Panel upgrade pricing depends on your current service size, the condition of your meter base, and permit fees from your local jurisdiction — costs climb with complexity. Nexen Electric gives you a flat-rate quote specific to your home before any work starts. No hourly surprises, no number that changes when we show up.

Yes. Any new circuit, panel upgrade, or significant wiring work requires a permit in Maryland. Baltimore City, Baltimore County, Howard County, and Anne Arundel County all require permits and inspections. As a licensed master electrician, Nexen Electric pulls all permits and handles inspections for you — it's included in the job.

The clearest signs: breakers that trip frequently, a 100-amp panel (most homes today need 200 amps), a fuse box instead of breakers, flickering lights when appliances kick on, or you're adding a major load like an EV charger, hot tub, or home addition. If your home was built before 1990 and hasn't been updated, a panel upgrade is worth discussing.

A 100-amp panel was standard for homes built before the 1980s. Today, between central air, EV chargers, home offices, and modern appliances, most Baltimore-area homes need 200-amp service. A 200-amp panel doubles your capacity — and home inspectors routinely flag 100-amp panels during sales, which can slow down or derail financing on older Maryland homes.

Most Level 2 EV charger installations take 2–4 hours. If a new 240V dedicated circuit needs to be run from your panel to the garage, plan for a half-day job. Nexen Electric installs NEMA 14-50 outlets and hardwired Level 2 chargers throughout Baltimore County, Howard County, and Anne Arundel County.

The most common causes are an overloaded circuit (too many devices pulling power from one breaker), a short circuit in a device or outlet, or an aging breaker that's starting to fail and trips at lower loads than it should. A breaker that trips once is doing its job. A breaker that trips repeatedly is telling you something is wrong — either the circuit is undersized for the load, or the breaker needs replacing. Nexen Electric diagnoses the root cause, not just resets it.

Three types of panels show up constantly in Baltimore-area homes — and all three are serious concerns. Fuse boxes (pre-1960s) can be overfused: someone installs the wrong amperage fuse, the circuit protection stops working, and undersized wiring carries more current than it can handle. Federal Pacific Electric (FPE) Stab-Lok panels, installed widely from the 1950s through the 1980s, have documented breaker failure rates — the breakers don't trip during overloads the way they're supposed to, which is exactly how electrical fires start. Zinsco panels (also sold as GTE-Sylvania) have the same problem: breakers can physically fuse to the bus bar and become unable to trip at all. All three are flagged by insurance companies — expect higher premiums, coverage refusals, or a required replacement before a policy is issued. If your home was built between 1950 and 1985 and the panel has never been replaced, there's a real chance you have one of these. A panel evaluation takes about an hour and tells you exactly where you stand.

In Maryland, unlicensed electrical work is illegal — full stop. Beyond the legal exposure, it can void your homeowner's insurance: if a fire or electrical incident is traced back to unpermitted or unlicensed work, insurers have grounds to deny the claim. Master electrician is the highest license tier Maryland issues. It requires passing state board exams, documented field experience, and ongoing compliance with the National Electrical Code. A master electrician carries liability insurance, pulls the required permits, and gets the work inspected — so there's a paper trail proving everything was done to code. That matters when you sell. Home inspectors flag electrical code violations and unpermitted work as a matter of course, and unpermitted electrical is one of the most common deal-killers in Baltimore-area home sales. A handyman can't pull a permit in Maryland. That means no inspection, no record, and full liability on you if something goes wrong.
