Product FAQs
7 answersWhat panelboards are compatible with the Square D EDB24070?
The EDB24070 is an E-frame bolt-on circuit breaker designed specifically for use in Square D NF series panelboards. It cannot be installed in NQ, I-Line, or standard QO load centers.
What is the difference between Square D EDB, EGB, and EJB circuit breakers?
The primary difference is their maximum interrupting capacity at 480Y/277VAC. The EDB series is rated for 18kAIC, the EGB series for 35kAIC, and the EJB series for 65kAIC. All three share the same physical footprint and mount in NF panelboards.
What are the lug torque specifications for the EDB24070?
The required tightening torque depends on the wire size used. Torque the lugs to 34.5 lbf-in for 14 to 10 AWG conductors, and 49.6 lbf-in for 8 to 2/0 AWG conductors.
Can the EDB24070 be used on a 120/240V or 240V system?
Yes. While it has a maximum voltage rating of 480Y/277VAC, it is fully rated for use on 120/240VAC and 240VAC systems. When used at these lower voltages, the interrupting rating increases to 25kAIC.
Does the EDB24070 provide equipment ground fault protection (EPD)?
No, the standard EDB24070 features standard thermal-magnetic trip units for overload and short-circuit protection only. Square D E-frame breakers with 30mA equipment ground fault protection will include an EPD suffix in the catalog number.
How much panel space does the EDB24070 require in an NF panelboard?
As a 2-pole E-frame breaker, the EDB24070 occupies two standard pole spaces in a Square D NF circuit breaker panelboard.
Is the Square D EDB24070 HACR rated?
Yes, this breaker is HACR rated, meaning it is approved for use with heating, air conditioning, and refrigeration equipment group motor loads.

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.
