Hi I'm running a new consumer unit in my shed for 2 lights and 4 sockets. Would I be ok running 6mm swa cable from a 40A mcb from a duel rcd board thanks Simon

Unless the shed is next to the house, and even then I'd reconsider, I generally wouldn't RCD the SWA. The SWA doesn't need it, but the final circuits do; give them their own RCD or RCBO in the shed CU. Re earlier replies, Distance (volt drop) and demand ( design current) and de future (up grades) will help determine conductor size.

How do you know the SWA doesn't need RCD protection based on the information supplied?

Follow the link Geordie gave you. This subject is getting tedious.

This shed /garage saga never ceases to amaze me on this forum, do we actually have electricians in the UK these days, or are they all electrical trainee's that haven't a bloody clue what they're doing!!

It's a good question engineer54!

I would say that generally about 90% of the recent alterations I encounter (brown&blue cables) are absolute carp.
