What it is

The Worcester Bosch mains cable (without switch on/off), part number 8737712820, is the mains supply lead for Worcester Bosch Greenstar gas boilers. It carries the 230 V supply into the appliance on models where switching is provided elsewhere in the installation. The cable is supplied without an integral on/off switch.

Signs this part needs replacing

  • Cuts, abrasion, crushing or other damage to the outer sheath
  • Exposed, discoloured or frayed conductors at the terminal or plug end
  • Brittle, scorched insulation or a burning smell around the mains connection
  • Intermittent or total loss of power to the boiler with the supply confirmed live at the spur
  • Cable no longer held by its strain relief and free to move at the appliance entry point

Before you order

  • Confirm the boiler model against the fit list above before ordering
  • Check whether the appliance requires the switched or unswitched cable variant
  • Inspect the existing cable and its terminations for damage that may point to a fault elsewhere in the supply
  • Isolate the appliance at the fused spur before removing or refitting the cable
