Product FAQs

5 answers
Which panelboards are compatible with the EGB14020?

This breaker is designed exclusively for Square D NF series panelboards. It bolts directly to the bus and will not fit into QO, Homeline, NQ, or I-Line panelboards.

Can the EGB14020 be used to directly control lighting circuits?

Yes. This 20-amp breaker is both SWD (Switching Duty) and HID (High-Intensity Discharge) rated, meaning it is certified to be used as a regular switch for fluorescent and HID lighting loads.

What is the difference between Square D EDB, EGB, and EJB circuit breakers?

These catalog prefixes designate the short-circuit interrupting capacity of the E-Frame breaker line. EDB is the standard interrupting tier, EGB is the high interrupting tier, and EJB is the extra-high interrupting tier. All three share the same physical dimensions and fit the exact same NF panelboards.

Is this breaker appropriate for 480V systems?

The EGB14020 is a 1-pole breaker rated for 277 VAC maximum. It is commonly used for 277V branch circuits in a 480Y/277V 3-phase, 4-wire system, but a 1-pole breaker cannot be used across phases for straight 480V loads.

Does this E-Frame breaker snap into place or bolt onto the bus?

It features a bolt-on connection. The breaker secures directly to the busbars of an NF panelboard using a mechanical fastener, which provides a highly secure connection for commercial and industrial environments. It is not a plug-on or DIN rail mounted device.
