Tomorrows job is to provide a power supply for a jacuzzi bath that a plumber has already fitted. He has removed an electric shower to do so but the circuit for the shower is still there, terminated at a 45a a switch on the outside of the bathroom. The plumbers suggested I can use this to feed the bath as its redundant for the shower. He wants the connections to be under the bath which will have a panel on the side which can only be removed by the use of a tool so under the bath will be out of the 'zones'. My question is do I make the connections with a fused connection unit or a plug and socket connection. The bath only needs a 5a supply.
