6mm kitchen radial sockets with cooker on 40amp MCB

[littlespark]

I have used Wago to extend 6mm cable no problem

The issue is still you have sockets on a 40amp mcb and don't know the rating on the sockets

With my earlier suggestion of joints in the boxes and a pigtail onto the socket, the socket terminals will not be taking the full load of the circuit, the joint behind will.

Some sockets are easier with bigger wire than others, Crabtree comes to mind.
Any reason you can’t change the breaker to a B32 and improve the current terminations?
I know 6mm is a bit of a pain but it’s usually doable.

Thanks guys, I think I will advise the customer to change the 40A to a 32A MCB as concerned about overload within the sockets, the only issue there maybe constant tripping due to cooker, etc, if a short initial surge :/

You have to try really, really hard to trip the MCB with a cooker. Most folks would baulk at the electricity cost now in any case!

Slightly OT , but since getting my air fryer I have probably used my actual oven twice
