Yep, and if you can't bring the new leads down from the top of the tank
because of that foam insulation, I don't see why you couldn't use a hole
saw to make an appropriate size opening adjacent to the lower
thermostat's cover plate. You could install a standard cable clamp there
for that feed from the off peak meter.
I'm presuming your heater DOES have a lower thermostat and cover plate,
but the way they're cutting back on stuff fer all I know they've
figgered out how to get by without 'em already. <G>
