1mm T&E on a 16A MCB - doesn't look or feel right!

C2 it, ignore the software.

To be fair as well a typical immersion heater is 3000 watts so pulls 13amps.
The 16amp mcb won't need to provide overload protection to a fixed load so will only need to protect the cable for fault protection purposes.

I know I shouldn't be worrying about a solution, but the easiest way to resolve is to put the immersion on the ring! I do realise that its not recommended (not prohibited though) but as its not used much (if at all) I think this should be OK.

Table 52.3 in bs 7671 does say that power circuits are to be wired in 1.5mm as a minimum or for a specific appliance is specified by the product standard so depends on manufacturers instructions as well

That I think clinches my dilemma - C2 it is!

I'm not, but I can't assume anything either way.

I was already to make it a C2 until the software I used highlighted that 1mm T&E using Ref C was ok!

The software isn't going to get screwed if it goes bang! You are. If you're not happy with it, then C2 it

Excellent spot Ian.

Which software are you using?

 

[Hellmooth]

1.5mm minimum for power?

Ahhh just seen other post mentioning that already!
