I would bet that is MC cable, we run a lot of MC, we have a job wrapping up now that has 1000's of feet of 250/4 copper MC.
The majority of our prints come with all pipe shown, then the bids go in and the people who have to pay the bill have a heart attack.
They want the building to have all the same features but they want the price reduced.
Changing from EMT to MC drops the labor costs significantly.
Do I think the above installation would look nicer in pipe?
Do I see a safety issue with what is shown?
No I don't.
The support requirements for MC are 6', I do wonder why that one group was not cut shorter so it would not have had to drop down and cross over.
But again there is no telling how much 'value engineering' the customer asked of the contractors.
