Product FAQs
8 answersWhat panels accept the Siemens Q220GF?
This breaker is compatible with Siemens load centers and panelboards that accept QP or QPF type branch breakers. You must confirm that your specific panel label lists these types as approved.
What is the ground fault trip threshold for this breaker?
The Q220GF provides Class A ground-fault protection, which means it is designed to trip when it detects a ground-fault leakage current of 5mA.
How do I wire the neutral on the Q220GF?
This breaker features a white pigtail wire that must be connected directly to the panel's neutral bus bar to power the internal GFCI electronics. If your circuit includes a load neutral (for 120/240V applications), it connects to the neutral lug on the breaker itself.
What is the recommended wire torque for the load lugs?
The load terminals on the Q220GF require a tightening torque of 20 lb-in. Always confirm with the specifications printed directly on the breaker to ensure a secure, code-compliant connection.
Is the Q220GF rated for 3-phase applications?
No. This is a 2-pole, single-phase circuit breaker rated for 120/240V AC. It is not designed or rated for use in 3-phase systems.
How many panel spaces does this breaker require?
Because it is a standard 2-pole, 1-inch per pole breaker, it requires two adjacent spaces in the load center, occupying 2 inches of space in total.
Does this breaker feature automatic self-testing?
Yes. Modern Siemens QPF GFCI breakers include a built-in self-test function that periodically checks the internal electronics to ensure the ground-fault protection is actively working.
Can the Q220GF replace older Siemens QF220A breakers?
Yes. The Q220GF is the current catalog number that supersedes older Siemens QF220A and QF220AP models. It provides the same 2-pole, 20-amp, Class A GFCI protection for your load center.
