Hi,
I need to install a dedicated circuit to connect my immersion heater. I have a spare 16amp RCD on my Dist unit.
I want to put the 20a DP switch in the lounge, connected to the RCD, and to a dedicated fused spur with a neon outside the cylinder cupboard, to indicate when the heater is in operation. The spur will be connected to the Immersion heater with heat resistant cable. The spur will also prevent accidental switching of the heater on by children, by throwing the switch off, thus isolating the heater from the DP switch.
Do I need to use 1.5mm or 2.5mm HR cable to the heating element?
Is it okay to use ordinary mains cable from the spur to the DP switch in the lounge and from the DP switch to the RCD? Will the 13amp fuse in the spur be okay, or do I need to replace it, (with what rating?)
