All Climate Control systems/components shall be protected against combustion caused by a short circuit, stalled motor or over voltages ranging from 16.0 volts to 19.0 volts. The components shall be defined as "protected against combustion" if they do not exceed their maximum fault temperature ratings.The fault temperature conditions will be specified in the component device transmittals. This includes any components touching or close to a heat source. For a typical system this includes: motor windings, wires, connectors, terminals, switches, blower resistors, relays, sensors, actuators, controllersand Air Handling unit.
