Cable limiters do not have an ampere rating, and cannot be used to provide overload protection. They are instead selected by cable size; for example, a 500 kcmil cable requires a 500 kcmil cable limiter. Their main use is to isolate faulted cables in circuits containing three or more parallel conductors per phase. They may be installed on the line side of the main service to provide shortcircuit protection to the service conductors. This is especially important when service conductors are tapped from large low voltage networks or from large low impedance transformers.

The most common configuration is the offset blade on one end and the crimp terminal on the other end. This permits the limiter to replace a cable terminal (lug). Applications • Service Entrance Conductors • Between Transformer or network bus and bus-way terminal boxes as secondary ties. • Feeders with three or more conductors per phase to share heavier load in large commercial and industrial installations • Multiple Single conductor services, tapped from single (utility) transformer in multi-family residential and small commercial installations. Features • Current-limiting characteristics provide protection to conductor insulation and reduce damage when faults occur. • Properly applied cable limiters may permit the use of equipment with reduced withstand ratings • Wide variety of terminations and cable ratings permit use in almost every situation.
