Hi,
I am currently refitting a bathroom which has an existing electric shower connected to a dedicated RCD. The shower is going but I am looking to fit undertile heating, an electrical element for a towel heater and also a new extractor fan/light. I was hoping to use the RCD for the undertile heating but can I then spur off to the other devices or do they need to be on seperate RCD's? I am hoping to do the work myself and get it tested by a local sparky, is this a good idea?
