This for anything physically smaller than 6-2 or 8-3 or 6-3, I assume. Has anybody ever heard a reasonable explanation for the use of "running boards" as opposed to securing the NMC to the bottom of the joists? I can't say I've ever used "running boards ...

2017年6月23日 · In the NEC it requires Romex to be supported on running boards in a crawl space when running the wires perpendicular to the joists on the bottom of the joists..

2023年5月1日 · I have a client that is worried about the Total Harmonic Distortion with his high efficiency furnace. I am currently installing a transfer switch panel for a portable generator. I am looking to get ahead of any issues that may come up with THD. The generator hasn’t been purchased yet, so if there is a generator out there with a …

2015年1月5日 · Wondering if you guys have any methods of mounting panels to block wall. I usually just use toggle bolts but doing some bigger panels/ switch gear that are far to heavy for toggle bolts. Been using drop in anchors but a bit of a pain in the ass to find the solid part of the block to get the anchor to really grab.
