Product FAQs

5 answers
What is the recommended terminal torque for the EDB24050?

The tightening torque depends on the installed wire gauge. For 14 to 10 AWG wire, torque the lug to 34.5 lb-in. For 8 to 2/0 AWG wire, apply 49.6 lb-in of torque.

Can I substitute an EGB24050 or EJB24050 for the EDB24050?

Yes. EGB and EJB circuit breakers share the exact physical dimensions and bolt-on footprint as the EDB series. They serve as direct drop-in replacements if your panel requires a higher interrupting capacity, offering 35 kA and 65 kA at 480Y/277VAC respectively.

Is the EDB24050 rated for HVAC equipment and lighting loads?

Yes. The EDB24050 is both HACR rated for use with heating, air conditioning, and refrigeration equipment, and HID rated for high-intensity discharge lighting circuits.

Can the EDB24050 be reverse-fed for backfeed applications?

Yes. Square D E-frame circuit breakers, including the EDB24050, are suitable for reverse-feed applications such as solar backfeeding. Note that while they support AC backfeeding, they are not DC-rated.

Is the 2-pole EDB24050 suitable for corner-grounded delta systems?

Yes. Two-pole EDB, EGB, and EJB circuit breakers are UL Listed for use on 240V corner-grounded delta systems, also known as grounded B phase systems.

    Breaker ordered and delivered.

    Called in as a last attempt because my regular supplier didn't have any of these in stock. I got a very friendly salesperson, and they sold me a new breaker for less than half of what my standard supplier would have. Definitely going here again.
