Hi,
I have electric underfloor heating in my living room/kitchen (one cable, wattage unknown) and when switched on, the spur switch (with a 13A fuse) on the wall becomes very hot, particularly the fuse section, and there is a bitter/fishy smell (like something melting). The electric board for that room/cable has a 16A circuit breaker and a 20A contactor.
I also have underfloor heating in other rooms, and the spur switches become warm after a while but not hot.
I am thinking that maybe the heating cable in the living room/kitchen uses more current than other smaller rooms, and therefore could exceed 13A, or the heating is somehow getting transferred to the switch.
Maybe the spur switch should be replaced by a 20amp double pole switch?
Any ideas?
Thanks
