I will be installing a three phase, 120/208 volt 40 amp circuit for a restaurant coffee machine. My questions are: do I need to have a disconnect for this unit? (FYI: electrical panel is 25' away not in sight and no space for a disconnect). Can I hard wire the coffee machine without disconnect. Thought about a cord and plug but, the plug and receptacle would have to be a five wire because the coffee machine needs a neutral. Any thoughts or ideas would be appreciated.

Thanks

Per 2008 NEC section 422.31(B), as long as the coffee machine does not contain any motors rated more than 1/8 horsepower, the disconnecting means can be a circuit breaker that is lockable in the open position, as long as that locking means remains in place with or without the lock installed.

So basically I can hard wire the coffee machine and use the breaker as a disconnecting means? I don't think the coffee machine has a motor on it. Just three, 5 kw heating elements.

thank you. I will install a breaker lock kit. Is it acceptable to have the panel door lockable instead of the breaker lock kit?
