Just a thought, if people are using utility knives to strip outer jackets, or even using diagional side cutters in a better way to do so, but they didnt' check as pulling off the outer
jacket to see if they nicked conductors, that's bad as a premiss. Metal shell - especially if one I find in the field clamps metal
cord grip onto conductors in say trained persay but not caring - that or the reverse, would not want an easily stripped metal
cord grip about a
stage hand in changing a
plug "so as to adapt."
Years ago I made a "illegal" 5-20P to L21-30P three
phase adaptor for a show using a three
phase AC
distro rack that needed another output and didn't have it. I was proper at least in using the 20A
Edison for the most part - though grumbling about having to make this
adaptor in general given cross
phase concerns. It was necessary. Did my proper work, electrician on site removed all the 5-20 plugs and replaced them given a lot of time to do so. Did a fairly good job of it in replacing commercial grad 5-20 with Eagle grade home owner grade plugs he bought at a hardware store in never realizing that the 20A receptacles in the rack were able to properly do the 5-20
plug. Instead what was after a lot of wated time was 5-15 non-commercial grade plugs - but at least he did properly terminate and
strain relief them. That meant cutting down some on
conductor strip length also as a detail that this idiot but not total one did. So in already doing something that was a bad idea but necessary in over-rule, made it worse just in not attempting to
plug in the 20A
plug installed. Gee that's different, best waste time and money on installing a new
plug. Cannnot imagine how many times I was cursed during this work on changing over a
plug that would have worked fine had they tried or had more knowledge or trust. Believe there was two of them that had to on site be re-wired.
Overall, I do love the Eagle style metal shelled
plug but do prefer the better designes and they insulate better as long as you don't put imporper strip length into the clamp that don't help when
insulation is clamped onto. Eagle style plugs without reading the instructions or experience are certainy easier to use and get bad habits from. Old school Union style pin plugs also reqire some training and even special tools.
Proper training thing, lots of brands of
plug out there and many good or fair enough. Instructions for each brand of
plug very important to master. Many types of
plug, many brands of
plug to also master in reading the instructions on before installing as I would recommend as just a simple step most don't take.
