bathroom remodel

wibago

Hello all.

I am remodeling a bathroom and could use some advice. The vanity light is on a 15A circuit shared by another room's lights. The receptacle is on a 20A circuit shared by the other bathrooms and fed by a 20A GFCI breaker. I wanted to install a fan and a light in the shower. I am wondering if they need to be on a GFCI circuit or if can they simply be added to the 15A light circuit. And if they need to be GFCI protected, would it be better to run a new 20A circuit to this bath and remove it from the other circuits so that I can have the lights and receptacle on one circuit? The light I bought for the shower is rated for that use and the fan is just a vent, with no heater or integrated light fixture. By the way, I am an electronics engineer with 20 years of experience: 15 years in embedded microprocessor systems for missile guidance systems and now I work for Square D designing metering products. I have done some home wiring in the past, but that was before I had designed products that had to go through safety testing (UL 508, IEC 61010-1, etc.) So I am knowledgeable, but still somewhat new to the electrical code, and I just want to do things right so that it will be safe and legal when it comes time to sell the house.

I'm not sure you are asking in the right place! This question isn't really specific to Cork city.

Only a registered electrical contractor is permitted by law to do electrical work in bathrooms (not even in your own home)

the circuit would require 10amp rcbo protection

if you want to do things right then get a rec in to do the work and provide a certificate of compliance for the work done

15 amp circuit is fine for a fan they draw barely an amp. If spurring off the light, I'd put a switch with an FCU instead of a switch.
