Hi, Im wanting to ugrade my old 8.5kw shower to a 10.5 kw shower. Several years ago I replaced the shower cable as it had been run outside the house in orange MICC cable with 10mm cable so the cable to the shower/consumer unit is ok and about 15m ish.
My fairly old wylex consumer unit, old brown looking thing with about 8 fuses to the left of the main switch and a 45 amp fuse to the right of the main switch.
Now I now Ive got to fit an enclosed 45amp rcd adjacent to the consumer unit but Im just wondering what fuse to take the shower from?
At the moment the shower is connected (via my new 10mm cable) to a 32mcb but the largest mcb that will fit the board is a 40 amp mcb, can i replace this fuse and holder with a 45 Cartridge fuse and carrier in place of the current 32amp mcb, will the bus bar in the cu be able to handle the increased load ??
Cheers.
