Silas, [I]NEC 520.68(A) Exception 4[/I] -6m maximum link of SJ-derivative cords in the form of breakout. -Must be supported over entire length [I]off the ground[/I] by "pipe, truss, tower, or other substantial support." -Must connect a single multipole connector containing at least two circuits to multiple two pole, 3 wire connectors. -Overcurrent device must not exceed 20A. This essentially describes Socapex breakouts off the ground and tied to the tent or lighting truss. I don't have the handbook readily available, but I [I]think[/I] a Socapex breaking (i.e. 2 pole, 3 wire to single multipole) is also probably legal when connected to a support structure, as it is the reverse of the outlined.
