RCD Tripping

[leevis]

Hi
Hopefully someone can help me, I have a new shed and the previous one had power to a consumer unit inside the shed, there is a join outside. I have moved this and connected it back up but when I flick the shed fuse on the main rcd in the house it trips, none of the consumer unit in the shed is switched on yet.

I am guessing that this would point to a problem maybe in the join? or the cable itself? if the main fuse in the cu is still off this would be a problem before it right?

Just trying to troubleshoot here,

Thanks

Tell us more abut the joint, what sort of cable, how many wires, anything that may offer a clue.

We may ask for some pictures too

It could be something simple as a dead short. As above, more information and photos of CU in the shed and definitely the rcd tripping?

Make sure the main switch is off in the shed and try again?
