Right here.
I need to sleeve a piece of 2-2-2-4 SER cable in EMT where it will run exposed in a hallway. From the link in the previous sentence, I get the diameter of this cable to be .955", so that would would make the cross-sectional area .716". If I'm allowed 53% fill for a single cable being sleeved, it seems like I need a pipe with at least 1.350" of cross sectional area. Looks like 1-1/4" EMT, with its 1.496" cross sectional area would do the trick.
 
I also did a cross ref. of your SE dia. It's just a tad larger than one 500 kcmil.
did I say "Tad"? There's no "Tad" in engineering!! :grin:

It will work as long you are sleeving in short section but however if you going to use other type of conduits you have to bump up to 1.5 inch size but for the type of cable you have there 1.25" EMT work fine [ i ran my numbers in metric and reinverted back to standrd numbers and it match it what you are asking for ]

Merci,Marc

[ for moi,.. i will just run with 1.5 inch stick and be done with it sometime some of the SER cable have a kink or oddball hump it can ruin your day ]
