Frequently Asked Questions

What is the purpose of a dual-function circuit breaker?

A dual-function circuit breaker provides both GFCI (Ground Fault Circuit Interrupter) and AFCI (Arc Fault Circuit Interrupter) protection. It helps to detect and prevent electrical hazards such as ground faults and arc faults.

How does the SIEMENS Q120DFN compare to other circuit breakers?

The SIEMENS Q120DFN stands out for its dual-function capability, combining GFCI and AFCI protection. It is also known for its easy installation process and affordable price.

What is the main advantage of plug-on neutral load centers?

Plug-on neutral load centers simplify and speed up the wiring process by allowing the branch neutral conductor to be returned directly to the neutral terminal bar, eliminating the need for separate pigtails.

Can the SIEMENS Q120DFN be used for residential applications?

Yes, the SIEMENS Q120DFN is specifically designed for residential applications and provides enhanced electrical safety for homeowners.

What is the difference between GFCI and AFCI protection?

GFCI (Ground Fault Circuit Interrupter) protection detects imbalances in electrical currents, such as when current flows through a person instead of the intended circuit. AFCI (Arc Fault Circuit Interrupter) protection detects potentially dangerous arc faults, which are often caused by faulty or damaged wiring.
