Product FAQs
7 answersWhat panelboards are compatible with the Square D EDB16015 circuit breaker?
The EDB16015 is an E-Frame breaker designed specifically for use in Square D NF series panelboards. It is a bolt-on breaker that connects directly to the panelboard bus.
Can I install this EDB breaker in a Square D NQ or I-Line panelboard?
No, EDB breakers are exclusively for NF panelboards. NQ panelboards require QO or QOB breakers, and I-Line panelboards require I-Line style plug-on breakers.
What is the difference between Square D EDB, EGB, and EJB circuit breakers?
All three are E-Frame breakers designed for NF panelboards, but they have different interrupting ratings. The EDB is the standard interrupting tier, while the EGB offers high interrupting capacity and the EJB provides extra-high interrupting capacity.
Is the EDB16015 breaker HACR, HID, and SWD rated?
Yes, this 15-amp EDB breaker is HACR rated for heating, air conditioning, and refrigeration equipment. It is also HID (High Intensity Discharge) and SWD (Switching Duty) rated, making it suitable for switching fluorescent and HID lighting loads.
Can the Square D EDB16015 be reverse fed?
Yes, standard EDB thermal-magnetic circuit breakers are suitable for reverse-fed applications. They can be back-fed when used as a main breaker, provided they are installed with the appropriate retaining kit as required by the National Electrical Code.
What does the LI trip function code mean on this breaker?
The LI code indicates that the breaker features fixed Long-Time (L) and Instantaneous (I) trip functions. The long-time function protects against sustained overloads, while the instantaneous function trips immediately during a short circuit.
Does the EDB16015 provide GFCI or AFCI protection?
No, the EDB16015 is a standard thermal-magnetic circuit breaker providing overload and short-circuit protection. It does not include Ground Fault Circuit Interrupter (GFCI) or Arc Fault Circuit Interrupter (AFCI) features.

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.
