I need to install a pump in my airing cuboard for my new mixer shower. The instructions says that it needs to be wired to a 3 amp fused switch, my question is there is already a fused 3 amp switch in the aring cuboard that is for the central heating control box (or what ever it is called), can I just wire the new pump into this existing switch or does each piece of equipment need its own fused switch????
The other question is the instructions for the pump also says that an RCD with a trip rating of no more than 30mA should be included in the circuit. I was thinking of using the RCD that is on the electric shower that will soon be replaced. But I cannot see on it anywhere what the trip rating is, there is a value of 40A and some greek letter then 0,03A 240V made by Hager.
It says it has a Inter Differential x U740 uI 20066.
What should I be looking for to know if it is suitable????
Thanks
