Product FAQs

5 answers
What panelboards are compatible with the Square D EH14020 circuit breaker?

The EH14020 is designed exclusively for use in legacy Square D NEHB panelboards. It will not fit in modern NF panelboards or standard residential load centers like QO or Homeline.

What is the difference between Square D EH and EHB circuit breakers?

EH circuit breakers, like the EH14020, utilize a plug-on mounting style. EHB circuit breakers use a bolt-on connection. Square D NEHB panelboards are designed to accept either plug-on EH or bolt-on EHB breakers interchangeably.

Can I use a modern EDB circuit breaker to replace the EH14020 in my NEHB panelboard?

No. While the EDB series is the modern replacement for legacy E-frame breakers, EDB breakers are only compatible with newer NF panelboards. You must use an EH or EHB series breaker to fit an existing NEHB panelboard.

Is the Square D EH14020 rated for switching duty?

Yes, 15A and 20A single-pole EH circuit breakers are UL Listed as SWD (Switching Duty) rated. This makes the EH14020 suitable for switching 120V or 277V fluorescent lighting loads on a regular basis.

Does the EH14020 feature a visual trip indicator?

Yes, Square D EH and EHB series breakers feature a Visi-Trip indicator. This provides clear visual confirmation when the breaker has tripped, simplifying maintenance and troubleshooting in commercial panels.
