you may be going in the wrong direction.
i just installed a 3 kw 240 v uk swan teakettle in my kitchen, removing
the 13 a fused plug and wiring the line cord into my 3-wire range with
spade disconnects. (how many nec violations is that? :-)
it boils water in less than a minute with five times the microwave's power
and twice the efficiency, then instantly turns itself off.
ge makes a wimpy 1500 watt 120 v version, $30 at wal-mart. at 6 kw on 240 v,
(the grid is 249 v at my house), its 6548 watts might boil a cup of 60 f water
in 3600x0.5(212-60)/(6548x3.142) = 12.4 seconds, within the dual 40 amp range
breaker capacity, altho that might fill the kitchen with huge clouds of steam
and shorten the life of the heating element and burn out the pilot light.
and... a halloween "crash-a-witch" hugging a bundle of burned-out flourescent
tubes would look cool hanging from a nylon rope over the 25 kv transmission
line on the telephone pole above my mailbox, close enough to the line to glow.
nick, ee gone wrong.
