Episode 37 – Wiring With MC – WHAT YOU CAN AND CAN’T DO WITH MC CABLE

In this episode we talk in depth about how to wire with MC cable, what the uses permitted and uses NOT permitted are, as well as securing and strapping and a whole host of other tips for use. MC vs ACPhoto courtesy of Paul Abernathy – https://www.masterthenec.comFirst off I suppose it’s good to point out the difference between AC and MC. A lot of people think that it’s the jacketing that separates the two, but actually both come in steel and aluminum jacketing. Really it’s what’s inside that sets the two apart.MC – with full size insulated equipment grounding conductor – photo courtesy of Paul Abernathy – https://www.masterthenec.comAC – with bare #16AWG equipment grounding conductor (bonding conductor) – photo courtesy of Paul Abernathy – https://www.masterthenec.comMC cable typically has either an insulated or bare FULL SIZED equipment grounding conductor inside of it – or sometimes both depending on the purpose of the MC. AC has a small #16AWG equipment grounding conductor in it. The codes in the 2017 NEC have variations in them between MC and AC on things such as bushings as well as the bonding conductor requirements, that is all to say, they are not the same thing. Think Metallica and Megadeth or Audioslave and Soundgarden. Essentially the same…but different. USES PERMITTED AND NOT PERMITTED Want to learn more about becoming an electrician or mastering the craft?
