[QUOTE="Phoenix, post: 393526, member: 8133"] It just seems like the current set up is asking for trouble. 3x 2.5mm terminated in a plate switch (with terminals which probably are not great) with multiple cables per terminal carrying 13A for hours on end after it has been forced back into a box I think if I was asked to wire such an arrangement, it would end up as a feed straight to the water heater location from the board. Local DP isolation, then the load switched by a contactor, with the coil being operated by 2 way switching set up using ordinary light switches and protected by a 6A breaker fed off the supply coming into the contactor. If neons required then extra cores and a MK grid plus arrangement for the switches I wonder how difficult it would be to convert the OPs set up to this [/QUOTE]
