Roger I was looking at that and MCap HCF could only be used under the subsection of (C)(3)....(3) So one would have to use EMT, IMC or RMC?

That is correct although we do use flexible wiring methods as fixture whips.

Can the emergency branch circuits serving lighting and rec. in a Cat. lab be ran in MCAP HCF or does it have to be installed in EMT.

Sometimes folks use the term "emergency" quite loosley, so I am just asking...are these truly branch circuits fed from an "emergency" system of life safety and critical branch, or just a standby generator feeding some lights and outlets in a lab?

I would say the OP used "Cat. lab" meaning Catheterization Lab which would be patient care meaning these fixtures and receps would be fed from the Critical Branch not the Equipment Branch.

As per Rogers Post yes the OP did say mean to say Cath Lab. I know the OP as I inspect his work often and he is a "sharp one" When he called me we were just confused on the actual writting of 517.30. That is why he "Dave" posted this.
