I'm in the process of finishing my basement. So far, framing's done, HVAC ductwork's done, and I'm now working on the electricals.
So I've got a 60amp subpanel bringing in power, and off of this, I have a few circuits. This question is about the bathroom circuit.
I need to wire the bathroom with a GFCI outlet, (and downstream from it) a couple of lights and an exhaust fan. In addition, the GFCI will also supply 6 other receptacles, one of which will probably serve a refrigerator. I've already bought a 20amp AFCI breaker (and also have a couple of spare 15amp AFCIs, so can use either).
Here are my questions:
- Can I use a 15amp AFCI to supply this bathroom and the additional outlets, with 14 gauge wire?
- If I must use the 20amp, can I use 12/2 only up until the GFCI and then 14/2 from that point onwards? Of course, the light and fan will use a 14/3 for convenience.
- Is it acceptable to chain a refrigerator off of a bath circuit? No dishwashers, garbage disposals, etc.
- In the future, will this (either 15amp or 20amp) breaker support a portable microwave oven? Say, 1000W?
