Rated 65 kAIC at 120V, this 30A equipment protection device (EPD) delivers reliable thermal-magnetic trip functions. It safeguards commercial machinery against damaging ground faults with a 30mA trip threshold. The E-Frame bolt-on breaker mounts securely into Square D NF panelboards. It features a 1-pole configuration and accepts 14-6 AWG copper wiring. Beyond standard overcurrent defense, the EGB14030EPD includes a Visi-Trip indicator and is HACR and HID rated for specialized applications.

Product FAQs
8 answers
What does the EPD suffix indicate on the EGB14030EPD?
The EPD suffix designates this as an Equipment Protection Device. It provides ground fault protection with a 30mA trip level, designed to protect equipment rather than personnel.
What is the difference between EPD and GFI breakers?
EPD (Equipment Protection Device) breakers trip at a 30mA ground fault threshold to prevent equipment damage, commonly used for heat tracing or snow melting equipment. GFI (Ground Fault Circuit Interrupter) breakers trip at a 5mA threshold to provide Class A personnel protection.
Which panelboards are compatible with the EGB14030EPD?
This E-frame bolt-on circuit breaker is designed exclusively for use in Square D NF series panelboards. It will not fit in NQ or I-Line panelboards.
How is the ground fault circuit completed during installation?
The EGB14030EPD includes a factory-installed pigtail neutral wire. This pigtail must be connected directly to the panelboard neutral bar to power the internal ground fault circuitry and ensure proper operation.
Can I use shared neutrals with this EPD breaker?
No. Ground fault equipment protection breakers require a dedicated neutral for the specific circuit they protect. Using a shared neutral will cause an imbalance in the current transformer and result in nuisance tripping.
What is the difference between EDB, EGB, and EJB frames?
The second letter in the prefix indicates the interrupting rating. EDB is standard (18kA at 277V), EGB is high interrupting (35kA at 277V), and EJB is extra-high interrupting (65kA at 277V). The EGB14030EPD is the high interrupting variant.
Can this bolt-on breaker replace a plug-on type?
No. The EGB14030EPD features a bolt-on connection specific to NF panelboards. It cannot be used to replace plug-on breakers or be installed in load centers designed for plug-on connections.
How often should the ground fault protection be tested?
Square D recommends testing the ground fault function monthly using the integrated test button on the breaker face to ensure the internal circuitry is functioning correctly.
