tank water heater service disconnect?


Recommended Posts

sorry. I see postings that say a electrical service disconnect is required for tank water heaters in homes. Not clear about if it is new construction or replacement of an existing heater in an existing home.

But what about similar "electrical things" like dishwashers, or trash compactors, do they need a service disconnect

ps English IS my first language.

All appliances require disconnects, not just water heaters. Like Jim Port said, in *some cases* a cord & plug can be the disconnect. If a breaker is in sight, it can be the disconnect. If it's out of sight you can *sometimes* use a breaker lock. You can find the details in the NEC at 422.30 through 422.35. The bottom line, though, is that every appliance needs some kind of disconnect.

I know that. But your post was unclear anyway.
