Description
Part of the E-Frame series, the Square D EJB14020EPD delivers 20A, 1-pole commercial power distribution. It functions as an Equipment Protection Device, safeguarding machinery against ground faults with a 30mA trip threshold. The unit installs into Square D NF panelboards via a bolt-on connection, accepting 14-6 AWG copper wiring. Featuring a 100kAIC rating at 120VAC, it ensures robust short-circuit defense. It includes a Visi-Trip indicator and is HACR and HID rated for specialized loads.Specifications

Product FAQs
8 answersWhat does EPD stand for on the EJB14020EPD?
EPD stands for Equipment Protection Device. It provides ground fault equipment protection (GFEP) with a fixed 30mA trip threshold to protect machinery and heat trace systems from damage, rather than the 5mA threshold used for personnel protection.
How many pole spaces does the EJB14020EPD require in a panelboard?
Although it is a 1-pole circuit breaker, the EJB14020EPD occupies two pole spaces in a Square D NF panelboard to accommodate the integrated ground fault protection circuitry.
Which panelboards are compatible with the EJB14020EPD?
This E-frame breaker is designed exclusively for bolt-on installation in Square D NF circuit breaker panelboards. It will not fit QO, NQ, or I-Line panelboards.
What is the difference between EDB, EGB, and EJB EPD breakers?
The difference is their interrupting rating at 277V. EDB breakers are rated 18kA, EGB breakers are rated 35kA, and EJB breakers provide the highest rating at 65kA. They share the same physical footprint and NF panelboard compatibility.
Does the EJB14020EPD require a neutral connection?
Yes, this breaker includes a pigtail neutral wire that must be connected to the panelboard neutral bar. This connection is required for the 30mA ground fault equipment protection circuitry to function properly.
Can I use the EJB14020EPD for personnel protection?
No. This Equipment Protection Device (EPD) has a 30mA trip threshold designed to protect equipment like heat trace systems and pumps. It does not meet the 5mA Class A requirement for personnel protection.
How can I tell if the EJB14020EPD has tripped due to a fault?
The breaker features a Visi-Trip indicator. When the breaker trips due to an overload, short circuit, or ground fault, the handle moves to the center position and a red flag appears in the indicator window for easy visual identification.
Does the EJB14020EPD have a test button?
Yes, it includes a push-to-test button to verify the ground fault protection circuitry is working correctly. Pressing the button simulates a fault and should cause the breaker handle to move to the tripped position.
