Home Wiring Advice – Be Careful Where You Get It From


By Dave Rongey - Summary:

Beware of Bad Advice about Home Electrical Wiring – Silly advice and incorrect information can be a problem – This circuit wire size should always stay the same size with few exceptions, and yes, a 15 amp circuit breaker is the right size for 14 AWG copper.

Bad Home Wiring Advice About an Electrical Circuit

Electrical Question: I just put in a new circuit on a 15amp breaker that only has lights on it.

I was all ready to attach it to the new breaker, but the guy at Home Depot just told me that I can’t attach 14 AWG wire directly to the breaker. Instead, I have to either run 12-2 to the first light (and then I can run 14-2 to the rest of the lights), or I have to have a junction box just outside of the breaker box, where I change from 12-2 to 14-2.
This seems silly.

Is it really true that I’m not allowed to attach 14-2 directly to the 15amp breaker?

    Code your wire first and save yourself a lot of headaches by identifying the wires as you install them. It’s a lot harder to figure out which wires go where when they’re covered with drywall. The electricians we talked to use a “code” for marking wires, and so can you. Here’s one example. Wrap three-way switch “travelers” loosely and wrap the common wire tightly around them for easy identification later.
