Product Overview

The WH40 Mechanical Water Heater Time Switch regulates electric water heaters. Utilities in many areas of the country offer two electric rates for residential or commercial customers. One rate has the regular daytime rate, the other is the 'off-peak' rate. This 'off-peak' rate provides customers with lower priced electricity during the nighttime and weekend periods. This time switch allows the customer to shift electricity use into the 'off-peak' time periods in an attempt to save utility costs.
  • Double pole, single throw
  • Convenient external override switch
  • NEMA 1 rated indoor steel enclosure
  • CSA listed
  • For use in residential, commercial, industrial, military, and school applications
  • Additional sets of trippers are available - #156T1978A

The Intermatic 40-Amp time is perfect for our water heater and pool chlorinator needs. We used 2 of them. Wiring is straightforward, and available knockouts met our needs for interfacing with conduit.

Accidentally ordered different brand - my error. Upon realizing this, ordered the Intermatic to replace an old one. Installation was literally a snap. No rewiring needed, after unhooking the wires, just snapped out the old unit, snapped the new one into the older housing and re-hooked the wires. Thankful that in 30 years, the units were virtually identical because I was not looking forward to having to mount the replacement on a concrete wall and re-run new conduits, etc. Thanks to Home Depot for continuing to stock an old, reliable brand. And further thanks for the ease of ordering via internet, so all I had to do is walk in and put my order number into the locker. No hassle either in returning the other brand that I didn't need. This is especially helpful as I get older and less able to physically walk up and down aisleways.

Overall I like the timer. Two things though. I have used one at another home for eight years with no problems. The only criticism I have is the timer is noisy!!! The old one was noisy and the new one I bought last month month is just as noisy. You can hear the timer running. The second thing is the ground wire connection requires the wire to be bent around the screw. On the other terminal connections you don't have to bend the wire. You can leave the wire straight and insert it in the connection and tighten the screw. Thanks

Poor quality and insufficient warranty / support
I replaced the existing Little Grey Box because the trippers stopped working (timer would jam on the tripper). The next one lasted two years before the same thing started again. Support said it was a motor failure. I replaced the motor with a new one from Granger. The new one did not help the issue. I am replacing the box with a digital one. That's three boxes in two years. At minimum, Intermatic should have sent me the replacement motor.
