i'm new to this forum and ask that you all bare with me.
i intend to install a new shower, a triton ivory III 9.5kW electric shower. the cable run will be no more than 10 metres long running along a void area. the existing consumer unit is of the older type..ie...it uses the old wired fuses. there are six fuseways the highest rating being 30 amp. there is a spare. the shower is a 9.5 kW Triton Ivory III. i would be obliged if someone could advise me as to the wether i can use the spare fuseway on the CU using the correct fuse wire ie 40/45 amp?...what cable thickness to use? and will i need to fit an MCB or RCB?......and what amperage should the RCB / MCB be?... i know i need to fit an isolating switch between the CU and the shower unit. i would be grateful for any advice you can give me. thanking you in advance.
curious.
