The pump has 3 wires coming from it, brown (single phase line), blue (neutral), yellow/green bi colour (protective earth), can i simply install a plug to the end of the wire with a 13a fuse and plug it into a socket? or do i have to fit isolator and wire it to the mains? Its going to be installed under my bath, so the wire would be fed to the mains in the loft. I hope its the easy plug option lol. cheers
