While replacing an outlet in the bedroom, I noticed that the breaker was 20 amp. The wires in the box looked small to me, so I traced the wire to the basement, and the wire is clearly marked 14 awg. It is a pretty extensive run of wire, and it would be very time consuming to replace the wire with 12 awg. The circuit only serves some lights and a tv, so I think that the best solution would be to replace the 20 amp breaker with a 15 amp breaker. Do you agree? Input greatly appreciated.

You MUST change the breaker to 15 amp if you are not going to change all the wire on the circuit to 12.

In addition to changing out the breaker, an inspection of the insulation on that circuit would be in order.

If it has been overloaded in the past, the insulation could be brittle and deteriorated.

Would an AFCI be in order?

Nooooooo... Not the "A" word again!!

That is a good question though.Would 210.12(B) apply for a replacement breaker in an existing dwelling?

ga.sparky56,

If it's a code requirement,why would you have to jusyify it to a GC or a homeowner?Just include it your bid.Don't you bid everyyhing else to meet code without having to justify what you need?

Donnie, in my area we have to justify everything the owner/GC/(s)he-who-writes-the-check doesn't think they need, and saying "it's code" usually gets the question "why?".

I've often got the "let's-sit-down-and-talk" thing many times from not only GC's but some folks at the supply house too, usually after the "that's what all the other electricians use/do" speech... the consensus being in a nutshell that if I don't "loosen up" and "be reasonable" then my business won't survive.

...as if I'm blowing things out of proportion by trying to adibe by code...



Code is right up there with Speed Limits, child support, and taxes...

Most around here in my parts think they're a good thing for everyone but themselves.
