Each 20 amp/277 volt circuit shall be comprised of flat copper busbars and have a separate neutral busbar for each circuit busbar. The neutral busbar shall be oversized to be comparable to #10 gauge 30 amp wire to reduce the possibility of overheating due to non-linear loads and harmonics.; Track shall have integral wiring channels for six (6) additional #12 THHN wires to create three (3) additional 20 amp/277 volt circuits, which can be dropped into any Joiner/Feeder, for a total track power capacity of 100 amps.; LSI Surface Track has the ability to be mounted directly to any horizontal/vertical surface or suspended from a surface by field cuttable stainless steel cables or steel stems.
