First, I'm an electrician. I don't install drywall.
I think they typically use drywall screws.

Unless the studs are light weight these ones are popular here and I know for a fact you can zip them into EMT or a 4" sq blank cover easily.

Typically, on commercial jobs I've worked on, only 2x4s are the lighrweight. Heavyweights are usually 2x6 or wider.

Your right, 300.4(A) does not apply to MC cable run through metal framing members.
You just can't run the MC cable parallel to the metal stud at a distance less than 1-1/4 from the nearest edge without protection.

Neither do I but from what I've seen the screws they use will go right a "nailing plate"
Energize the circuit.... when you hear the 'pop', see the sparks, and smell smoke, you know you've got an extra to bill them for. :smile:

Yup, so just install a Colorado Jim or similar strap and you're good to go. No metal plates required.

A Colorado Jim is a Caddy CJ-6 used for MC stacking

I was wondering,"Why do they call a Cable stacker a Colorado Jim?"
Then I saw the Caddy number "CJ-6". LOL Clever.

Isn't Caddy the outfit that, if they produce a design you bring to them, names it after you? Or is that Arlington?
