Hi All, i turned my electric heated towel rail on for the first time in a while yesterday, and it tripped the RCD.
The towel rail is powered by a switched FCU spur taken from the cooker supply cable. (junction box and swithc outside bathroom).
After i flick the switch, it takes approx 30secs for the RCD to trip. The fact that it doesnt happen straight away leads me to believe that its the heating element at fault, rather than the wiring.
To confirm this, my plan is thus; wire the towel rail up with a plug, and plug it into an RCD protected socket. If it trips, then bingo, its the element, if it doesnt, get the BiL round to have a look (he installed it).
Does this sound like a reasonable plan?
