Ok, I have a distro that has a 4 prong 220 at the end of a 25ft cable. This is usually more than enough cable as the hookups are generally right next to the stages we generally play at. This next gig has the hookup almost 100ft from the stage. I have about 150ft of SOOJ 8/3 cable on hand. I know that it is not proper at all to tie ground to neutral ever, and worse comes to worse I will run my 25ft of 8/4 cable as far as I can and use extension cables to the stage from the distro. Is it possible to use the 8/3 cable on the 4 prong outlet with ground to ground, neutral to neutral, and the hot on the 8/3 cable to only one of the hot lugs on the outlet connector? Wouldn't this only feed half of my distro panel? That would be enough for my purposes on this gig. Or is this just BAD? I just don't need to spend $400 on 100ft of SOOJ 8/4 or bigger cable for this one gig. Can I chop up the 8/3 cable to make some heavy duty power cords?

The "right" way to do this (assuming the plug is presently a range plug) is to cut the 25 foot cable about 5 feet from the plug end (or at least long enough to reach the floor from a typical outlet) and install male and female "California style" twistlocks. Now you can go to most any construction rental house and rent a standard 100 foot "spider box" feeder cable which will have the same connectors on either end to extend yours.

Good enough for me. So the 8/3 cable is useless as a feeder cable which is what I expected. So can I just chop it up and make a couple long/heavy duty drop cord?
You'd have to find ends rated to take #8 wire plus the overall diameter of the cable - dunno if there are such animals ?

Any suggestions on places to look at cable ends, twist locks, cables, quad box assemblies ect.... I'm having a heck of a time tring to find a good source. Ideally, I'd like to turn this bunch of cable into 2-3 drop cords with quad boxes on one end.

8/3 is inappropriate cable for any practical use as there are no connectors that will fit that are also suitable for what we do.
L5-30's will fit the cable but then you have to add supplamentary breakers to protect at 20 amps that receptacles (and end product) are listed for.. Not worth the hassle of just doing it right to begin with.
It's legal to drop one phase leg (hot) provided neutral and ground are carried through properly. Not ideal but I can't think of anything unsafe or non-code compliant provided you use proper connectors.

Thanks aged, that was kind of what I was thinking to begin with.....just wanted to ask and I assumed someone in the know would have some specific reason why it was un-good.
So let me get this straight as far as the proper way of doing such a thing. The outlet on the venue end is a 4 prong range plug. I can cut a few feet off the tail that's attached to my distro and put a twist lock connector on the other end of the short piece and one on the end of the tail off the distro......wire these normal with ground to ground, neutral to neutral, x to x, and y to y. On the extension 8/3 cable use a matching twist lock on either end, but wire ground to ground, neutral to neutral, and use only the x or y leg. The one not being used would just dead end in the connectors on either end of the extension cable. How will this functionally change the manner in which my distro functions? Does it matter which hot leg I use if I do use only one? Any good sources for the connectors I need to do this properly?
