On demand water heater installation
does anyone know of a device that will turn off one circuit when another is turned on? I would like to disable my a/c when the on demand water heater is turned on. this will keep me from popping break...

A 20 Amp SPDT (3 Way) switch will do the job for you.
Not high tech and cheap (under $10.00 for parts).
