Guys, i have added a 32A MCB to my main consumer unit so I can add outside lights and posibly a hot tub at some point. I have wired it to an MK IP56 double socket with 30A integrated RCD outside the house.
In the short term and to get some lighting in my shed, I thought I could simply take the mains for the lights from one the two sockets in the MK unit. Simple I thought except that I am tripping the main RCD in the consumer unit everytime I switch on the light in the shed. The 32A MCB is not tripping but the main 60A RCD is.
Is it something basic I am doing wrong? It's driving me mad at the moment.
Many thanks
Jonathan
