Designed for heavy-duty commercial environments, this 15A two-pole breaker delivers reliable thermal-magnetic trip functions. It is optimized for 480Y/277V networks. Fastening firmly into Square D NF panelboards, this unit guarantees a stable connection. It serves as an exact functional substitute for discontinued EHB24015 breakers. A 65kAIC rating at 240V ensures excellent fault clearing. The built-in Visi-Trip indicator simplifies troubleshooting by highlighting tripped status.
What panelboards are compatible with the Square D EGB24015?
The EGB24015 is designed exclusively for use in Square D NF series panelboards. It will not fit in NQ, I-Line, or QO load centers.
What does the G in the EGB24015 part number indicate?
The G designates the interrupting rating tier within the Square D E-Frame family. EGB breakers provide a 35kAIC rating at 480Y/277VAC, which is higher than the standard EDB (18kAIC) but lower than the high-interrupting EJB (65kAIC).
Can I replace an EDB24015 with an EGB24015?
Yes. The EGB24015 shares the exact same physical dimensions and mounting footprint as the EDB24015, but offers a higher short-circuit interrupting rating (35kAIC versus 18kAIC at 480Y/277VAC).
What is the recommended lug tightening torque for the EGB24015?
The load lugs on the EGB24015 should be torqued to 30 lbf-in (3.4 N-m) when using 14 to 6 AWG copper or 12 to 6 AWG aluminum wire.
Can the EGB24015 be used on a 120/240VAC system?
Yes. While it is rated for up to 480Y/277VAC, it is fully compatible with 120/240VAC and 240VAC systems, where it provides an increased interrupting rating of 65kAIC.
Does the EGB24015 require a separate mounting kit?
No. As a bolt-on breaker, the EGB24015 mounts directly to the bus of a Square D NF panelboard using the integrated mounting screws. No additional hardware kit is required.
Is the EGB24015 suitable for reverse-feed applications?
Yes. Standard thermal-magnetic E-Frame breakers like the EGB24015 do not have line and load markings, making them suitable for reverse-feed applications such as backfed main breakers, provided they are properly labeled and secured per NEC requirements.
What type of trip unit is installed in the EGB24015?
It features a fixed thermal-magnetic trip unit providing Long-Time (L) and Instantaneous (I) protection. The thermal and magnetic trip points are factory-set and non-adjustable.
Can I use aluminum wire with the EGB24015?
Yes, the factory-installed lugs are AL/CU rated. They accept 12 to 6 AWG aluminum wire or 14 to 6 AWG copper wire.
