A job I'm starting a new build bungalow has been specified 16mm twin and earth for 10.5kw shower complete with a wall mounted isolation switch outside of the ensuite, which is a stud wall!
Oh the joys.
Apparently 3 layers of insulation are going in so looking at reference method 101 even 16mm twin only pulls 46 amps reference method 101.
At 10.5kw I'm looking at a loading of 43-44 amps so the 16mm will be able to handle it.
I need to consult the builder and maybe request some boards are fixed above the insulation so a 10mm can be clipped above the insulation.
They won't budge to a lower rated shower tho.
Doubt I'd even manage to fit a 47mm box in the wall as the studs are only about 50mm deep
I'll get round it as I really don't want to be installing 16mm but it's not mine or my company's specThat is a narrow stud
Thankfully always 4x2 with the joiners we work with.
Would not like to terminate a 10mm in anything less than a double 47mm box.
To be honest don't like wirring showers fullstop![]()
I've used them on 10mm never on 16mmDon't like using them, but could u fit a 47mm faster fix box to give u that extra room.
The spec is deta accessories.So true DW. First one I checked was Crabtree 50A and they won't accept bigger than 10mm2.

Can only think running and terminating a 16mm2 T and E would be complete barsteward16mm for a bloody shower? bloody madness. these insulation freaks need to work round us and keep it away from cables. not vice versa.
