    Sample Home Electrical Inspection Checklist


    ; Check for outlets that have loose-fitting plugs, which can overheat and lead to fire. __________________________________ ; Replace any missing or broken wall plates. _________________________________________________________________ ; Make sure there are safety covers on all unused outlets that are accessible to children. ______________________________ Line Cords

    ; Make sure cords are in good condition-not frayed or cracked. __________________________________________________ ; Make sure they are placed out of traffic areas. ______________________________________________________________ ; Make sure that cords are not nailed or stapled to the wall, baseboard or to another object. ____________________________ ; Make sure that cords are not under carpets or rugs or any furniture rests on them. __________________________________ Extension Cords

    ; Check to see that extension cords are not overloaded & only be used on a temporary basis, not as permanent wiring. ______

     __________________________________________________________________________________________________ ; Make sure extension cords have safety closures to help protect children from shock hazards and mouth burns. ___________

     __________________________________________________________________________________________________ Plugs

    ; Make sure your plugs fit securely into your outlets. ___________________________________________________________ ; Make sure no plugs have had the ground pin (the third prong) removed in order to make a three-prong fit a two-conductor

    outlet; this could lead to an electrical shock. _______________________________________________________________ ; Never force a plug into an outlet if it doesn't fit. ______________________________________________________________ ; Avoid overloading outlets with too many appliances. __________________________________________________________ Ground Fault Circuit Interrupters (GFCIs)

    GFCIs can help prevent electrocution. When a GFCI senses current leakage in an electrical circuit, it assumes a ground fault has

    occurred. It then interrupts power fast enough to help prevent serious injury from electrical shock. GFCIs can be installed at the

    outlet, or as a replacement for the circuit breaker for an entire circuit at the fuse box.

    ; Kitchen ; Bathrooms ; Garage ; Laundry room ; Outdoors

     __________________________________________________________________________________________________ ; Test GFCIs according to the manufacturer's instructions monthly and after major electrical storms to make sure they are

    working properly. ____________________________________________________________________________________ Light Bulbs

    ; Check the wattage of all bulbs in light fixtures to make sure they are the correct wattage for the size of the fixture. __________

     __________________________________________________________________________________________________ ; Replace bulbs that have higher wattage than recommended; if you don't know the correct wattage, check with the

    manufacturer of the fixture. ____________________________________________________________________________ ; Make sure bulbs are screwed in securely; loose bulbs may overheat. ____________________________________________ Circuit Breakers/Fuses

    ; Make sure circuit breakers and fuses are the correct size current rating for their circuit. If you do not know the correct size,

    have an electrician identify and label the size to be used. Always replace a fuse with the correctly specified size fuse. ______

    ; Make sure everyone in your home knows where the main breaker is located and how to shut of power to the entire house.

    Sample Home Electrical Inspection Checklist (page 2)

    Plug In Appliances

    ; Make sure there are no plugged-in appliances where they might fall in contact with water. If a plugged-in appliance falls into

    water, NEVER reach in to pull it outeven if it's turned off. First turn off the power source at the panel board and then unplug

    the appliance. If you have an appliance that has gotten wet, don't use it until it has been checked by a qualified repair person.


    ; If an appliance repeatedly blows a fuse, trips a circuit breaker or if it has given you a shock, unplug it and have it repaired or

    replaced. __________________________________________________________________________________________ Entertainment/Computer Equipment

    ; Check to see that the equipment is in good condition and working properly. Look for cracks or damage in wiring, plugs and

    connectors. ________________________________________________________________________________________ ; Use a surge protector bearing the seal of a nationally recognized certification agency. _______________________________ Outdoor Safety

    ; Electric-powered mowers and other electric tools should not be used in the rain, on wet grass or in wet conditions. _________

     __________________________________________________________________________________________________ ; Inspect power tools & electric lawn mowers before each use for frayed power cords, broken plugs & cracked or broken

    housings. If any part is damaged, stop using it immediately. Repair it or replace it. _________________________________

     __________________________________________________________________________________________________ ; Always use an extension cord marked for outdoor use and rated for the power needs of your tools. _____________________ ; Remember to unplug all portable power tools when not in use. _________________________________________________ ; When using ladders, watch out for overhead wires and power lines. Stay at least 10 feet from all overhead lines. __________

     __________________________________________________________________________________________________ Lightning

    ; During an electrical storm, do not use appliances (i.e., hairdryers, toasters and radios) or telephones (except in an emergency);

    do not take a bath or shower; __________________________________________________________________________ ; Keep batteries on hand for flashlights and radios in case of a power outage. _______________________________________ ; Use surge protectors on electronic devices, appliances, phones, fax machines and modems. _________________________ Space Heaters

    ; Space heaters are meant to supply supplemental heat. Keep space heaters at least 3 ft. away from any combustible materials

    such as bedding, clothing, draperies, furniture and rugs. _____________________________________________________ ; Don't use space heaters in rooms where children are unsupervised and remember to turn off and unplug when not in use.

     __________________________________________________________________________________________________ ; Do not use space heaters with extension cords; plug directly into an outlet on a relatively unburdened circuit. _____________

    Halogen Floor Lamps

    ; Halogen floor lamps operate at much higher temperatures than a standard incandescent light bulb. Never place a halogen floor

    lamp where it could come in contact with draperies, clothing or other combustible materials. __________________________

     __________________________________________________________________________________________________ ; Be sure to turn the lamp off whenever you leave the room for an extended period of time. _____________________________ ; Never use torchiere lamps in children's bedrooms or playrooms. Consider using cooler fluorescent floor lamps. ___________

    Sample Home Energy Audit

    (from Energy Merit Badge)

    Remember that even a gas furnace uses an electric fan so saving heat saves electricity.


    ; Insulation - Is there enough insulation between ceiling joists?

    ; Vents - Sufficient and unobstructed?

Living Areas

    ; Air Leakage - Tape a foot of toilet paper to a pencil with paper hanging free. Hold near windows and doorframes, window air-

    conditioning units, and electrical covers. If paper moves, you may need weather-stripping, caulking, or storm windows. ; Wall Insulation - Are the wall too cool to the touch on a cold day or too warm on a hot day? ; Thermostat - Set at 68 degrees in winter (turn down 5 degrees more when sleeping), 78 in summer. ; Drapes - During winter, open drapes and shades to let sunlight in. Close at night. During the summer, close drapes. ; Unused Rooms - Close heating and cooling vents, doors in areas seldom used.

    ; Use fans instead of air conditioning when possible. Fans can also help circulate air when the air conditioning is on.


    ; Close the damper when fireplace is not in use.

    ; Glass doors keep heat from escaping up the chimney.


    ; Refrigerator/Oven Seal - To test, close a dollar bill in the door. If the bill moves with little resistance, the seal is bad. ; Appliances - Use washers and dryers in the morning and late evening hours when energy requirements are lower. ; Lights - Turn off lights when not used. Install lower wattage and fluorescent light bulbs whenever possible. ; Faucets do not drip.

Basement/Crawl Space

    ; Heating/Cooling System - Clean or replace filters monthly. Have unit serviced once a year. ; Water Heater - Set temperatures no higher than 160 degrees. Drain sediments 3-4 times a year. ; Ducts/Pipes - Insulate hot water pipes as well as heating and cooling ducts.

    ; Floors - If you have a crawl space under your house, install batt-type fiberglass insulation under floors. ; Venting - Washer & dryer units should be vented directly to the outside.


    ; Weather Stripping & Caulking - Caulk the cracks around windows, weather-strip around doors. ; Windows - Storm windows and double-paned glass can reduce energy usage up to 15%.

    ; Doors - Keep doors tightly closed on hot or cold days.

    ; Storm Doors - Help insulate doors
