Yes .My dad taught me about the cost when fiddling with the thermostat.
Why people bother with those digital timer thermostats.They are useless to me .The same with the refridge.Keep it cold and leave it at that setting.

Was that firm in Canada, because 600 volts isn't very common in the US. Their industrial and large commercial is 600Y347 volts, three phase.
I wouldn't doubt that 480 volts, three phase is available from the poco, there, because of the close proximity to the US, for US built equipment.
