Product FAQs
5 answersWhich panelboards accept the Square D EGB24020 circuit breaker?
The EGB24020 is a bolt-on miniature circuit breaker designed exclusively for Square D NF series panelboards.
What are the wire size requirements and lug torque specifications for the EGB24020?
The factory installed lugs accept 14 to 6 AWG copper wire or 12 to 6 AWG aluminum wire. The wire binding screws must be tightened to 30.09 lb-in (3.4 N.m).
How does the EGB24020 differ from the EDB24020 and EJB24020 breakers?
These three E-frame breakers share the same physical dimensions and fit NF panelboards but differ in their short-circuit interrupting ratings at 480Y/277VAC. The EDB24020 is rated for 18kA, the EGB24020 is rated for 35kA, and the EJB24020 provides a 65kA rating.
What does the LI trip function indicate on this breaker?
The LI designation means this thermal magnetic breaker utilizes Long-Time and Instantaneous trip functions. The long-time function provides thermal overload protection, while the instantaneous function delivers magnetic short-circuit protection.
Can a handle padlock attachment be installed on the EGB24020?
Yes, you can install the Square D HPAFD padlock attachment. This accessory secures the toggle, allowing the breaker to be locked in either the ON or OFF position.
