Learn the Basics on How to Work With Metal Clad Cable

Save Time With a Whip

Fixture, appliance, and air conditioner whips are short sections of cable or flexible conduit that have not only the wires installed, but the connectors as well. Whips cost a lot more per foot but are a huge time-saver because you don’t need to mess around with cutting the armor. Whips are usually available in 4-ft., 6-ft. and 8-ft. lengths.

Twist and Pull MC Cable

When removing a section of armor to expose the wires, twist the short end of cable counterclockwise as you pull the cable apart. If it feels like it’s taking too much pressure to separate, double-check that the cut went all the way through the armor. Don’t pull too hard or the armor could separate farther down the line. That’s a problem because damaged armor shouldn’t be installed, and you’d have to start over.

Ground the Box

Whether it’s the first box in a line or the only one on an entire circuit, every metal box needs to be grounded. Grounding a box is as simple as connecting the incoming and outgoing ground wires to a pigtail, and then connecting the pigtail to the box with a grounding screw.
