A buddy is making some changes to his workshop: he is adding a new work bench along a back wall. He wants several 120V outlets along the wall above the workbench for operating various small power tools. He's the only one working there, so he would only be using one tool at a time. The multiple outlets would be for convenience. He is also contemplating a single 240V outlet nearby that he might use to run a larger stationary tool like a table saw; once again, he would not be running any other tools at the same time. Rather then running two separate circuits (120 & 240) from the breaker panel to the back of the shop, he wanted to know if a single circuit can be run from the 240V/20A breaker to the 240V outlet, and then split off two 120V multiwire branch circuits to feed the 120V outlets along the work bench.
