Hi,
I have a new style MK fused switch which is connected to a standard gas boiler.
I'm trying to sort out the electrical connections to it and the boiler in readyness for a new boiler.
The problem I have is there are 5 connections on the back of the switch, plus the earth connection. I understand the L + N Feed in and the L + N Feed out, but what is the 5th connection for?
Any help/pointers would be appreciated,
Thanks,
Dave
