Max immersion heater on 60A circuit?

[brixtonia]

Hello,

What would be the max Wattage immersion heater I could comfortably install on a dedicated 60A circuit?

Not DIY but trying to figure out some options before speaking with contractors.

Cheers!

14 kWatt. 240 x 60 = 14,400. watts. that size of heater would be best on a 3 phase supply. then it's only 20A/phase. and of course, 2.5mm cable as opposed to 10mm.

Thanks ?. That's what I'd come up with but wasn't sure if it needed extra capacity, a bit like a pump starting up.

No, an immersion heater is normally a purely resistive load.

OP it depends what the supply voltage is
