When installing a Mira Sport 10.8 kW shower heater and providing 10mm T&E from a 50 amp fuse & RCD at the meter, is it acceptable to use 6mm T&E for the final section from the pull switch to the heater?
This final section would be run in plastic trunking along with the copper supply pipe on the surface of the tiles from ceiling level.
Also if copper tube is used for the water supply, will a seperate earth bonding cable be required in this trunking?
I ask all this because of the extra space that would be required required in the trunking.
Many thanks in advance for any help and advice.
