Square D EGB36015 Miniature Circuit Breaker

This bolt-on circuit breaker is designed specifically for use in Square D NF series panelboards.

No, the EGB36015 is an E-frame bolt-on breaker designed exclusively for Square D NF series panelboards. It is not compatible with QO, Homeline, NQ, or I-Line panels.

The factory-installed lugs should be torqued to 30 lb-in (3.4 N.m) for 14 to 6 AWG copper or 12 to 6 AWG aluminum wire.

Yes, this breaker comes standard with factory-installed aluminum lugs that accept both copper and aluminum wire.

Yes. Because it is a bolt-on breaker, it inherently meets the NEC requirement for being mechanically secured to the busbar. However, when used as a back-fed main, a line terminal barrier (such as the NFBFMB20) may be required to comply with local electrical codes.

Yes, this breaker is HACR rated for use with heating, air conditioning, and refrigeration equipment.

These are all 15A, 3-pole E-frame breakers for Square D NF panelboards, but they have different interrupting ratings. The EDB36015 is standard-rated (18kA at 480V), the EGB36015 is high-interrupting (35kA at 480V), and the EJB36015 is extra-high interrupting (65kA at 480V).

The "LI" designation indicates that the breaker's thermal-magnetic trip unit provides Long-Time (L) overload protection and Instantaneous (I) short-circuit protection. Both settings are fixed on this model.

The Visi-Trip indicator provides a clear visual signal when the breaker has tripped due to an overload or short circuit, making it easier to identify the tripped breaker in a crowded NF panelboard.
