I want to add a switched FCU to an existing installation of a bathroom extractor fan - I've searched through other postings here for the relevant diagrams.
I'm planning to replace the existing pull-cord light switch with a DP switch as advised here.
Problem is, I want to replace the current unfused isolator outside the bathroom door with the switched FCU - but the current setup is just switching the permanent live. Neutral and earth are connected via a JB in the loft.
So is it okay to go ahead and replace the existing isolator switch with the SFCU? Or is there a better way to do it?
