New user here. I have a question regarding wiring a new bathroom in our basement.
We are in a new home, just completed 5 months ago. All work originally performed was done by licensed contractors, using a general contractor. A bath was roughed in in the basement, and we are getting ready to start finishing the basement.
After reading through the forum, I see that every where a bath is concerned, it almost always says that a dedicated 20a circuit is required for a bath. This confuses me, since the just completed house has only 15a circuits going to our baths, and they also share with other receptacles in adjacent hallways. All of the work was inspected properly by the township we are located in, I was there when some of the inspections were done so I know (at least I believe) that they were properly inspected. I was personally there when the rough electric was inspected, and it was clear that it was 14-2 wiring being used. The only 20a breakers in the panel (and the only yellow 12-2 wiring run through the house) is for the kitchen, kitchenette and dining room circuits. I have counted the # of 20a breakers, and also the # of 12-2 cables (yellow) that leave the panel, and they match.
I was planning on using 14-2 cable for the new bath, but am unsure of why everone says 12-2 must be used when the new home didn't use that.
