Cable Repair Instructions
(Twin Element Cable)
Installation
- Remove the damaged section of heating cable then strip 38mm of the outer insulation from both sides of the cut heating wire ends.
- Separate the two inner heating conductors and metal earth screen then remove 8mm of the heater conductor insulation.
- Slide the large heat shrink onto one side of the heating cable / mat. Once repair is complete, this tube will seal the complete repair.
- Remove 8mm of insulation from both sides of the 100 jumper cables.
- Cut the earth jumper cable to size.
- Slide on the small heat shrink sections onto the conductor jumper cables to create a seal once crimped.
- Using a crimp tool and the smaller crimps, carefully connect the heating cables to the jumper wires.
- Larger crimps for connecting earth cable.
- Centre the small heat-shrink tubes over the connectors and using a heat gun shrink into place.
- Using a crimp tool, connect the earth jumper cable to the metal earth screen sections using the larger crimps
- Centre the large heat shrink tube over the whole splice section and using a heat gun, shrink into place
Testing
The heat mat / cable MUST then be tested. The heating cable resistance should be compared to the value within the instruction manual or on our website. Also test to Live & Earth and Neutral & Earth to make sure no cables are touching.
Electrical Considerations
As with all electrical projects governed by Part P regulations, all mains
electrical connections must be undertaken by a certified electrician.
Please Note
If the two pieces of heating cable can be pulled together the jointing
piece is not required, providing no heating cable is lost from its length.
