Bathroom, 15 or 20 amp?
 
I read here and everywhere else that batroom should be 20 amp. But I was reading Black&Decker home wiring book and there is a sample of a plan and it states 15 amp.
Can you use 15 amp for 1/2 bath atleast?

A bathroom receptacle must be 20a. Black & Decker is just wrong, and not just about bathroom wiring.

It might be an old book. Years ago a dedicated 15A circuit was code legal. Not a good idea, but legal.

The book I have, shows 14/2 (15a) for Lighting, and 12/2 for (20a) circuit on page 159. This is under NEC 2005, but the drawing shown is for more of example purposes, and most likely to simulate what a homeowner had drawn out for what was in the home.

Bathroom lighting on a 15A (14/2) is OK, as long as there is a separate 20A (12/2) circuit for the receptacles.

I had to look at the drawing a 2nd time, and it is wired from a Sub-Panel, in order of wiring: GFCI, with a leg to the switch, and to a Closet light. From the switch, it goes to the light above the sink, and Vent fan. The Wall heater comes off of the same sub-panel, to another heater in the loop.

Their description is:
Circuit #1: A 15-amp, 120-volt circuit serving the bathroom and closet area. Includes: 14/2 NM cable, double-gang box, timer switch, single pole switch, 4x4 box with single gang adapter plate, GFCI recepticle, 2 plastic light fixture boxes, vanity light fixture, closet light fixture, 15-amp single pole breaker.

The space is a 400-sq ft. space.

If they are including the GFCI for the bathroom, then , yes, that is definitely wrong. Probably written by a former HD employee.:laughing:

Maybe written by someone in China. lol:laughing:

They didn't have a code book.
