Designed to support legacy infrastructure, the Square D EHB14020 is a 1-pole, 20A molded case circuit breaker. It delivers reliable overcurrent protection for commercial and industrial facilities, complete with a Visi-Trip indicator to easily spot tripped circuits. This breaker mounts into obsolete Square D NEHB panelboards via a bolt-on connection. If upgrading your system, an NF panelboard with EDB series breakers is required. It features a 14kAIC rating at 277VAC and is HACR and SWD rated.
What panelboards are compatible with the EHB14020?
The EHB14020 is designed exclusively for use in legacy Square D NEHB panelboards [1.2.7]. It features a bolt-on connection that fits the specific NEHB bus design.
Can I use a modern EDB breaker to replace the EHB14020?
No. EHB and EDB breakers are not interchangeable. EHB breakers fit older NEHB panelboards, while modern EDB series breakers are built for current Square D NF panelboards.
Is the Square D EHB14020 still in active production?
No, the EHB series and the corresponding NEHB panelboards are considered legacy equipment and have been obsolete since the 1990s. The EHB14020 serves as a direct replacement part to maintain existing NEHB infrastructure without requiring a complete panelboard swap.
What wire size is required for installing the EHB14020?
The integrated lugs on the EHB14020 accept 14 to 10 AWG copper conductors or 12 to 10 AWG aluminum conductors.
What are the specific interrupting ratings for the EHB14020?
The EHB14020 provides a 65kAIC rating at 120VAC and a 14kAIC rating at 277VAC. This makes it highly suitable for commercial 277V lighting and single-phase branch circuits that require a 14kA short circuit current rating.
How can I visually identify if the EHB14020 has tripped?
The EHB14020 is equipped with the Square D Visi-Trip indicator. When the breaker trips due to a fault or overload, a highly visible indicator appears, helping maintenance personnel quickly locate the tripped circuit inside a crowded panel.

Fast reliable service, reasonable prices
I recently ordered the incorrect breakers for a job, but I contacted Drew at SuperBreakers and he got me the correct breakers shipped out that day, which I received the next day. He sent me a label to send the wrong breakers back, and I was quickly refunded a restocking fee that I incurred for my mistake. I was able to get the breakers installed, and the power running to meet the deadline. Not to mention, the price was better than I found elsewhere. Thanks Drew!
I would definitely recommend this company if you need fast, reliable service for your electrical product needs. And I'm sure I will use them again.
Thank you SuperBreakers! Nice job Drew!
