Product FAQs

7 answers
What is the ground fault trip level for the THQB1115GFEP?

This breaker provides Ground Fault Equipment Protection (GFEP) with a 30mA trip threshold. It is designed to protect machinery and equipment from damage, rather than providing the 5mA personnel protection found in standard GFCI breakers.

Which panelboards are compatible with the THQB1115GFEP circuit breaker?

This bolt-on breaker is designed for use in GE A-Series panelboards, GE AQ lighting panels, and compatible ABB ReliaGear panelboards.

What wire sizes are accepted by the box lugs on this 15A breaker?

The terminal lugs accept 14 to 8 AWG copper wire or 12 to 8 AWG aluminum wire.

How does the THQB1115GFEP mount into the panel?

It features a bolt-on mounting design, which secures directly to the panelboard bus for a reliable connection in commercial and industrial applications.

Why might my THQB1115GFEP breaker arrive with ABB branding instead of GE?

ABB acquired GE Industrial Solutions. Depending on the manufacturing date, this exact breaker may feature either ABB or General Electric branding, but the form, fit, and function remain identical.

Does this breaker require a pigtail neutral connection?

Yes, this breaker includes a pigtail neutral wire that must be connected to the panel neutral bar to ensure the ground fault equipment protection functions correctly.

How does this breaker indicate a tripped condition?

The THQB series features a quick-make, quick-break mechanism with an easy-to-spot trip indication, allowing you to quickly identify when the breaker has tripped due to an overload, short circuit, or ground fault.

    Hard to find older style breakers

    I am pleased to have access to these breakers. We have a number of them at our church. Local suppliers said that they had never seen this kind of breaker. They fit our panel perfectly.
