    I've always been of the mind that the "correct" ParBars have circuit#1 nearest the knuckle and "reversed" bars have circuit#1 farthest away. Recently, I was told this is incorrect, as James Thomas Engineering, arguably the originator of the modern ParBar, standards call for circuit#6 to be next to the knuckle. (Does this have to do with the fact that they drive on the wrong side of the road?) Every staggered break-out I've ever seen has circuit#1 the shortest, so shouldn't SixBars follow the same? Not a huge issue, but I've spent/wasted more time than necessary correcting paperwork and repatching the pin-patch due to this issue.

    I've always though one should be closest to the knuckle for the reason that on a stagered break out one was the closest and then they got longer.

    That makes the most sense to me, like you said, because that's how a staggered breakout is, and the six-bar is nothing more than a staggered breakout inside a piece of tubing with some lights on it.

    Same thing goes for breakout boxes, 1 is always closest to the pin.

    Though I agree with you, I'll point out that there are a lot of other things floating around.

    I have a venue (the older space) full of "tail #1 is long" breakouts. I have no idea why, or who supplied/spec'ed them, but there you go.

    *sigh*

    I've noticed that most sixbars seem to be uniform, but I never really thought it mattered. I don't see the world exploding if they're reversed.

    You're correct, the world didn't explode, just me. First, having to figure out which bars were wrong, then switching all the numbers 1 for 6, then repatching the racks. Lots of time wasted that could have been better spent on Control Booth.:p

    IIRC #1 is closest to the connection.

    Agree first closest to the knuckle as it were. Perhaps you got some lefties by mistake in having bars wired for closest on a bar to where they are powered from supply? Thomas wiring them in reverse... interesting if spec for them.

    There ALWAYS has to be that one company that must do it different... think Indian motorcycles, gas on the left, clutch on the right....

    [user]ship[/user], do you have any ParBars where you work?:rolleyes::lol: Are they all the same, with #1 nearest the knuckle?

    One shop has seemingly solved the problem by putting the knuckle in the middle, but the "tube" is 3"x4" metal raceway, with unistrut on the bottom for fixture mounting. Derek no like these at all.:( Wonder which of many companies to whom they originally belonged?

    Nope, don't have any that I'm aware of that are wired in that way in unless I mis-wired one or two while doing a re-work over the years. Remember some Soco 6-cell cyc lights I once did that to. Think I also had to re-wire them afterwards.

    Still curious in it more being a patching problem than real problem I can see in dealing with, or perhaps some custom gear left/right side of stage type situation one might have.
