Raychem Electric Heating Cable 240VAC 50 ft P000000877

SKU CH-F8QE-WZXVX

Self-regulating heating cable, 50 ft, 240 VAC, 6 W per foot at 40 °F, hardwired, indoor use, max circuit 350 ft

  • TypeTarps
  • Self-regulating heat adjusts output automatically
  • 50 ft length suits residential pipe runs
  • 240 V AC supply matches standard household circuits
  • Operates from -40 °F to 150 °F for year-round protection
  • Hard-wired design eliminates plug-related failure points

240 VAC Self-Regulating Heating Cable

This 50-foot self-regulating heating cable operates on 240 VAC and delivers 6 watts per foot at 40°F. It uses a conductive carbon core with tinned-coated copper braid and is rated for indoor use only. The maximum circuit length is 350 feet and the operating range spans -40°F to 150°F.

Indoor Pipe Freeze Protection Installers

Suited for electricians and maintenance teams protecting indoor metal or plastic pipes from freezing in commercial or residential buildings. The hardwired connection and 240-volt supply match fixed wiring installations. Not for buyers who need an outdoor-rated jacket, a plug-in connection, or a lower supply voltage.

50-Foot Length With 350-Foot Circuit Limit

The cable ships as a single 50-foot length and can be combined on one circuit up to 350 feet total. This maximum circuit length is the key figure for planning how many runs a single breaker can support.

Questions about this item

How is the 50 ft self-regulating cable hardwired and what step is often missed?

Connect the two conductors to a 240V AC branch circuit rated for at least 0.03 A per foot, then fit an approved end seal kit; skipping the seal lets moisture into the conductive carbon core.

What part will need replacement after several seasons of freeze protection duty?

The tinned-coated copper braid and conductive carbon core degrade slowly; plan to replace the entire 50 ft cable once the outer jacket shows cracking or the self-regulating response drops off.

At what length does voltage drop become the limiting factor on a single 240V circuit?

The manufacturer rates the maximum circuit length at 350 ft; beyond that the 6 W per foot output at 40F cannot be maintained and the cable will under-heat.
