Darren,
The heaters each require 220VAC at 8.7A and as many as four of them will be running at any one time. I've split off 110VAC inside the controller box to power the PID temperature controllers, air pump and the power supply. The temp controllers and air pump are switched, the power supply is not but it has it's own power switch. Everything is thoroughly grounded, including all of the tanks through the immersion heaters. I don't like surprises.
