Hello. Would be grateful for any advice on the following;
I am upgrading my hot tub, the last one being a 'plug and play' type (1.5kw heater). My new tub has a 4kw heater.
The existing wiring is a 10m run of 2.5mm flat twin and earth, not insulated or buried (hot tub is indoors) from a 16A mcb from the consumer unit on the RCD side, through a rotary isolator and cable goes through wall into the spa room.
My question is, should i upgrade the wiring or will this suffice for my new 4kw tub?.
Thank you.
