SKU CH-S1B7-DQ6XK

Self-regulating heating cable runs 250 ft at 120 VAC, delivering 6 W per foot at 40 °F with a 200 ft maximum circuit length

  • TypeTarps
  • Self-regulating output prevents overheating at 150 °F max
  • 250 ft length covers long pipe runs in one piece
  • Hardwired 120 V AC connection suits permanent installs
  • Tinned-copper braid adds mechanical protection and ground path

Electric Heating Cable 250 ft

This self-regulating electric heating cable comes in a 250 ft length for indoor hardwired installations. It operates on 120V AC at 50 Hz and delivers 6 watts per foot at 40 degrees F. The cable uses conductive carbon core with tinned-coated copper covering.

Suits pipe freeze protection and roof de-icing

Homeowners protecting water pipes from freezing or preventing ice dams on roofs will find the 250 ft length practical. Buyers needing longer continuous runs beyond the 200 ft max circuit length should look at alternative configurations. Outdoor installations are not supported by this indoor-only cable.

Max circuit length 200 ft

The 200 ft maximum circuit length is the critical specification for planning any installation. Circuits longer than this limit require separate power feeds to operate safely. This constraint directly determines how the 250 ft roll must be divided across your project.

Questions about this item

What voltage supply must already be available for the Raychem 735039-000 cable to operate?

The cable requires a 120 V AC supply at 50 Hz, so the installation site must provide that voltage and frequency before the cable can be connected.

Can the 250 ft roll be run as a single circuit alongside an existing 200 ft maximum-circuit-length system?

The maximum circuit length is 200 ft, so a single 250 ft run exceeds that limit; the roll must be split into two or more circuits each no longer than 200 ft to work with existing wiring.

How can I verify the cable is heating correctly after it is hardwired and energised?

At 40 °F ambient the cable draws 0.05 A per foot and delivers 6 W per foot; measuring current per foot or feeling gradual warmth along the length confirms normal self-regulating operation.
