Select OCPDs.

Definition

Selection is based on identifying the types of OCPD fuses used in system wiring (plug, cartridge, blade, type S/SL) identifying the types of circuit breakers in single- and three-phase systems (single-pole 120V, double-pole 208V/240V, triple-pole 480V) using the NEC to determine the correct type of OCPD for use in existing and new installations in accordance with NEC, instructor’s guidelines, and manufacturer's nameplate data.

Process/Skill Questions

  • What is a double pole OCPD?
  • How are OCPDs selected in reference to wire size?
  • Are different manufacturers' breakers interchangeable in the service entrance panel (SEP)?
  • How do you identify whether a system is a single-phase or a three-phase system?
