Product FAQs
6 answersWhat panelboards are compatible with the Square D EDB24080 circuit breaker?
The EDB24080 is a bolt-on circuit breaker designed specifically for use in Square D NF series panelboards. It is not compatible with NQ or QO panelboards.
What is the recommended wire size and material for the EDB24080 lugs?
The factory lugs on this breaker accept 14 to 2/0 AWG copper (Cu) wire or 12 to 2/0 AWG aluminum (Al) wire.
What are the tightening torque specifications for the EDB24080 terminals?
The required torque depends on the wire gauge. For 14 to 10 AWG wire, tighten the lugs to 34.5 lb-in. For 8 to 2/0 AWG wire, tighten to 49.6 lb-in.
Can I upgrade the EDB24080 if my system requires a higher interrupting rating?
Yes. The EDB, EGB, and EJB series share the same physical footprint for NF panelboards. You can replace the EDB24080 (18kAIC at 480Y/277VAC) with an EGB24080 (35kAIC) or an EJB24080 (65kAIC) if a higher fault current rating is required.
Is the EDB24080 rated for direct current (DC) applications?
Yes, in addition to its alternating current (AC) ratings, this thermal-magnetic breaker is rated for up to 125VDC.
What type of trip unit does the EDB24080 use?
It features a fixed thermal-magnetic trip unit that provides both long-time (L) overload protection and instantaneous (I) short-circuit protection.

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.
