Product FAQs
6 answersWhat panelboards are compatible with the Square D EDB24020?
This E-frame bolt-on circuit breaker is designed exclusively for Square D NF series panelboards. It mounts directly to the panel bus and occupies two pole spaces.
Can I upgrade the interrupting rating of the EDB24020?
Yes. If your system requires a higher short-circuit rating at 480Y/277V, you can substitute the EGB24020 (rated 35 kAIC) or the EJB24020 (rated 65 kAIC). Both share the exact same physical dimensions and panel compatibility as the standard EDB frame.
What are the wire gauge and tightening torque specifications for the EDB24020?
The factory-installed aluminum lugs accept 14 to 6 AWG copper wire or 12 to 6 AWG aluminum wire. The standard tightening torque for these terminals is 30 lbf-in (3.4 N.m).
Is the EDB24020 suitable for switching commercial lighting circuits?
Yes, this 20-amp breaker is both SWD (Switching Duty) and HID (High-Intensity Discharge) rated, meaning it is certified for the direct switching of fluorescent and HID lighting loads. It also carries a standard HACR rating for HVAC equipment.
Can the EDB24020 be installed in a straight 480V Delta electrical system?
No. The 480Y/277VAC rating indicates it is strictly for use in solidly grounded Wye systems where the voltage to ground does not exceed 277V. It is not approved for 480V ungrounded or corner-grounded Delta systems.
Does the EDB24020 include a visual trip indicator?
Yes, it features the Square D Visi-Trip mechanism. When the breaker trips due to an overload or short circuit, the handle snaps to a center position and a bright red indicator becomes visible to help electricians quickly locate the faulted circuit.
