Just a quick one, all my books are in college.

Is it acceptable and up to current 17th to use 16A on a radial. Wired in 2.5 T&E, short run (8M) with 3 sockets.
I have used 20A in all other flats (6 of), but got to the last 2 flats and ran out of 20's, so my colleague put 16's in. I'm 99.9% certain it is 20's, but is there anything wrong with downgrading.

Just to settle my little dispute.

Cheers Guys

Id stick with 20 for radial and 32 for ring as sockets you cant be sure what they will supply.

Agree with that^^

Also, why not just change the MCB's at the suppliers for the correct ones??

All having a 16A MCB means is that the circuit will not be able to supply as much equipment as a 20A. Nowt wrong wi that but like the lads have said a 2.5mm radial will be more than happy on a 20A so I would swap them out also, gives the client a bit more scope.;)

Thanks guys.

I knew I was right with the 20, but he is not wrong with 16 either under current regs.

He is a top guy at 74, no 17th edition but a fantastic mentor. I know what it will have been.
