Most any hardware store will carry a timer called The Little Gray Box.
The Little Gray Box Water Heater Timer - Intermatic Model WH40
Handles 40 amps. Is wired for 220 but is easy to wire for 120.
killerweed420 Reviewed by killerweed420 on . Timer contactors Heh Do many people use these? They are only necessay if your using loads over 600w + for lighting as apparently household timers are simply not designed to handle the power loads.....and i recently discovered this to be true when bust my contactor and decided to give it ago without one, and for sure it frazzled my timer (digital) and the light times were all ova the place:upsidedow Rating: 5
