Hi. I have just wired up my shed and an outside lantern.
I have run a circuit using Swa from a new MCB on the house to a New consumer unit in the shed with an RCD and 1 16A MCB for a socket and 1 6A MCB for lights. Because the shed is 50m away, I have not connected it to the house earth but have used a new earth stake at the shed and earthed it there.
On switching on the house MCB with the Shed RCD on and MCBs on all is ok.
Once I start to draw any current the appropriate MCB and RCD trip in the shed CU. IF I switch on a light the 6A MCB and RCD trip or if I plug something into the socket and switch on, the 16A MCB and RCD trip.
All wiring looks ok. Any ideas?
Many Thanks
Steve
