Hello All
A friend of mine has just had a CU change from an old re wireable fuse box to a new Dual RCD board i didnt do the job for him someone else did.
with the old board in place the immersion heater 3Kw worked now with the dual RCD board the immersion heater trips the main RCD the immersion heater runs though a timmer and is supplled by a 20A radial in a swiched fused spur with a 13A fuse
I thought this was to boarder line as 3Kw will pull 13A i would be looking to run off the radial a 20A DP switch.
Could it be that the 3 Kw element is slightly breaking down a is sensitive enough to trip the RCD.
Havent looked at the job just going by what ive been told.
Any thoughts
