What is Changing?

The anticipated 2017 NEC includes several sections with new short-circuit protection requirements. The most significant changes will require that the available fault current at the location where the equipment is installed is marked/documented and dates.

Marking Requirements

The available short-circuit current must be marked on the following equipment types: Machinery, HVAC Equipment, Elevator Control Equipment, Generator Equipment, Transfer Equipment, Energy Storage Equipment, and Battery Systems Equipment.

Documentation Requirements

The available short-circuit current must be documented on the following equipment types: Motor Control Centers and Equipment with Industrial Control Panels.
