I am currently installing an airbath in my bathroom
The kit contains a heater at 13 amps and a blower unit at 5 amps.
I wanted to run a 2.5mm twin and earth from my consumer unit to my bathroom, to 2 fused spurs one with a 13 amp fuse and one with a 5 amp fuse for further protection to the bath kit, and protecting the cable with a 20 amp RCCB.
would i need to use the rccb if i have a split consumer unit with a 30maA rcd in it. How does this work, does it protect the bigger mcb's for the sockets etc. I have 1 spare way and i think its on the smaller mcb side?
Any replies would be much appreciated
