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 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.
