Okay, now I'm just getting confused. When I did my ringing round today, one of the electricians asked me what I currently had and he said I needed an "RCD pull cord" in a sentence as if they were the same thing.
All I know is that I don't have a pull cord switch in the bathroom and the shower runs hot unless I go downstairs, open up the meter cupboard and flick the switch on the MCB unit to off - at which point the shower runs freezing cold.
If it's connected to anything else, then I've missed it, so it must be really small or hidden somewhere!
So do I need an MCB, an RCD and a pull cord isolator thingie and I'm missing things that I should have? The shower was installed before I bough the house...
