I don't know if there is a spare I'll check and see if one can be swapped over just to test it. Should I turn all the CU off and do I just pull the breaker out and click back in to test with a different one ?
This would at least tell you your F.L.C. and then do a installation restance test this will rule out a earth fault.no. you turn off main switch, then move the circuit wires to a different MCB. if it's on the other RCD, you need to move the N to the appropriate N bar.
a better idea would be to clamp the L coming out the MCB and see what current is flowing. for this you'd need a clamp meter.
thats rulled that out then!Outside lights don't have sensors. Am in toolstation now and with pick up outside bulbs and check them and report back later tonight.
Maybe because it's the Christmas holidays?Sparky that wired all house now not answering his phone.
I will get building control to chase him up and let them know the wiring needs independent testing through them as I feel it is unsafe for me and my 5 young children.
