Description
Part of the BR family, the Eaton GFTCB230 provides 30A of ground-fault protection for 120/240VAC circuits. It is specifically engineered to meet NEC requirements for areas prone to moisture, such as bathrooms, kitchens, and outdoor receptacles. Featuring a standard plug-on design, this breaker fits seamlessly into Eaton BR, Bryant, Challenger, and Westinghouse load centers. It replaces the older GFCB230 and has since been replaced by the BRN230GF in Eaton's current catalog.Specifications

Product FAQs
7 answersWhich electrical panels are compatible with the GFTCB230?
This plug-on breaker is designed for use in Eaton BR load centers. It is also backward compatible with legacy Westinghouse, Challenger, and Bryant load centers that accept Type BR breakers.
What level of ground fault protection does the GFTCB230 provide?
It provides Class A ground fault protection with a 5mA trip sensitivity. This level of protection is designed for personnel safety in wet or damp locations, such as outdoor circuits, spas, and bathrooms.
How is the neutral connection wired on this breaker?
The GFTCB230 features a pigtail neutral connection. The coiled white pigtail wire must be connected directly to the panel's neutral bus bar to ensure the ground fault circuitry functions correctly.
What wire sizes are accepted by the GFTCB230 terminals?
The box lugs on this breaker accept copper or aluminum conductors ranging from 14 AWG to 4 AWG.
What is the recommended terminal tightening torque for this breaker?
The load terminals on the GFTCB230 should be tightened to 20 lb-in. Always use a calibrated torque tool to ensure a secure connection and prevent thermal issues.
Can this breaker replace older Bryant or Westinghouse GFCI breakers?
Yes, the Eaton BR series is the direct, UL-listed replacement for older Bryant, Westinghouse, and Challenger Type BR breakers of the same amperage and pole configuration.
Is this breaker suitable for 240V hot tub or spa applications?
Yes, as a 2-pole, 30A breaker with 5mA GFCI sensitivity, it is commonly used for dedicated 240V circuits requiring personnel protection, such as hot tubs and spas, provided the 30A rating matches the equipment requirements.
