More basic advice please - need to check if my gut feelings are right!
SWA from house to garage. 3 core SWA at house board, 2 core at garage. Presume there is a joint somewhere. Plan to re-use a plastic 2 way RCD CU in the garage.
I have been told to dress the cable so that a few cores of the SWA will reach the earth bar in the CU (sleeved of course) and trim and insulate the others off. I don't think this is right as I can't rely on the earth being continuous - not knowing how the joint was made.
I'd have thought that either
a) a terminal box with a gland and banjo should be used or
B) all of the sheathes should be connected together (could group in three braids) and either put directly onto the earth bar.
Am I being pedantic or is my gut feel right?
Would the split off a few SWA method be acceptable if there was no join in the cable?
Thanks
Dave
