Product FAQs
8 answersWhat panelboards are compatible with the Square D EGB24110?
The EGB24110 is an E-Frame bolt-on circuit breaker designed exclusively for use in Square D NF series panelboards.
What is the difference between Square D EDB, EGB, and EJB circuit breakers?
The difference lies in their interrupting capacity (AIC rating) at 480Y/277VAC. EDB breakers are rated at 18kAIC, EGB breakers (like the EGB24110) are rated at 35kAIC, and EJB breakers are rated at 65kAIC. All three share the same physical E-Frame footprint and mount in NF panelboards.
How many spaces does the EGB24110 occupy in an NF panelboard?
As a 2-pole circuit breaker, the EGB24110 requires two mounting spaces in a Square D NF panelboard.
Is the EGB24110 circuit breaker HACR rated?
Yes, Square D E-Frame breakers in this amperage range are HACR rated, making them suitable for use with heating, air conditioning, and refrigeration equipment.
What is the recommended tightening torque for the EGB24110 terminals?
The factory aluminum lugs require a tightening torque of 3.9 N.m (approximately 35 lb-in) for 14 to 10 AWG wire, and 5.6 N.m (approximately 50 lb-in) for 8 to 2/0 AWG wire. Always verify exact torque specifications on the breaker faceplate before installation.
Does the EGB24110 feature a tripped circuit indicator?
Yes, this breaker includes the Square D Visi-Trip feature. When the breaker trips due to an overcurrent or short circuit, a highly visible red indicator appears to help quickly identify the faulted circuit.
Can I use copper or aluminum wire with the EGB24110?
Yes, the EGB24110 comes standard with factory-installed aluminum lugs that are dual-rated for both copper (14 to 2/0 AWG) and aluminum (12 to 2/0 AWG) conductors.
What does the LI trip function mean on the EGB24110?
LI indicates that the thermal-magnetic trip unit provides Long-Time (L) protection for standard overloads and Instantaneous (I) protection for short circuits. Both settings are fixed on this E-Frame breaker.
