Illustrated Changes to the NEC, 2005 Edition - Part 2

Article 702

Optional Standby Systems

702.11 Outdoor Generator Sets

Part IV. Sources of Power

New section added to coordinate the disconnecting means requirements between emergency, legally required, and optional standby power systems.

Where an outdoor-housed generator is equipped with a readily accessible disconnecting means located within sight (within 50 ft) of the building or structure, an additional disconnecting means isn't required on or at the building or structure for the generator feeder conductors that serve or pass through the building or structure.

Author's Comment: Similar requirements are contained in 700.12(B)(6) for emergency power systems and 701.11(B)(5) for legally required standby systems.
