- UL approved for use in direct burial applications including concrete and earth burial (Sizes 3/8“ through 4”)
- Conduit in sizes 11⁄2″ and larger requires grounding conductor per NEC® 350.60
Grounding
Permanent circuit ground protection is provided through the continuous bonding strip built into the conduit core in sizes 3/8“ through 11⁄4”. A separate grounding conductor is required by the NEC® for trade sizes
11⁄2″ and larger. The Canadian Electric Code requires a grounding conductor for all trade sizes of Liquidtight Flexible Metal Computer Blue Conduit.
Markings
The surface of the outer jacket shall be clearly marked with a legible print legend in compliance with UL 360 and CSA C22.2 No. 56.
