I've been renovating the G/Fs bathroom this week, upon going to turn off the shower supply, I found that it was supplied from a really old fuse box, as well as looking like it is a spur from the cooker supply. There are no RCDs anywhere in system.
To make the shower a little safer, I would like to fit a RCD to it. Would something like this be suitable:
I presume, to fit this, I would disconnect the supply to the pull switch, fit the supply to the RCD, then the output to the pull switch?
Ta for any thoughts. Alan.
