Hi,
For a long time I have had an RCD tripping problem with my 2 Storage Heaters (SH) each connected to an MCB on a CU with 2 MCB's and one RCD.
Rightly or wrongly, I have now come to the conclusion that the much older 1.7kw Tricity SH is the problem. I think that when the Tricity gets fully charged it then does something that trips the RCD (not its own MCB or the other SH's MCB but the RCD).
This means the other SH a 3.4KW Sunhouse (3 years old) which is also on the same CU is cut off from the supply. My solution has been to never increase the manual dial on the Tricity past 5 (the range being 1-7).
My reason for the full charge claim is that when the Economy 7 (7hours 30 mins) kicks in if the Tricity is above dial position 5 about exactly 7 hours later the RCD is tripped. Keep it to 1-5 and keep the other SH on any dial and this won't happen.
Can you tell me why?
