Product FAQs
6 answersWhat panelboards accept the EDB34015 breaker?
The EDB34015 is a bolt-on E-frame breaker designed specifically for Square D NF series panelboards [1.2.3]. It will not fit into QO, Homeline, or I-Line panelboards.
Are there higher interrupting rating alternatives to the EDB34015?
Yes. The EDB34015 has a standard interrupting rating of 18kAIC at 480Y/277VAC. If your electrical system requires a higher fault current rating, you can substitute the EGB34015 (rated for 35kAIC) or the EJB34015 (rated for 65kAIC), which are direct drop-in replacements for the same panel space.
What do the LI trip functions indicate on this breaker?
The LI designation means this thermal-magnetic breaker includes fixed Long-Time (thermal overload) and fixed Instantaneous (magnetic short-circuit) trip functions. This is the standard configuration for protecting general-purpose commercial branch circuits.
How does the Visi-Trip indicator work on this breaker?
When the breaker trips due to an overcurrent or short-circuit event, the handle snaps to a center position and a bright red visual indicator appears. This allows electricians or facility managers to quickly identify the faulted circuit in a crowded panel.
What type of wire is required for the EDB34015 terminals?
The factory-installed lugs accept both copper and aluminum wire. You can use 14 AWG to 6 AWG copper conductors, or 12 AWG to 6 AWG aluminum conductors. Ensure the wire insulation is rated for the appropriate temperature of the application.
Can the EDB34015 be used for heating, air conditioning, or high-intensity lighting loads?
Yes, it is HACR rated for use with heating, air conditioning, and refrigeration equipment. It is also HID rated, meaning it is certified to safely handle the temporary inrush currents generated by High-Intensity Discharge lighting circuits.

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.
