An electrical inspection checks the service panel, wiring, outlets, and safety devices. Key concerns are outdated panels, unsafe wiring types, missing grounding, and overloaded circuits.
Power enters through the service panel, where breakers protect circuits that feed the home. Most modern homes have 100 to 200 amp service.
| Key point | What it means |
|---|---|
| Knob-and-tube wiring | Found in some homes built before the 1940s; no ground and aging insulation. |
| Aluminum branch wiring | Used in some 1960s and 1970s homes; connections need special attention. |
| Ungrounded two-prong outlets | Common in older homes and less safe. |
| Certain older panel brands | Inspectors may flag panels with a history of breaker problems. |
Scorched or buzzing breakers, double-tapped breakers, missing cover screws, open junction boxes, and DIY wiring. GFCI outlets should protect kitchens, baths, garages, and outdoor areas, and AFCI breakers are common in newer work.
Don’t try to evaluate electrical issues yourself. If an inspector flags concerns, a licensed electrician can give a repair estimate. Insurance companies may also have questions about older panels, so ask early.
