Extending a circuit

[DanGB]

Hello all,

I need to extend a ring cirucit in the middle, basically it comes out of the floor and need to make part of the cable longer.

I was going to use something like this:

or

My question is, these are rated to 30A, but the ring circuit im using (kitchen) has a 32A breaker. Are they ok to use, or do i need to find a beefier juntion box?

Im reading conflicting answers on this. Its odd as Junction boxes seem to be 30A or way over that, nothing in between.

Thanks.
Dan

Would be fine, on a 2.5mm ring the cable only could be rated 27A if clipped to the wall anyway.

They're fine. Don't forget that there are two cables in a ring.

Be aware that those junction boxes must remain "accessible" for inspection, especially the chock-box ones - i.e. cannot be hidden away.
