Been called to have a look at a shower which is being replaced.
The shower which is going in is an 8.5kw but the cable goin to the shower is currently a 6mm2 t+e run in trunking but protected by a 40 amp rcbo, which according to the on regs is not allowed as running it in this way it will only take 38 amps.
So should i go ahead and change the cable or just down size the rcbo, the cable run is about 4/5m long.
