Product FAQs
6 answersWhat panels are compatible with the QO230EPD2100 circuit breaker?
This plug-on breaker is designed exclusively for Square D QO load centers and NQ panelboards. It cannot be installed in Homeline panels or load centers from other manufacturers.
What does the EPD designation mean on this Square D breaker?
EPD stands for Equipment Protection Device. It provides a 30mA ground fault trip threshold (Class B) designed to protect machinery and equipment from damage, rather than the 5mA threshold used in Class A GFCI breakers for personnel protection.
What feature does the 2100 suffix indicate on the QO230EPD2100?
The 2100 suffix signifies that the breaker includes a factory-installed alarm switch, also known as a bell alarm. This switch provides remote signaling to a monitoring system when the breaker trips due to an overload, short circuit, or ground fault.
How is the neutral connection handled on the QO230EPD2100?
This breaker utilizes a pigtail neutral connection. The attached coiled white wire must be routed and secured directly to the neutral bus bar in the panel for the ground fault equipment protection to function correctly.
How can I visually identify if the QO230EPD2100 has tripped?
This breaker features the Square D Visi-Trip indicator. When a fault occurs, the handle snaps to a center position and a bright red flag appears in the indicator window, making it easy to locate the tripped circuit in a crowded panel.
Can I use the QO230EPD2100 in place of a standard GFCI breaker?
No. This is a 30mA Equipment Protection Device and does not provide the 5mA Class A personnel protection required by the National Electrical Code for standard GFCI applications like bathrooms or kitchens. For 5mA personnel protection, a QO230GFI is required.
