I'm making plans to replace electrical wiring (new wires) and breaker in my apartment. I live in New York city (for code purposes). My breakers are rated as 20 A, NOT GFCI/AFCI. I have some outlets in the living area that are GFCI. I read that in wet areas (kitchen/bath) it is required to have GFCI/AFCI outlets. I also read that stacking GFCI/AFCI protection is not safer, and some would leave them stacked with breaker, some would replace them with regular (non GFCI/AFCI) outlets.
PS: doing it with a certified electrician, of course! But I want to be informed, so here are my questions:
- Upgrading the current breaker with AFCI/GFCI breaker is the way to go, correct? I don't see a reason to not upgrade it. Is there a situation where it is not recommended?
- Is there any recent technology I should consider during this upgrade? I read a little about smart power monitor that is installed in the breaker.
- Considering the breakers will be converted to dual (GFCI + AFCI) protection, do I still need GFCI/AFCI outlets in wet areas? I would say no because everything is already covered by the breaker, but maybe the code still requires it for some reason.
- Considering the breakers will be converted to dual (GFCI + AFCI) protection, would it be OK to leave one or two GFCI/AFCI outlets in place, or it is recommended to replace them with regular outlets since breaker will already be GFCI/AFCI?
- My conduits are narrow (old). I rewired two places already. A solid wire is very hard to pass. A stranded is much easier. Would it be OK to use stranded in the whole apartment (living, kitchen, bath, etc.)?
- I will try to organize the breakers. Currently there is one breaker switching off lights and outlets in different (nearby) areas, I'd like to separate to have better control. Also, one dedicated breaker for the air conditioner. In case a conduit doesn't exit, is NM-B (Romex) cable an acceptable solution here? It seems to me it would require less work to install than a conduit.
- If I want to create new outlets in the bathroom (small bathroom), what would be the recommended procedure: break the wall and use NM-B cable? break the wall and install conduit? not break the wall and just use a wire cover with a waterproof cable like NM-B? This would be for a new outlet near the sink (shaving, etc.) and near the toilet for future electric bidet installation.
- Looking up online, I only find THHN stranded. I could not find THWN stranded wires. Why? It seems manufacturers might be using THHN even though they are also waterproof.
Thanks for helping!
