The best way to prevent an unnecessary electrical disaster in your home, including frequent breaker trips, is to spread the amp load throughout the breakers in your electrical panel. You can combine electrical receptacles and overhead lights on one circuit due to the fact that lights generally draw significantly less power than large appliances. This will allow you to distribute the power consumption throughout the breakers in your panel effectively.
How many outlets does a house need?
You will want to ensure that certain rooms in the home have more than one receptacle, such as the kitchen. This is to ensure you still have power in the event one breaker ends up tripping for whatever reason. There are some appliances, such as the dishwasher, dryers, and washing machines, in the kitchen and the laundry room that will require a dedicated circuit for each appliance. This means that only that appliance can be on that circuit and nothing else—not even some light bulbs or a light fixture.
Space heaters are another example of heavy-duty appliances that take the maximum draw of the entire circuit. An air conditioner is another. Ideally, you should spread as many outlets around your home as possible and assign them to a single circuit. Just keep in mind the maximum load for a single circuit. A good rule of thumb is to assume that there will be a maximum power draw of 1.5 amps for each outlet, allowing 10 outlets for a single 20-amp circuit.
The primary rule is what’s known as the 6’/12′ rule. NEC 210-52 states the following:
Receptacles are needed in every room of a home such that no point on a wall is over 6′ from an outlet. This means that you need an outlet within 6′ of a doorway or fireplace. A long wall, however, may have up to 12′ between outlets. Any outlet above 5′ 6″ cannot be counted towards this equation. Floor outlets less than 18″ from the wall can.
There are also other guidelines that need to be followed. For example:
- Every hallway should have at least one receptacle if it is 10′ or longer in length
- Kitchen countertop outlets require at least two 20-amp circuits and must have GFCI protection. Allow no more than 4 feet between countertop outlets.
Generally, you want to mount receptacle boxes with the bottom of the box about 16-inches off the floor. Coincidentally, this roughly equates to the same height as your garden variety 22-ounce framing hammer. We still recommend using a ruler, however.
For kitchen countertops, how high you mount the receptacles depends on your layout. There are no height guidelines except to keep them under a maximum of 20-inches. This seems obvious since the top cabinets start at 18″). Placement somewhat depends upon how you intend to do the backsplash. If you mount the bottom of the box about 2-3 inches above the top of your tile, solid surface, or stone backsplash, you’ll have a nicely positioned outlet that is easy to access. For refrigerators, you have some flexibility. Typically, we mount these outlets about 48-inches off the floor.
