6. Equipment
An appliance is rated 1200VA at 208 volts, three phase. It is a cord and plug connected. The cord plug and receptacle are not accessible from the location of the appliance. The disconnecting means for the appliance is the circuit breaker located in the panel. The panel is installed 65 feet from the appliance and can be seen when standing at the appliance. The circuit breaker can be locked in the open temporarily by use of a breaker lock out supplied by the manufacturer. Is this an acceptable installation?
Copyright 2005 Ted "Smitty" Smith

7. Equipment
No   requires the cord and plug to be accessible. If not accessible it refers you back to (B) (B) allows the breaker to be the disconnecting means if the breaker is within sight from the appliance or has a permanent means of locking the breaker open that remains in place regardless of whether the lock is in use or not. Article 100 defines “within sight from” as being within 50 feet of the appliance. This is located 65 feet away so it is not within sight from. The breaker can be locked out but only temporarily. This installation would require a separate disconnecting means.
