Welcome to Home Improvement Stack Exchange

Home Improvement is a question and answer site for contractors and serious DIYers. The core of this site is around parts of your home that are typically included when you buy or sell it, the structure, utilities, and major appliances.

It's built and run by you as part of the Stack Exchange network of Q&A sites. With your help, we're working together to build a library of detailed answers to every question about home improvement.

We're a little bit different from other sites. Here's how:


Ask questions, get answers, no distractions

This site is all about getting answers. It's not a discussion forum. There's no chit-chat.

Just questions...

...and answers.

up vote

Good answers are voted up and rise to the top.

The best answers show up first so that they are always easy to find.

accept

The person who asked can mark one answer as "accepted".

Accepting doesn't mean it's the best answer, it just means that it worked for the person who asked.

Three 15 A receptacles on a 20 A breaker

up vote 14 down vote

I need to wire three (3) 15 A receptacles. I also have some spare yellow 20 A Romex laying around.

Is there any issue with wiring those up? I got a dedicated 20 A breaker to daisy chain the three.

No problem doing what you want to do. Just make sure your cable is #12 AWG. Don't use the backstabs on the outlets, pigtail the first and second outlets on the through cable.

Yes, that’s fine. The NEC specifically allows multiple 15A receptacles on a 20A branch circuit. You must use 12Ga or larger (if in copper) for all wiring - any 14 and you must use a 15A breaker.

This is an exception to the general rules. You can’t put a single 15A receptacle on a 20A circuit and you can’t do things like putting multiple 20A receptacles on a 30A circuit.


Get answers to practical, detailed questions

Focus on questions about an actual problem you have faced. Include details about what you have tried and exactly what you are trying to do.

Ask about...

  • Questions you would typically ask a home contractor.
  • Which tools, materials, and best practices for home improvement task.
  • Identifying the source or cause of a problem within your home.
  • National building codes (of any country).
  • Installation, maintenance, and repair of major appliances.
  • Carpentry and woodworking.

Not all questions work well in our format. Avoid questions that are primarily opinion-based, or that are likely to generate discussion rather than answers.

Questions that need improvement may be closed until someone fixes them.

Don't ask about...

  • Anything not directly related to home improvement
  • Hobby projects, decorating advice or landscaping.
  • The cost of a job or the price of tools as these will vary between locations and over time.
  • Questions that are primarily opinion-based
  • Questions with too many possible answers or that would require an extremely long answer

Tags make it easy to find interesting questions

All questions are tagged with their subject areas. Each can have up to 5 tags, since a question might be related to several subjects.

Click any tag to see a list of questions with that tag, or go to the tag list to browse for topics that interest you.

You don't have to pigtail, but it'll be easier to push the recep back into the box if you do. Another "ease the pain" trick is use metal boxes + "self-grounding" receps. Then you land the grounds on the metal box (which you always must do) first, and then grounds are out of your way. Then the recep picks up ground off the mounting screw threads. 1 less wire to wrestle! - Harper - Reinstate Monica Feb 28 at 2:48
