If you had to temp out indoor120/208v panels with the following size feeds what would you use. 4#2's w/1#8 & 4 #4/0 w/#4?

I ask because romex is always preferred but in this case because of the size feeders and romex is not available in size or configuration I'm thinking MC cable is best/cheapest option.
 
MC cable is fine and is what we use. I've also seen guys use SER cable but that could easily be subject to damage on a construction site. If you need a similar replacement for NM cable then go with SE cable.
 
Here's the situation and maybe someone can tell me if my thinking is correct and fill in what I maybe missing?

Three new panels right next to each other that have to be temped, not simultaneously. due to time frame. There are three other panels being demolished. Their ckts and main feeder will be swing over to the new panels. When one panel is temped out and the extg.loads(branch circuits) are swung over then the permanent main feeder(that was feeding the demoed panel) is intercepted and brought over to the new panel the same will happen with the other two.


The new panels feeders are as follows. (2) panels are 100A and are feed with 4#2 and #8 and the other is 4#4/0 and #4.

I think this is obviously. I see no reason to run three separate temp feeds. if I temp put the 225A panel first can't I use that feeder, when I'm done with the permanent for that panel, to temp feed the smaller panels even though it'll be a 4/0 feeder? I can tap and downsize the conductors. no?

Thanks,

Nobody in this area is using MC for typical temps. SER is used all the time on construction site temps.

How about if you in a functioning/operational building and you need to temp out a panel? Not your typical renovation or new construction?

Same as Bob/iwire posted already. I have used SER for temp panels in fully staffed and enrolled academic buildings.

Thanks.
I know SER is takes more labor per M than MC of the same size....just looking at Means and NECA labor units. Guess it's heavier. Maybe the material cost offsets the labor cost.

I fail to see why SE would take more labor (at least any significant differences) to install then MC of the same size and number of conductors. Termination may have different cost but that is the same whether you have 10 feet or 1000 feet of run.

Well I just checked the weights per M/lbs on Southwire and they are both about the same for a given size. Not sure why NECA would have the labor units so drastically different.
