Contactum MCB

Stevo88 · Mar 14, 2012

Hi, I will be upgrading a shower shortly. The existing unit is 7kW and I'm fitting a 9kW unit. Does anyone know where I can obtain a Contactum 40A MCB from. I can't find any supplier that stock the type on the photo (9040B). Or is there an equivalent that fits this CU ? (Contactum P12/80N)

are you upgrading the cable also or is it suitable for 9kw already...!

try TLC direct

Thanks Durhamsparky, I tried TLC online and they've got one! BTW I will be upgrading cable to 10mm*. Another quick question is why do so many people seem to fit a separate shower consumer unit? Is it just due to lack of capacity /RCD?

normally due to the fact people don't have RCD protection on the current CU (probably a old wylex 5/6way db or it was fitted by a monkey and he saw the sign in B&Q say "shower fuse box" complete with 50A MCB

also works nicely for the "garage consumer units" FFS!!!
