I have two corroded wires on my Triton Opal II shower, one is the brown (earth?) terminal block wire, and the other is the brown (earth?) wire that connects the PCB to the termal cut-out, it looks like a streaight forward replacement job but I don't know the voltage of each of the two wires and trips to electrical shops have so far proved fruitless.

no wonder,brown is live,green and yellow is earth,for gods sake dont mix them up,the voltage in this country is 240 v ,the cable you need is 6 mil .
