That's going to be a big cable to my 3kW kettle and heater ;-)
Even bigger for 10 kW of storage heating... 40 odd amps at 230 V for
a few hours makes the tails warm. The 200 A required for a 50 V
supply is getting hard to handle.
For a H&S viewpoint, an ELV domestic system would save around 20-25
domestic deaths and around a third of a million serious injuries from
electrocution every year.
