Description
Engineered for commercial applications, the Square D EDB14050EPD is a 50A equipment protection device (EPD). It delivers thermal-magnetic overcurrent defense alongside integrated 30mA ground fault sensing to prevent machinery damage. This E-frame breaker mounts into Square D NF panelboards. Although it operates as a 1-pole breaker, the integrated electronics module requires it to occupy two pole spaces. Rated 18 kAIC at 277V, it features a Visi-Trip indicator and push-to-test button.Specifications

Product FAQs
9 answersWhat panelboards are compatible with the EDB14050EPD?
This E-frame bolt-on circuit breaker is designed exclusively for use in Square D NF series panelboards. It is not compatible with QO or Homeline load centers.
What does the EPD suffix mean on this Square D breaker?
EPD stands for Equipment Protection Device. It provides ground fault protection with a 30mA trip threshold, designed to protect machinery and equipment rather than providing the 5mA personnel protection found in standard GFCI breakers.
How many panel spaces does the EDB14050EPD require?
Although it operates as a 1-pole breaker, the integrated ground fault electronics module requires it to occupy two pole spaces in the NF panelboard.
How is the neutral connection made for the ground fault feature?
The breaker includes a pigtail neutral wire that must be connected directly to the panelboard neutral bar to power the ground fault sensing circuitry.
What is the difference between Square D EDB, EGB, and EJB breakers?
They share the same physical E-frame footprint for NF panelboards but have different interrupting ratings. At 277VAC, the EDB is rated at 18kAIC, the EGB at 35kAIC, and the EJB at 65kAIC.
What type of wire can be used with the EDB14050EPD terminals?
The factory-installed lugs accept both copper (14 to 6 AWG) and aluminum (12 to 4 AWG) conductors. Ensure the wire is sized appropriately for the 50A rating and torqued to the manufacturer specifications.
Can the 277V EDB14050EPD be used on a 120V circuit?
Yes. While it has a maximum voltage rating of 277VAC with an 18kAIC rating, it is fully rated for use on 120VAC systems, where it provides a higher interrupting rating of 25kAIC.
Does this breaker feature a tripped indicator?
Yes, Square D E-frame breakers include the Visi-Trip visual indicator, which displays a highly visible red flag when the breaker has tripped due to an overcurrent or ground fault condition.
How do I test the ground fault protection on the EDB14050EPD?
The breaker includes a built-in push-to-test button. It is recommended to press this button periodically to verify that the 30mA equipment protection circuitry and mechanical trip functions are operating correctly.
