Gotta love the UK domestic ring main system with 13A+ @ 230v = 3kW per socket and a total of 32A per ring = 7.3kW as standard on tap!For the supply of mine, to deliver the rated 50 volts at the rated 50 amps=2500 watts, I would need quite a lot mre than available at my 12 volt outlets with 15 amp circuit protection in this old house. Only a very few 20 amp outlets. I don't need more in most places.
