2.5mm lsf radial from 20a DP switch

[Bigcheese0]

Hi

Im Looking for some advice on compliance as its a bit of a gray area

Kitchen currently has 13a FCU fed from ring main and 2.5mm lsf to single gang skt for washing machine.

Want to change this to

20a DP switch and spur off the single gang socket for washing machine and fit second single gang skt for dishwasher.

Reason for not fitting new FCU and separate supply is its a brand new house and would have to destroy tiles.

I realise the current capacity of the 2.5 is round 20a but the washing machine and dishwasher are no where near pulling that even with both heaters on at same time and taking diversity in to account would imagine it is unlikely to ever have both machines on the heating phase at the same time.

Would this be acceptable ?

Yes back in the day it was fine but I ain't been on the tools in a long time and not domestically.

So if its acceptable for an EICR to have a socket under the sink can it be fed directly from the ring via 2.5mm radial?

Yes, as long as it's a single or double socket, but if it's a double, the question arises as to whether it's acceptable to plug in two appliances with a combined intermittent draw that might exceed 20A.

If an occasion occurs where the current draw is likely to exceed 20 A, I extend the RFC into the cupboard into a dual surface box and fit two single sockets side by side

Switched Single socket under sink fed by 2.5mm lsf spured from double socket above w/t.

Would this be OK for an EICR

Is it fed from a ring or radial? What rating is the circuit protective device?

Hi will be of 32a rcbo

 

[brianmoooore]

As long as the double socket above is part of the RFC and not a spur off of it, then that is all compliant.

Yes it's from the rfc and will mount switched socket below the shelf in the sink unit so as to limit any chance of water ingress
