RCD trips only when powering a load

[kwil9610]

Hi, hope some can help me!

I recently had an electrician install electrics outside in the garden. He installed a consumer unit in the shed to feed lights and sockets etc. He fitted everything needed in the garden but when he started to fit the armoured into the house he ran out of time and said he would returm at a later date. Never came back! Anyway, tried doing the rest myself by drilling through wall, connected the armourd cable t9 the consumer in the correct manner. Noticed that there was no available slots left of the rcd side of the cu, so put it on the other side. Power the main cu up and everything ok until I plug something in to the sockets outside or turn on the l8ght swich

Is the neutral wire connected to the CORRECT neutral bar in the consumer unit?

Also, the armoured cable is probably 3 core. Check the same colour wire has been used at each end for L, N and E.

I hope that you did not pay him anything

Its the RCD in the outhouse that trips, yes?

If so, the response above tells you the solution, or post a pic of the offending wiring.

Thanks for reply There's only one neutral bar in the consumer unit. Iv checked all wiring and all appears to be correct. The RCD that trips is the one in the house consumer unit btw. Its only when trying to power something that it trips

There must be 2 neutral blocks in there.

As the circuit is connected to an non-rcd way in your house CU, please state if there is a 30mA RCD in the CU in the shed.

And pictures of the inside of teh house CU, as requested above.
