00:07listed solution for grounding and bonding ladder style cable tray with copper wire.

00:12The bonding conductor should be sized appropriately for the expected fault current in

00:16your tray. Once the conductor has been determined,

00:19select the appropriate clamp for your con size. As listed in the burnie catalog.

00:23Today, we'll be using 250 KC mill which corresponds with the Burnie GC 2929 CT

00:35drill a hole 7/16 of an inch in diameter. After you have selected the appropriate

00:40connector and chosen your mounting location, begin by disassembling the hardware.

00:53Next, apply a generous amount of penetrex A 13 oxide inhibitor compound to the flat portion of

00:59the casting that will be in direct contact with the tray,

01:02press the nur shank bolt into the drilled hole that the clamp will be mounted on.
