specialized services. These are the jobs we handle regularly in this area.
A large share of Bethlehem's homes were built before modern wiring methods existed. Knob-and-tube wiring was standard construction through the mid-twentieth century, and aluminum branch wiring was widely used in the 1960s and 1970s. Both present real concerns today. Knob-and-tube lacks a ground conductor and was not designed for modern electrical loads. Aluminum branch wiring can loosen at connections over time and create heat and fire risk. Many insurers restrict or surcharge coverage on homes with either type. We assess what is in place, explain your options honestly, and perform aluminum wiring remediation or whole-home rewiring to bring the system up to current code. Work is performed by licensed electricians from start to finish.
Pennsylvania EV adoption continues to climb, and Bethlehem is no exception. A Level 2 home charger is the practical choice for daily charging, but it requires a dedicated 240-volt circuit and enough panel capacity to support it. Many homes in the area need a panel evaluation before a charger goes in, and some need an upgrade to make the math work. We handle the full electrical side: circuit installation, EV charger wiring, and any panel work required to carry the load safely.
Nor'easters and ice storms hit Northampton County hard, and power outages that last hours can stretch into days. A properly installed backup generator changes that equation. We handle standby generator hookups, portable generator hookups, and the transfer switch installation that makes the whole system safe and code-compliant. The transfer switch is the critical piece: it isolates your home's wiring from the utility line so power cannot back-feed onto the grid. We size and install the dedicated circuit, connect the transfer switch, and integrate everything cleanly with your existing panel.
We serve Bethlehem and the communities around it throughout Northampton County and the broader Lehigh Valley. Nearby towns we cover regularly include Easton, Allentown, Nazareth, Hellertown, Whitehall, and Fountain Hill. If you are just outside this list, call and ask. Chances are good we cover your area.
We are available every day from 5:30 AM to 9:30 PM, including weekends. For situations that cannot wait, we offer emergency availability outside those hours as well. Call (484) 916-4289 and we will get someone out to you as quickly as possible.
Call (484) 916-4289 and tell us what you are dealing with. We will ask a few quick questions, give you an honest sense of what the job likely involves, and get a licensed electrician scheduled for the same day when slots are available.
Flickering lights, outlets that are warm or discolored, breakers that trip repeatedly, a burning smell near a panel or switch, and rooms that lose power without explanation are all signs that something needs attention. These symptoms can point to overloaded circuits, failing devices, or wiring issues that get worse if left alone. Do not wait on any of them.
When we come out, we assess the situation and give you a clear picture of what the work involves and what it will cost before anything starts. If the job turns out to be more involved than expected once we are into it, we tell you before we proceed. There are no surprise charges added after the fact.
Yes. We work with homeowners, landlords, property managers, and business owners across Bethlehem and Northampton County. Whether the job is a single-family home, a rental unit, a retail space, or a commercial building, we bring the same level of care and attention to the work.
Absolutely. We work with property managers and landlords who need reliable electrical service across multiple units or locations. Call us to talk through your situation and we will figure out the best way to coordinate the work.
It depends on the scope of the work. A single outlet replacement or breaker swap can be done in under an hour. A panel upgrade or partial rewire typically takes most of a day. When you call, we will give you a realistic time estimate based on what you describe, and we confirm the details when we are on-site.

| Type of Work | What's Included | When You Need It | Worth Knowing |
|---|---|---|---|
| Code-Correction Wiring |
| homeowners who received a failed inspection, an insurance requirement, or a notice from a home sale | Code corrections are often straightforward once we know exactly what is flagged. We give you a clear scope before any work begins. |
| Electrical Panel & Service UpgradesMost Popular |
| older homes adding appliances, EV chargers, or generators, and any property with a fuse box still in service | A properly sized panel is the foundation of a safe electrical system. We size the new panel to your actual demand and handle the permit and inspection process. |
| Knob-and-Tube & Aluminum Rewiring |
| owners of Bethlehem homes built before 1980 with original or partially original wiring | Many insurers restrict or surcharge coverage on homes with knob-and-tube or aluminum branch wiring. Work is performed by licensed electricians and brought fully up to current code. |
| Dedicated Appliance Circuits |
| homeowners adding a large appliance, workshop equipment, or any load that needs its own circuit | Dryers, ranges, and large appliances require a dedicated 240-volt circuit. Running one from an already-loaded panel may require a capacity evaluation first. |
| Wiring & Circuit Installation |
| homes being renovated, additions, or any property that needs new circuits added | Northampton County's older housing stock means rewiring projects are common here. We handle targeted rewiring of one section or the whole house. |
| Outlet & Switch Installation |
| homeowners updating older receptacles, adding outlets, or bringing a circuit up to code | Every outlet job includes proper grounding and bonding. GFCI protection is required in kitchens, bathrooms, garages, and outdoor areas. |
| Backup Generator Installation |
| homeowners and businesses preparing for nor'easters and extended outages in Northampton County | The transfer switch is the critical safety component. It isolates your home's wiring from the utility line so power cannot back-feed onto the grid during an outage. |
| Whole-Home Surge Protection |
| any homeowner with sensitive electronics, smart home devices, or appliances worth protecting | One device installed at the panel protects every circuit in the house. It is a straightforward addition during any panel or service visit. |
| Electrical Repairs & Troubleshooting |
| any homeowner or business owner with an unexplained electrical problem | We trace the source of the problem, not just the symptom. A thorough diagnosis prevents the same issue from coming back. |
| Lighting Installation |
| homeowners updating interior lighting or adding outdoor security and landscape fixtures | Outdoor wiring requires weatherproof-rated fixtures and GFCI protection to meet Pennsylvania code and hold up to local weather. |
| Basement & Sump-Pump Circuits |
| homeowners finishing a basement or adding a sump pump, dehumidifier, or workshop in the lower level | Sump pumps should be on a dedicated circuit so a tripped breaker from another load does not leave the pump without power during a storm. |
| EV Charger Installation |
| Bethlehem homeowners adding a home EV charger for daily charging | A Level 2 charger requires a dedicated circuit and enough panel capacity to support it. Many homes in the area need a panel evaluation before installation. |
| Breaker & Fuse Repair |
| homes or businesses with breakers that trip repeatedly or a fuse box still in service | A breaker that trips repeatedly is a warning sign, not a nuisance. We find out whether the issue is the breaker, the circuit load, or the panel itself. |
| Electrical Safety Inspections |
| buyers, sellers, landlords, and homeowners who want a clear picture of their system's condition | In older Bethlehem properties, inspections regularly turn up issues that have been quietly present for years. Knowing what is there is always better than guessing. |
| Ceiling Fan Installation |
| homeowners adding or replacing ceiling fans in any room | Older ceiling boxes are often not rated for fan weight. We check the box and brace before installation so the fan is mounted safely. |
How do I know if my panel needs to be upgraded?
Common signs include breakers that trip repeatedly, lights that dim when a large appliance starts, a fuse box still in service, or a panel that simply does not have enough open slots for the circuits you need. If you are planning to add an EV charger, a generator hookup, or significant new load, a panel evaluation should come first. We look at the panel, assess your current demand, and give you a straight answer about whether an upgrade makes sense.
What causes breakers to trip over and over?
Repeated tripping usually points to one of three things: a circuit that is carrying more load than it was designed for, a failing breaker that no longer holds its rated current, or a wiring problem somewhere on the circuit. Occasionally it signals that the panel itself is undersized for the home's demand. We diagnose the actual cause rather than just resetting the breaker and hoping it holds.
Is the work permitted and inspected?
For jobs that require a permit under Pennsylvania and local Bethlehem codes, we handle the permit process as part of the job. Permitted work is inspected by the local authority, which gives you documentation that the installation meets current code. That matters for insurance, for home sales, and simply for knowing the work was done correctly.
Work Performed by Licensed Electricians
Every job we take on is handled by licensed electricians from start to finish. That means the work meets code, holds up to inspection, and gives you documentation you can rely on for insurance and home sales.
How do I know if the wiring in my older Bethlehem home is safe?
Homes built before 1980 may have knob-and-tube wiring, aluminum branch wiring, or both. Neither is automatically a crisis, but both require an honest assessment. Knob-and-tube lacks a ground conductor and was not designed for modern electrical loads. Aluminum branch wiring can loosen at connections over time and create heat at those points. An inspection gives you a clear picture of what is in the walls and what, if anything, needs to be addressed.
What does a Level 2 EV charger installation involve?
A Level 2 charger runs on a dedicated 240-volt circuit, similar to a dryer outlet. The installation involves running that circuit from your panel to the charger location, mounting the charging unit, and confirming the panel has enough capacity to carry the added load. Many homes in the Bethlehem area need a panel evaluation before the charger goes in, and some need a panel upgrade to make the load work safely. We handle the full electrical side of the job.
How does backup generator hookup work, and why does the transfer switch matter?
We connect the generator to your home's electrical system through a transfer switch, which is the component that makes the whole setup safe and legal. The transfer switch isolates your home's wiring from the utility line whenever the generator is running, which prevents power from back-feeding onto the grid and endangering utility workers. Without a proper transfer switch, a generator hookup is a code violation and a genuine safety hazard. We size the circuit, install the transfer switch, and integrate everything with your existing panel.
Experienced With Older and Newer Homes
We work regularly in Bethlehem's older housing stock, where knob-and-tube wiring, aluminum branch circuits, and undersized panels are common. We also wire new construction and additions. Whatever the property, we know what we are looking at.
Do I need to be home while the work is being done?
For most jobs, yes. We need access to the panel, the affected circuits, and often multiple rooms. For larger jobs like rewiring or panel replacement, someone should be available for the duration. When you call to schedule, we will let you know what access we need so you can plan accordingly.
When should I call an electrician instead of trying to fix it myself?
Anything beyond replacing a light bulb or a plug-in device is worth a call. Outlet and switch replacement, breaker issues, wiring work, and anything inside the panel are jobs for a licensed electrician. The risk with electrical DIY is not just a shock hazard in the moment. Improper wiring can create fire risk that shows up weeks or months later. If you are not certain, call and describe what you are seeing. We will tell you honestly whether it is something we need to handle.
Same-Day and Emergency Availability
Electrical problems do not wait for a convenient time, and neither do we. We are available for same-day service and after-hours emergencies for both residential and commercial customers across Northampton County.
Are warm or buzzing outlets something to worry about?
Yes. A warm outlet usually means there is resistance at a connection, which generates heat. A buzzing sound from an outlet or switch often points to a loose wire or a failing device. Both are worth addressing promptly. Left alone, a loose or overheating connection can damage wiring inside the wall or become a fire hazard. Call us and we will get a look at it.
What does GFCI protection do, and where is it required?
A GFCI outlet or breaker monitors the circuit for a ground fault, which is an unintended path for current, and cuts power in a fraction of a second if it detects one. That response time is fast enough to prevent a serious shock. Code requires GFCI protection in kitchens, bathrooms, garages, unfinished basements, outdoor areas, and anywhere near water. If your home does not have GFCI protection in those locations, we can add it as a standalone job or as part of any other electrical visit.
How long does a panel upgrade or whole-home rewire take?
A panel upgrade typically takes most of a working day. A whole-home rewire depends on the size of the house and the condition of the existing wiring, but plan on multiple days for a full rewire of an average-sized home. When you call, we will ask about the property and give you a realistic time estimate before we schedule. We confirm the details once we are on-site and have seen the full scope.
Every property is a little different, and the right solution depends on what is actually in your walls. Call us at (484) 916-4289 and we will give you a straight answer about what the job involves and what it will cost.
