Hi, I replaced a 13 a RCD spur today as customer had overloaded it and melted in the fuse holder. It supplies a garage that they use for doing art work and they had 2 heaters on it and a kettle now and then and wondered why the fuse was blowing. I bought a new one at QVS as it was nearby, admittedly a cheap ish one. I put the supply back on after fitting it and pressed the reset and all good. However, after resetting after pressing the test button there was a large bang and some smoke. There were no shorts, all connections good and no load switched on in the garage. The fuse in the spur did not blow , nor did the one in the consumer unit. I can only suspect a faulty unit. Has anyone else had this problem.
Thanks in advance.
