NEC 2020 Proposals-Public Comment thru August 30

[STEVETERRY]

Proposed changes to the National Electrical Code 2020 edition are now open for public comment through August 30, 2018 here:
https://www.nfpa.org/codes-and-stan...-and-standards/detail?code=70&tab=nextedition

Proposed changes to the entertainment articles of the Code are largely editorial. One interesting exception is proposed 520.68(A)(2), which would allow Hard Usage cable (type SJ and derivatives) in theatres in "protected applications" up to 100' in length. Currently, Extra-Hard Usage cable (type S and derivatives) is required in all theatre applications except breakout assembles, stand lamp cords, twofers and adapters, and luminaire supply cords. This proposal represents a significant expansion of allowed type SJ uses.

Going through this, which is the quickest way to see just the 520 changes? Going through 3295 pages is not easy.

Are you looking at the First Draft Report? There should be a hot linked table of contents on the left of the screen. You can go right to article 520.

So what does protected applications mean? I'm assuming its, supported on a pipe or in a set unit and such. And maybe avoid the floor, as per usual.

Thanks Steve for your work on this.

Thanks Steve for your work on this.

Here is what is proposed as an addition to 520.68 and has passed the first round of voting in Code Panel 15:

2) Protected Applications.
Listed, hard usage (junior hard service) cord or cable shall be permitted where all of the following conditions are met:

1. The cord or cable is protected from physical damage by attachment over its entire length to a pipe, tower, truss, scaffold, or other substantial support structure, or installed in a location that inherently prevents physical damage to the cord.
2. The cord or cable is connected to a branch circuit protected by an overcurrent protective device rated at not over 20 amperes.
3. The cord or cable does not exceed 30 m (100 ft) in length.

You can make a public comment on this up until August 30, 2018 at 5PM EDT if you think it needs changing. See nfpa.org/70
