Why You Need an Electrical Safety Inspection
Most people call for an electrical inspection when buying a home, after storm damage, or when selling. But age alone is reason enough. Homes built before 1985 often have outdated wiring—aluminum branch circuits, ungrounded outlets, no GFCI or AFCI protection. Insurance companies sometimes require an inspection before covering older properties.
An inspection isn't about passing or failing. It's a snapshot of risk. A licensed electrician identifies hazards—overloaded circuits, knob-and-tube remnants, loose connections that arc and heat up. You get a written report listing urgent fixes and recommended upgrades. That lets you prioritize: replace a charred breaker now, budget for a panel upgrade next year.
If you're buying, the inspection gives you leverage to negotiate repairs or price. If you're selling, a pre-listing inspection lets you fix problems before they tank a deal. Either way, you know what you're working with.
The Main Electrical Panel
Inspectors start at the panel. They check the service rating—100A panels are common in older homes, but modern loads (central AC, electric range, EV charger) often need 200A. They look for Federal Pacific or Zinsco panels, both known to fail catastrophically; many jurisdictions flag them as immediate safety hazards.
Inside the panel, inspectors verify proper breaker sizing for each circuit. A 15A breaker on 14-gauge wire is correct; a 20A breaker on the same wire is a fire risk. They check for double-tapped breakers—two wires under one terminal—unless the breaker is rated for it. They look for rust, scorching, or melted plastic around terminals, signs of overheating or water intrusion.
They also confirm the main breaker works and that the panel has proper clearance—nothing stored within three feet. Grounding and bonding get inspected: the grounding electrode conductor to the ground rod or water pipe, the neutral-ground bond (which should exist only at the main panel, not at subpanels). If any of this is missing or wrong, the whole system's safety is compromised.
Branch Wiring and Circuit Load
Inspectors don't open every wall, but they check accessible wiring in attics, crawlspaces, and basements. They look for amateur splices—wires twisted together and taped instead of junction-boxed with wire nuts. They check for exposed Romex in garages or unfinished areas where code requires conduit. They verify that wiring is properly stapled and supported, not draped across joists or pinched by framing.
Aluminum branch wiring (common 1965-1973) gets flagged. Aluminum expands and contracts more than copper; connections loosen over time, arc, and start fires. If your home has it, inspectors recommend either CO/ALR-rated devices or a professional retrofit with copper pigtails at every termination.
Load calculation matters. Inspectors note how many circuits serve the kitchen, laundry, bathrooms. Modern code requires at least two 20A small-appliance circuits in the kitchen, a dedicated 20A laundry circuit, and GFCI-protected bathroom circuits. Older homes often have one 15A circuit feeding the entire kitchen—a recipe for tripped breakers and voltage drop when the microwave and toaster run together.
Outlets, Switches, and GFCI/AFCI Protection
Every accessible outlet gets tested. Inspectors use a plug-in tester to verify correct polarity (hot and neutral not reversed) and proper grounding. Reversed polarity is common in DIY work; it energizes parts of appliances that should be neutral, creating shock risk. Missing grounds in older two-prong outlets aren't code violations in existing work, but inspectors note them—especially in kitchens, baths, and outdoor locations where GFCI protection is now required.
GFCI outlets protect against ground faults—current leaking through you to ground. Code requires them within six feet of sinks, in bathrooms, garages, crawlspaces, unfinished basements, and all outdoor receptacles. Inspectors test the GFCI button on each protected outlet; if it doesn't trip, it's failed and needs replacement.
AFCI breakers protect against arc faults—sparking in damaged wiring that starts fires. Modern code requires them on most 15A and 20A circuits in living areas. Older homes don't have them. Inspectors note the absence as a recommended upgrade, not a violation, but insurance companies increasingly want AFCI protection before covering homes built before 2000.
Tamper-resistant receptacles (TRs) are required in all new construction and remodels where children might be present. Inspectors check for them in homes with recent work. Switches get tested for proper operation and secure mounting; loose switches indicate backstabbed connections that can overheat.
Dedicated Circuits and High-Draw Appliances
Major appliances need dedicated circuits—one device per circuit, nothing else. Inspectors verify that the electric range, dryer, dishwasher, garbage disposal, and HVAC equipment each have their own breaker. Sharing a circuit between a fridge and microwave might work until both compressors kick on at once, tripping the breaker and spoiling food.
Dryers require 30A, 240V circuits (typically a NEMA 10-30 or 14-30 outlet). Ranges need 40A or 50A. Central AC units and heat pumps need appropriately sized disconnects within sight of the unit. Inspectors check that the wire gauge matches the breaker—10-gauge copper for 30A, 8-gauge for 40A, 6-gauge for 50A. Undersized wire on a high-amp circuit is a fire waiting to happen.
If you've added an EV charger (Level 2 typically needs a 40A or 50A circuit), inspectors verify proper installation: NEMA 14-50 or hardwired EVSE, correct wire size, no voltage drop on long runs from the panel. They also check that your service can handle the added load without exceeding the main breaker rating.
Grounding, Bonding, and Surge Protection
Grounding provides a low-resistance path for fault current, tripping breakers instantly when a hot wire touches a metal enclosure. Inspectors verify that ground rods or a Ufer ground (rebar in the foundation) are present and properly connected. They check that metal water pipes, gas pipes, and structural steel are bonded to the grounding system—if a lightning strike or fault energizes a pipe, bonding ensures it trips the breaker instead of shocking someone.
Inspectors look for improper neutral-ground bonds in subpanels or at the meter. Only the main service panel should bond neutral to ground; doing it elsewhere creates parallel return paths, which can energize equipment grounds and cause shocks. This mistake is common in DIY subpanel installs.
Whole-home surge protection is increasingly recommended. Inspectors note whether a surge protector is installed at the panel (it should be, especially in Florida where lightning is frequent). Individual point-of-use suppressors protect sensitive electronics, but panel-level devices stop the big surges before they enter the system.
What Happens After the Inspection
You'll receive a written report—usually within 24-48 hours—listing every issue found, categorized by urgency. Immediate hazards include exposed live wiring, panels with scorch marks, any situation where someone could be shocked or a fire could start. Safety concerns cover missing GFCI protection, aluminum wiring, double-tapped breakers—things that should be fixed soon. Recommended upgrades include AFCI breakers, increasing service capacity, or adding circuits to reduce load.
For serious issues—Federal Pacific panels, widespread amateur wiring, service upgrades—get quotes from licensed electricians. Up-front pricing quoted before work starts means no surprises. For minor fixes (a failed GFCI, a loose outlet), most electricians can handle them during a single service call.
If you're in a real estate transaction, the report becomes a negotiation tool. Buyers can request repairs or credits; sellers can pre-emptively fix the big stuff and provide documentation. Either way, the inspection turns hidden risk into concrete action items. For more on our inspection and repair services, or to discuss findings from another inspector, reach out anytime.
