Question

I have a Truma Ultrastore rapid GE water boiler in my caravan (Dual elec heat version). I want to extend the control for the 240v further away from the boiler - do you have an extension lead for this (3 m should be fine).

Answer

Possibly best to install a terminal box at the site of the existing switch and run a length of 1.5mm 3 core 230 volt cable to the new switch position.
