Basic House Wiring Safety Tips

  • Do Not Overload.

How many outlets can be on a 20a breaker?

ten outlets
The answer to the question how many outlets on a 20 amp circuit is ten outlets. Always comply with the 80% circuit and breaker load rule, allowing a maximum load of 1.5 amps per receptacle. Remember that your circuit, wire sizes, and outlets must be compatible to avoid overheating and electrical hazards.

How far apart should outlets be?

twelve feet
There’s a reason for that. The US National Electrical Code, Section 210.52, states that there should be an electrical outlet in every kitchen, bedroom, living room, family room, and any other room that has dedicated living space. They must be positioned at least every twelve feet measured along the floor line.

Can you have lights and outlets on the same circuit?

In your case it is okay to install a receptacle alongside the switch. However you need a neutral as well as a hot wire which you may not have. Test to see if you have a neutral with a test light or meter. The neutral will be white but some switches are wired up with a white wire that is not a neutral.

How high off the floor should outlets be?

about 16-inches
As for typical heights, that isn’t as well-regulated (and we’re glad for that). 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.
