GF-1 and GF-2 Ground Fault Protection Units

The National Electrical Code and Canadian Electrical Code both require it. And you know you need it to be compliant.
But a true 30mA trip point GFPE breaker can be hard to find. And, if you DO find one for your specific load center, prepare for special ordering, long lead times, and high costs! If you are working on an older home a GFPE breaker may not be available. And substituting a GFCI may help protect...until the high sensitivity causes a false trip and damage occurs from a non-functioning snow melt system.

The ASE GF-1 and GF-2 provide an inexpensive, easy to integrate answer for your GFPE requirements. Each GF unit affords GFPE protection for one (GF-1) or 2 (GF-2) 120/208/240VAC circuits up to 60A. The unique design allows installation of your own standard, off-the-shelf overload breaker into the customer load center. Size the breaker and wiring for your system, anywhere from 15A to 60A. Then install the GF unit between your load center branch circuit and the sensor/controller and heat cable. Your overload breaker protects the wiring. Our GF unit provides the Ground Fault Protection.

The unit is housed in a rugged, NEMA 4X/IP65 rated enclosure, suitable for mounting indoors or outdoors. The enclosure features a gasket-sealed front access door for easy testing and reset. All internal electronic components are spec'ed for -40oC to +60oC operation. The enclosure is simple to surface mount either near the load center or near the snow melt system, whichever is preferred. Numerous knockout locations on the enclosure provide flexibility for installation and wiring. The enclosure base can accommodate standard 1/2" and 3/4" conduit hubs. Four mounting holes "outside" the enclosure gasket make mounting a breeze while assuring weathertight performance.

The GF-1 and GF-2 can be used directly with our DS series sensors. They can also be used with contactor panels, switches, any system up to 60A. Since the overload protection is provided by the load center breaker only two GF models are required to cover the full range of 15A to 60A, one or two circuits. This keeps stocking costs low but also allows including ground fault protection with kitted systems without the requirement of identifying the customer's load center type and researching if a combined overload/GFPE breaker is available, how long it will take to receive, and at what cost. Odds are a conventional overload circuit breaker is available locally, from stock and at a reasonable price. Including a GF unit in the snow melt kit completes the system and makes it ready to install. And the GF unit provides a ready-made answer when installing or retrofitting a snow melt system in an older facility, one wired well before the term "GFPE" was coined. Its an easy upgrade to help bring an existing system into compliance with modern code requirements.

Important Note: The GF-1 and GF-2 can carry up to 60A but conductor capacity is limited to #14 AWG-#6 AWG wire CU only.
