Product FAQs
6 answersWhich electrical panels are compatible with the QBH1020CAF breaker?
This bolt-on breaker is designed for use in legacy Commander B and BC series load centers, as well as CEB and Sylvania bolt-on panels. It features a 3/4-inch per pole form factor specific to these classic panel designs.
What type of arc fault protection does the QBH1020CAF provide?
This is a Combination Arc Fault Circuit Interrupter (CAFCI). It protects against both parallel arcs (between hot and neutral or ground) and series arcs (along a single broken or damaged conductor), providing comprehensive fire prevention for residential branch circuits.
How is the neutral wire connected when installing this AFCI breaker?
The QBH1020CAF features a pigtail neutral connection. The coiled white pigtail wire must be connected directly to the panel neutral bus bar, and the circuit load neutral wire connects to the designated neutral terminal on the breaker itself.
What does the 22kAIC interrupting rating mean for this specific breaker?
The 22kAIC rating indicates the maximum fault current the breaker can safely interrupt without sustaining damage. At 22,000 amps, it offers a higher fault current tolerance than standard 10kAIC breakers, making it suitable for systems located closer to the utility transformer.
Can I use the QBH1020CAF to replace older standard Commander QBH breakers?
Yes, this breaker is a direct replacement for standard 20A Commander, CEB, or Sylvania QBH breakers when upgrading a circuit to meet modern combination arc fault code requirements.
What does the LI trip function indicate on the QBH1020CAF?
The LI designation means the breaker includes both Long-Time and Instantaneous trip functions. The Long-Time function provides thermal protection against sustained overloads, while the Instantaneous magnetic function trips immediately in the event of a severe short circuit.
