Product FAQs
8 answersWhich load centers are compatible with the LB250-GF?
This breaker is designed exclusively for use in Leviton load centers. It features a plug-on design that connects directly to the panel bus.
Does the LB250-GF require a pigtail wire for the neutral connection?
No. This breaker features a plug-on neutral design. All hot and neutral wires terminate directly at the panel lugs, eliminating the need for a pigtail connection on the breaker itself.
Can the panel be wired before installing this breaker?
Yes. Leviton load centers are designed so that all branch circuit wiring terminates at the panel lugs. This allows the entire panel to be wired during the rough-in phase before plugging in the LB250-GF.
How do I identify the trip condition on this breaker?
The breaker is equipped with intuitive LED indicators on the handle that display the operational status and fault type. Because it uses line-side power, the LEDs remain illuminated even when the breaker is tripped.
What happens if the internal GFCI protection fails?
The breaker features a patented reset lockout mechanism. If the ground fault protection circuitry is compromised, the breaker will not reset, keeping the circuit safely de-energized.
How does ambient temperature affect the trip point of this breaker?
The LB250-GF uses hydraulic-magnetic trip technology, which remains stable across extreme temperatures. It operates precisely from negative 40 to 85 degrees Celsius without requiring any temperature de-rating.
What is the alternate part number for this breaker?
This breaker is commonly listed under the alternate catalog number LB250GF.
What type of faults does the LB250-GF protect against?
It provides standard overload and short-circuit protection, along with Class A ground-fault protection to help prevent electrical shock from leakage current.
