I'm bidding a job where I have to install hand dryers in bathrooms. All the bathrooms where I've been, I've never seen a service disconnect. Looks like one would be required, especially in a setting where the breaker may be in a far remote panel, such as the one I'm doing in a large clinic where there is several thousand square feet of space. Maybe it's not required?????? Thanks Steve.....
422.31(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 disconnecting means where the switch or circuit breaker is within sight from the appliance or is capable of being locked in the open position.
Just make sure you provide a lock out kit on the breakers feeding the dryers.
Talk to the breaker suppler you can get a lockout kit made for the breaker that stays mounted to it.

iwire, Thanks for the response, I went and got my trusty code book out. I think mine will fall under the one above the article you gave me. Mine will be under 300 volt/amperes or 1/8 Horsepower, so the disconnecting means can be the branch circuit overcurrent device... Thanks for the help. Steve
