Self-Regulating Heating Cable 250 ft 240V

This self-regulating heating cable extends 250 feet and operates at 240V AC. It delivers 6 watts per foot at 40 degrees Fahrenheit for freeze protection. The conductive carbon core adjusts output automatically with temperature changes. It is supplied as cable only for hardwired installation.

Suits pipe freeze protection and roof de-icing

The 250-foot length fits longer runs up to the maximum 350-foot circuit limit. Indoor-only rating excludes direct burial or outdoor exposure without additional protection. Installers needing a factory-fitted plug or shorter pre-assembled lengths should consider other options.

6 watts per foot at 40 degrees Fahrenheit

This power density determines whether the cable can maintain the required temperature for your specific pipe diameter or roof area. Verify the 350-foot maximum circuit length against your layout before purchase. The 150-degree Fahrenheit maximum operating temperature sets the upper safety limit.

Questions about this item

How do I hardwire the 250 ft self-regulating cable to a 240 V supply and what step is often missed?

Connect the two conductors to a dedicated 240 V AC circuit with a ground-fault breaker; the step often missed is installing an end seal kit on the far end before energising the cable.

What maintenance or replacement will the tinned-coated copper braid and conductive carbon core need over time?

Inspect the braid annually for corrosion or mechanical damage; replace any section where the carbon core shows discolouration or the braid continuity is lost.

At what point does the 350 ft maximum circuit length limit the 250 ft run under sustained 6 W per foot output?

The limit appears first when you try to extend the run beyond 350 ft total; at 250 ft you remain within the rated maximum circuit length.
