Understanding the Latest Changes to the 2005 National Electrical Code®
ST. LOUIS - Cooper Bussmann makes it easy. Now electrical inspectors, engineers, contractors,
electricians, and plant maintenance personnel have an easy-to-understand, comprehensive
20-page guide to important circuit protection changes to the 2005 National Electrical
The 2005 NEC® has new requirements for certain equipment and motor controllers to
be marked with their short-circuit current rating. It now requires that
industrial panels, industrial machinery electrical panels, certain HVAC equipment, motor
controllers and certain meter disconnects be marked with their short-circuit current rating.
This rating should be equal to or greater than the available short-circuit current where
the equipment is installed in the system.
Selective Coordination is also now required in Articles 700, 701 and 517
for increased system reliability for emergency systems, legally required standby systems,
and essential electrical systems in health care facilities. Selective coordination can
be defined as isolating an overloaded or faulted circuit from the remainder of the electrical
system by having only the nearest upstream overcurrent protective device open.
Other Code changes include series ratings in existing facilities, and application ratings
for motor controllers.
To make sure you are in compliance, ask your Bussmann® representative for a copy of
the Update on 2005 Code Changes or visit www.bussmann.com
