However field people seldom determine the conductor fill requirements for a surface metal or nonmetallic raceway article 352 a metal or nonmetallic wireway article 362 or the wire space for a cabinet or cutout box article 373.
Multi conductor splices in wire gutters.
Hey bryan great video and info i originally started off in the 12 volt industry car audio alarm and would use the western union style union splice all the time another great way to do this is to stager the splices on multi conductor wire to prevent any shorting between the splices this will also decrease the overall bulge from all the splices being in one spot.
The nec reference is article 312 8 a splices taps and feed through conductors which allows splicing as long as you do not exceed 75 of the csa of that gutter space and the feed through conductors disconnecting means location are labeled and the conductor total does not exceed 40 fill.
