I would like to install an on/off switch for my electric water heater
at the cottage instead of using the breaker to turn it off or on, is
there any reason I should not do this? What type of switch should I
use? I have an older 40 Gallon water heater using a 2 conductor (black
and red) #12 copper cable.
No reason not to, providing you can find a switch with sufficient
capacity --- at least the rating of the breaker supplying the
I would suggest using an air condx disconnect box since they are
very cheap ahd have high capacity.
If you have a problem finding a switch with the proper rating, you
could just install another breaker at the desired location, since they
are cheap and rated appropriately. The disadvantage is that they
don't have as many cycles in their lifetime, but that shouldn't be
a problem for you, and they are easy to replace...
Just a couple ideas.....

Product called "Little gray box", it has a timer in it that allows the hw
heater to be turned off when no need for hw. It has adjustable timer 'on,
Or leave them out, and you have a switch to turn it on or off.
About $20 at big box stores in the plumbing section.

You would need a "double pole" (4 connections) switch rated for the amperage
of the circuit (30 amp?). Also there is a water heater timer. Links below...

7 day water heater timer with manual mode and on/off switch...
Thanks for your help, could not find the switch or timer at the Home
Depot here in Ottawa, Canada? Don't know if our Electrical code does
not allow them? But did find a shut off safety box with a pull out
switch you insert one way for open and the other for closed, it was
under 15 bucks, even though it was a little bigger than I needed it
