Electrical Work

Use LED lighting throughout to cut down on power usage.
Use Energy Star appliances wherever possible.
Receptacles can be located at any height comfortable for the design, though typical height is at least 12 in. to 15 in. off the finished floor.
If you plan on installing outlet boxes above countertops, they should be 9 in. to 12 in. above the countertop.
When locating light fixtures overhead, make sure they are not in a hallway where the fixture might bang heads, but that they properly illuminate the walkway.
All outdoor boxes or boxes in wet areas should be waterproof and have a ground fault circuit interrupter (GFCI) breaker or receptacle.
Check with your local authority to make sure you are using the correct style of outlet box. Some authorities specify metal only, whereas others allow plastic boxes.
Use the appropriately shaped box. Outlets and switches use a 23/4- in. × 4 1/2 in. square box, whereas lighting outlets tend to use 6-in. round boxes in the ceiling. Note that many recessed lighting fixtures come with their own box. You should decide what you need before start the rough wiring installation to avoid multiple trips to the hardware store.
Make sure to specify the shortest distance between the outlet box and the main panel and to size the wire suitably for the circuit.
If you are planning to run two appliances at the same time- for example, you might run the coffee machine and the toaster at the same time while you have your computer and monitor plugged in- it’s best to put them on different circuits rather than plug them all into one outlet.
