Federal Pacific NAGF20 GFCI Miniature Circuit Breaker

No. This breaker features a proprietary plug-on clip design that is strictly compatible with Federal Pacific Stab-Lok load centers. It cannot be installed in standard panels from brands like Square D, Siemens, or Eaton.

Yes. The Connecticut Electric UBIF020N is a newly manufactured, ETL listed replacement that directly crosses over to the original Federal Pacific NAGF20 and NA120GF models.

The coiled white pigtail wire must be connected directly to the neutral bus bar in the panel. The neutral wire from the branch circuit then connects to the designated load neutral terminal on the breaker itself.

The NAGF20 provides Class A ground fault protection. It is calibrated to trip when it detects a current imbalance of 4 to 6 milliamps, which is the standard threshold for personnel shock protection in wet areas.

LIG indicates that the breaker includes Long-Time, Instantaneous, and Ground Fault trip functions. The thermal magnetic components handle standard overloads and short circuits, while the GFCI circuitry monitors for dangerous current leaks to ground.

Manufacturers and the National Electrical Code recommend pressing the test button on the breaker monthly to verify that the ground fault detection circuitry and mechanical trip mechanism are functioning correctly.

Yes. A 10,000 Ampere Interrupting Capacity (10kAIC) is the standard fault current rating for most residential and light commercial branch circuits. Always verify the available fault current at your panel before installation.
