I have just installed a "CUGAR1" garage unit in my shed. It consists of a 40amp RCD, a 6 amp MCB and a 16 amp MCB.
I brought the incoming power from the house on a 2.5 mm twin and earth. I have wired the live into the RCD (it already had a neutral cable going to the neutral bar), fitted the busbar between the live point of the RCD and both of the MCB's.
I have wired a striplight to the 6 amp and a ring main of 13 amp sockets to the 16 amp MCB.
When I turn the light on it trips the main switch and when I plug something into any of the sockets its OK until I try to use it then it trips the MCB.
Can anyone tell me what I have done wrong please.
Thanks
