FROSTGUARD

FROSTGUARD is a brand of pre-assembled electric heating cables designed for freeze protection of pipes, gutters, and roofs in both indoor and outdoor environments. The product line consists of ready-to-install cable assemblies that combine a heating cable, a cold lead, and a termination or plug, eliminating field assembly of electrical connections. This approach reduces installation time and the potential for wiring errors at the point of use. The cables are available in multiple lengths and two voltage classes: 120V AC and 240V AC. The 120V models are supplied with a 3-prong grounded plug (NEMA 5-15P configuration) and a 6 ft cold lead, making them suitable for connection to standard grounded receptacles. The 240V models are hardwired and also include a 6 ft cold lead; one such model is specified for use with an H915 controller. Cable lengths in the current range span from 6 ft to 100 ft, covering short runs such as individual pipe segments and longer runs for extended gutters or roof edges. The heating cables are intended for de-icing and freeze protection, not for process heating or temperature maintenance of industrial fluids. They are constructed for exposure to weather and are rated for both indoor and outdoor use. 3G Electric supplies the FROSTGUARD line as part of its industrial equipment catalog. The company provides access to multiple SKUs, including the FG1 series with 120V plug-in configurations and the FG2 series with 240V hardwired configurations. 3G Electric supports global logistics, allowing buyers to specify the appropriate cable length and voltage for their site requirements. Technical documentation, including voltage, cable length, and connection type, is available for each SKU to assist with selection. For plant engineers and maintenance managers, the key selection criteria are the total length of pipe, gutter, or roof edge to be protected, the available supply voltage, and whether a plug-in or hardwired connection is preferred. The pre-assembled design means that no additional junction box or cable termination kit is required for the heating cable itself, though a controller may be needed for 240V hardwired models. The cables are not intended for use in hazardous locations or for immersion in liquids. They are suitable for typical commercial and residential freeze protection applications, such as water supply lines, drain lines, gutters, and downspouts. 3G Electric maintains inventory of the FROSTGUARD heating cable range and can provide quotations based on specific SKU and quantity requirements. The product family is part of a broader offering of industrial heating and freeze protection equipment, and 3G Electric can assist with identifying the correct model for a given application based on the published specifications.

About FROSTGUARD

Common Applications

Residential water supply pipes — FG1-6P or FG1-18P for short runs of exposed pipe in unheated spaces
Commercial roof gutters and downspouts — FG1-36P or FG1-75P for preventing ice dams on roof edges
Industrial pipe freeze protection — FG2-6L or 12 ft 240V hardwired cable for longer runs requiring higher voltage
Outdoor drain lines — FG1-24P for keeping condensate or waste lines flowing in cold weather
Gutter and roof edge de-icing — FG1-100P for extended lengths on large roof perimeters
Controlled freeze protection systems — 240V hardwired cable with H915 controller for temperature-activated operation

Frequently asked questions

Common questions about FROSTGUARD from 3G Electric.

What voltages are available in the FROSTGUARD pre-assembled electric heating cable line?

FROSTGUARD heating cables are offered in 120V AC and 240V AC versions. The 120V models, such as the FG1-6P, FG1-18P, FG1-24P, FG1-36P, FG1-75P, and FG1-100P, include a 3-prong grounded plug with NEMA 5-15P configuration and a 6 ft cold lead. The 240V models, including the FG2-6L and a 12 ft hardwired version, are designed for hardwire connection and also include a 6 ft cold lead. The 240V 12 ft model is specified for use with an H915 controller. Selection depends on the available supply voltage and whether a plug-in or hardwired connection is required.

What is the maximum length available for FROSTGUARD heating cables?

The longest standard length in the FROSTGUARD pre-assembled range is 100 ft, available in the FG1-100P model. This model operates at 120V AC and includes a 6 ft cold lead and a 3-prong grounded plug. Other lengths include 6 ft, 12 ft, 18 ft, 24 ft, 36 ft, and 75 ft. For runs exceeding 100 ft, multiple cables may be required, or a different product family may be more appropriate. The total length needed should be based on the actual pipe, gutter, or roof edge dimension, plus allowance for connections and any overlap required for valves or fittings.

Can FROSTGUARD heating cables be used outdoors?

Yes. FROSTGUARD pre-assembled electric heating cables are rated for both indoor and outdoor use. They are intended for freeze protection of pipes, gutters, and roofs, and are constructed to withstand exposure to weather. The 120V models with NEMA 5-15P plugs require a grounded outdoor receptacle with appropriate weather protection. The 240V hardwired models require a suitable junction box or controller enclosure. These cables are not rated for hazardous locations or for immersion in water or other liquids. They should be installed according to the manufacturer's instructions and applicable electrical codes.

What is the difference between the FG1 and FG2 series FROSTGUARD heating cables?

The FG1 series comprises 120V AC pre-assembled heating cables with a 3-prong grounded plug (NEMA 5-15P) and a 6 ft cold lead. The FG2 series comprises 240V AC pre-assembled heating cables with a hardwire connection and a 6 ft cold lead. The FG1 models are available in lengths from 6 ft to 100 ft. The FG2 models include a 6 ft length and a 12 ft length; the 12 ft model is specified for use with an H915 controller. The choice between series depends on the supply voltage available at the installation site and whether a plug-in or hardwired connection is preferred.

Does the FROSTGUARD 240V heating cable require a controller?

The FROSTGUARD 240V hardwired heating cables, such as the 12 ft model, are specified for use with an H915 controller. The controller is not included with the cable and must be ordered separately. The 120V plug-in models do not require a controller for basic operation, but a controller can be used to manage power based on temperature or moisture conditions. For any installation, verify that the controller is compatible with the voltage and current draw of the selected heating cable. 3G Electric can provide details on the H915 controller and its compatibility with FROSTGUARD cables.

What is the cold lead length on FROSTGUARD pre-assembled heating cables?

All FROSTGUARD pre-assembled electric heating cables in the current range include a 6 ft cold lead. The cold lead is the unheated section of cable that connects the heating section to the power source. This length allows the heating cable to be positioned on the pipe, gutter, or roof while the electrical connection is made at a convenient point. For 120V models, the cold lead terminates in a 3-prong grounded plug (NEMA 5-15P). For 240V models, the cold lead is prepared for hardwire connection. The 6 ft cold lead is standard across the FG1 and FG2 series.
