Frequently Asked Questions:

Q. What is the difference between combination arc-fault and ground-fault circuit breaker?

A. A combination arc-fault circuit breaker detects both series and parallel arcing faults, helping prevent electrical fires caused by loose or damaged wiring, while a ground-fault circuit breaker detects imbalances in current flow between the hot and neutral conductors, providing protection against electrical shocks due to current leakage to ground.

Q. What is the acceptable wire range for the clamp terminal?

A. The clamp terminal can accomodate wire sizes ranging from 14 to 8 AWG of copper or aluminium.

Q. What is the short circuit current rating of this plug-in circuit breaker?

A. It has a short circuit current rating of 10kA.
