Heating cable insulation and electrical resistance tests
• Perform all six (6) insulation and resistance test steps
5
required during installation:
1. Before breaking the security seal and opening the product.
Note: Once the seal is broken, you are then in charge of the cable integrity throughout the
entire installation process. Be sure to follow instructions and observe all precautionary measures.
2. After the installation of the heating cable.
3. Before embedding the heating cable.
4. After embedding the heating cable.
5. After the final installation of coating (for installations under asphalt and paving only).
6. Before connecting the heating cable system.
• Enter results in the measurement table found in the envelope.
• Affix the measurement table to the electrical panel, once completed.
Insulation test
• Only use a calibrated megohmmeter.
• Measure the insulation resistance at the free end of the cold lead,
between the conductor and the ground wire.
• Enter the value measured in the measurement table.
• The value should be greater than 1,000,000 ohms.
• If the value is inferior to 1,000,000 ohms, postpone the work and
contact Ouellet Canada’s specialists at 1 800 463-7043.
Resistance test
• Only use a calibrated multimeter.
• Measure the resistance at the free end of the cold lead,
between both conductors.
• Enter the value measured in the measurement table.
• Check the integrity of the heating cable by comparing the value
measured with the value specified on the cold lead cable.
• If the value measured is null or very different from the resistance rating
at any stage of the installation, postpone the work and contact
Ouellet Canada’s specialists at 1 800 463-7043.
