Product FAQs
7 answersWhat panelboards are compatible with the Square D EGB24070 circuit breaker?
The EGB24070 is designed exclusively for use in Square D NF series panelboards. It is a bolt-on E-frame breaker and is not compatible with NQ, QO, or I-Line panelboards.
What is the difference between the EDB24070, EGB24070, and EJB24070 breakers?
These breakers share the same physical E-frame footprint and NF panelboard compatibility, but they have different interrupting ratings at 480Y/277VAC. The EDB24070 is rated at 18kAIC, the EGB24070 at 35kAIC, and the EJB24070 at 65kAIC.
What does the 35kAIC rating mean for the EGB24070?
The 35kAIC rating indicates the maximum fault current the breaker can safely clear at 480Y/277VAC. The G interrupting tier represents the mid-level short-circuit rating for Square D E-frame breakers.
What are the wire size and torque requirements for the EGB24070 lugs?
The factory lugs accept 14-2/0 AWG copper or 12-2/0 AWG aluminum wire. The recommended tightening torque is 35 lb-in for 14-10 AWG wire and 50 lb-in for 8-2/0 AWG wire.
Are the trip settings adjustable on the EGB24070?
No, the EGB24070 features a fixed thermal and fixed magnetic trip unit. The long-time and instantaneous trip functions cannot be adjusted in the field.
Can the EGB24070 be reverse fed?
Yes, standard thermal-magnetic E-frame breakers like the EGB24070 are not marked with line and load designations, making them suitable for reverse feeding in back-fed main applications.
Does the EGB24070 provide equipment ground fault protection?
No, the standard EGB24070 features a standard thermal-magnetic trip unit for overload and short-circuit protection. Breakers requiring 30mA equipment ground fault protection require an EPD catalog suffix.
