How to Properly Install THHN Cable During Cold Weather

Cold weather can wreak havoc on your skin, your heating bill and the air pressure in your tires, but did you also know that it can destroy your THHN cable if it’s not handled properly?

THHN cable by nature can become stiff at lower temperatures.  Made of thermoplastic materials like PVC and Nylon, temperatures lower than 14°F can make it susceptible to cracking.

To make sure that your THHN cable doesn’t crack during installation, there are a few simple steps to follow:

  • Store cable indoors when the weather turns cold; a stable temperature of 65°F is best.
  • If this is not possible, bring the cable inside at this temperature for 24 hours before installation
  • Never install THHN cable when the temperature outside is below 14°F
  • While exposed to cold temperatures, do not drop it to the floor and protect the cable from impacts from other objects as this can crack the stiffened material.

After proper installation, THHN cable can safely operate in outside temperatures below 14°F given that it remains stationary.
