Anyone hear of a code requirement for a disconnect on a hot water heater?

You betcha. Within sight and within 50 feet. Sometimes the breaker in the panel is sufficiently close to qualify.frogneck77 said:

I knew I would get the usual treatment for asking a dumb question, but I couldnt help it. In the 13 years Ive been wiring houses Ive never had to install a disconnect on a Cold water heater.Conversing on this forum helps me take my brain out of autopilot quite often-Thanks for the laughs and all the great info-I really respect all of your opinions,the occasional spark of wit is entertaining as wellstickboy1375 said:Yeh, its an appliance... :grin: And its not a hot water heater, if the water is already hot then there is no need to heat it..

See Sections 422.31(B) & 422.35 of the 2005 or 2008 NEC. The NEC permits a lockable-type branch CB (of the ?indicating type?) to serve as the disconnection means; even without being ?within sight? (and beyond 50 feet).

Ill admit it, Im one of those guys who doesnt pull the code book out very often.I still reference the 2005 in a pinch because thats what I took my E1 and E2 tests on. I come on to this forum to brush up on code and ask questions about anything that comes up in my day I think you guys can help me with. You guys rarely disappoint,w/info and laughs

I like breaker locks a whole lot better than installing a small disconnect (Or I have seen some install a 3 wire dryer outlet).

I highly doubt a cord on a water heater is legal...

I've seen that too, but that's not legal. A 3-wire dryer rec is 120/240 ungrounded, and for a water heater you'd need a rec for 240 grounded.Minuteman said:

I do not undestand.
What code would you cite?

Marc, what difference would that make. Isn't the 3 wire dryer ground terminal grounded to the metal of the receptacle?

I would go with that the Water heater is not listed to be cord and plug connected... :wink:
422.16 Flexible Cords.

I don't think Marc was talking 422.16.
BTW are you sure they are not listed for that, or like me you just never did it that way?
Insta-hots are solder in place and have cords. :smile:
