Do I need a switch for an electric water heater (residential) where the panel and breaker for it is 8' away in the same room?

(B) Appliances Rated over 300 Volt-Amperes or 1⁄8 Horsepower. For permanently connected appliances rated over 300 volt-amperes or 1⁄8 hp, the branch-circuit switch or circuit breaker shall be permitted to serve as the discon-necting means where the switch or circuit breaker is within sight from the appliance or is capable of being locked in the open position. The provision for locking or adding a lock to the disconnecting means shall be installed on or at the switch or circuit breaker used as the disconnecting means and shall remain in place with or without the lock installed.

If the breaker is within sight and 8' then no other disconnect is needed

Had an inspector try to get me to put in a disco or lockout. He said" someone could build a wall between the panel and the water heater". I didn't comply.

We are not required to provide disconnects for residential water heaters, only commercial
But the NEC requires it so you are in violation every time you wire one without a disconnect.

I'd just like to know how many horsepower "1⁄8" is.


I'm thinking of adopting that into my job lingo.

"Hey, bring me over a one and frazzle 8, and be quick about it !"

Or, does Arizona exempt residential water heaters?
If it has a written amendment you are correct but my bet is that they don't. This area also has a lot of things they allowed but the NEC does not.

When roughing in houses we put metallic clips on breakers that feed hard wired equipment such as dishwasher and hot water tanks. This provided the lock out means and eliminated disconnect means. They were quick and afforable. This would even apply for HVAC units. I feel commercial equipment is another story.

Metallic Clips ?
Are these those clips that keep someone from shutting a breaker off or a type of lock out device that one can install a padlock into?
If it is not a permanent device that will allow a lock then it is not code compliant
