Home Inspections
It is not unusual for a home inspector to find a #14 wire (15 amp circuit) connected to a 20 amp breaker. When a 15 amp circuit is overloaded and the circuit breaker trips often, someone may replace the 15 amp breaker with a 20 amp breaker. This situation could be a fire hazard or cause the whole circuit to fail.
If a 15 amp circuit is overloaded and the breaker trips often, the load(s) should be connected to another circuit, or a new circuit should be installed.
Electrical Systems Inspection
An electrical systems inspection and testing typically includes the following:
- GFCI protection for kitchen countertops, bathrooms, garages, outdoors, within six feet of a sink, unfinished basements, and boathouses.
- Service-
entrance, electric meter, and main disconnect. - Outlets and switches are in working order.
- Any wire connections that are not inside of an electrical box.
- Smoke alarms are present.
Electrical Pre-Inspection
An electrical pre-
Outlets can be tested with a receptacle outlet tester that has a GFCI test button. This tester shows if the outlet has power and if it is wired correctly. If plugs fit loosely in an outlet, it should be replaced.
- Homeowners usually know if the switches are working, any switches that are normally not used should be tested.
- Test all GFCI outlets by pushing the button on the tester to see if power shuts off (an audible click can be heard). Press the reset button to restore power. If the test or reset button does not work, and there is power at the GFCI, the GFCI has failed and needs to be replaced.
- While testing GFCIs, see if you lose power to other GFCIs. If another GFCI loses power, it should be replaced with a standard outlet. See GFCI Connected to the Load of Another GFCI.
- In kitchens, bathrooms, outdoors, etc, test all standard outlets with a receptacle outlet tester to determine if they are GFCI protected. Insert the tester into the outlet and verify it has power, then press the GFCI test button on the tester. If power shuts off, the standard outlet is GFCI protected. If the power does not shut off, it should be replaced with a GFCI outlet.
- Test all other standard outlets with the tester to see if they are wired correctly.
Home inspections are a part of the home sale process. They are usually done sometime after a purchase agreement is signed. A purchase agreement should contain a clause that the sale is contingent on the results of an inspection. A new mortgage or a home warranty typically requires an inspection.
It is a good idea for the buyer to have a home inspected before it is listed for sale, especially if the seller wants a fast closing. Any problems found can be fixed before the home gets listed and there won’t be any costly surprises after the agreement is signed.
What is a Home Inspection?
A home inspection is an inspection of the structure and systems of a house. They typically include the foundation, basement, heating system, plumbing, central air conditioning, electrical, roof, and attic. An inspection should be done by someone who is certified by the American Society of Home Inspectors (ASHI).
Electrical Panel Inspection
During an electrical panel inspection the inspector typically looks for the following:
- Clearance in front and top of the panel (3 feet deep and 30 inches wide) (6 feet headroom on top of panel).
- Proper wiring, grounding, and bonding.
- Discolored, oxidized, corroded, or damaged wires.
- Correct circuit breaker or fuse amperage ratings. Breaker size shall be 15 amps for #14 (AWG) wire, 20 amps for #12 wire, and 30 amps for #10 wire, and 40 amps for #8 wire.
- Only one wire is allowed to be connected to each circuit breaker.
- Check for copper and aluminum wires and whether the breakers are listed for copper or aluminum.
