FINALLY HE GETS IT!!! Instead of trying to answer questions that he's not qualified to answer, he ASKS a question to further his knowledge! We can only hope that this is the start of a new trend for Dido! Good going Dido! Are you seeing this, Stormy?? It would be really nice if we could get the both of you to understand this concept!

Ya, nice posts, Jake!
Call it what it is....a Corner-grounded Delta. If you look inside the disconnect you'll see that A and B phases have normal fuses. The C phase will have a "solid neutral" which is basically a piece of copper tubing with a UL sticker on it. If you look closer you will see that that phase is taken to ground, which is why you were measuring 0 volts to ground on that phase....because its already grounded.
Shoot. They gotz all kindaz 3 phase run capacitors. Start Capacitors too. They've just made them real small for the motor. They internally mount them so you dont have to look at that bulge on top of the motor. Bubba
Jake Thank you ! for your input and explaining to my question From Dido
All of others that like to criticize go suck on egg
Sorry but not in this case From Dido
No you get it that can tell differeance between my bottom hole and your NOSE
We'll be giving Dildo a Minon card by the first of they year if he keeps this up...
Get the popcorn. We have a couple of BRILLIANTS starting a discussion here...
Ditto, Thanks Jake and thanks Oscar

Dido says "go suck on egg" I think that places his origin in a Slavic country?
go suck on egg
Typical response from you Oscar_Sucks......no technical discussion whatsoever. What's the matter Oscar? Still peeved about how I've shown repeatedly how you and your butt buddy fellow minions are complete idiots when it involves the electical requiements of the very equipment that you install? Or is it just that the topic is over yer head? Have you and Boy Paul figured out the difference between MOP and MCA yet?
Hey Volts:
You are obviously a wanna-be EE, but more likely an unlicensed electrician operating out of a Pinto Stationwagon. Your self-promotional behavior, along with your need to be the recognized expert are just symptoms of your sociopathic tendancies. My guess is that your mother was a w**re or a crack addict, and you were taken away from her at a very young age and raised in foster homes and state institutions until you were 16. Your lack of bonding with a parental figure as a toddler is quite obvious.

Geeze... I get busy for a couple of days and you guys go nuts on Volty.
Volty and I have had some debates in the past... and rarely agree. This is another example of that.
Volty immediately made the assumption this system was a corner-grounded delta. In my business, I can't afford those kind of assumptions...
Corner-grounded deltas are around... but they're most likely in older facilities that, in trying to comply with new code... have grounded their floating delta systems. For the un-initiated, this is done to insure a quick circuit (fuse) clearance in the event of a ground fault.
I've never seen this done on a smaller system (less than 500 kVa) because it's usually cheaper just to upgrade the whole shebang.
Dido said (I think) this was a separate 3 phase service for running a couple of 25 hp compressors. That should be somewhere around 70 kVa.
Anybody throwing that together would use a open delta because it's cheap.... 2 transformers instead of three.
In certain configurations, especially if the service only provides 3 phase (open deltas are great for single phase services too) one phase will float ground potential all over the map...

You know my ex wife don't you.
Damn Oscar, you can make a contribution! Now go insert that treatise of your's in the charter for alt.hvac and you'll have a perfect description of the majority of puds in this NG. I merely respond in kind, so, if you perceive me that way, my job is done, as you're only getting back what you give.
That's OK, Volty can hold his own with you chumps.
Then get your head out of your ass, Jake. What he described was nothing but a Corner- grounded Delta. Is this NOT what he wrote?:
"when I measure the supply source across the phases the supply I found 440 plus and minus couple volts which was some what reasonable then I measured it to ground and found surprise two legs (phases) are 440 to ground and one at ground potential: what kind system is this? Transformer is next to the unit."
It's very clear that one of the phases is solidly grounded. What's that make it Jake? Evidently you assumed that it was an open delta. Since you did not state whether it was corner grounded or center tapped, by default it was then an ungrounded open delta? Seems that you incorrectly assumed it was an open delta.....and you can't afford those kind of assumptions in your business? How about flat out errors?
Who's assuming now, Jake?
You call that great? A closed delta would be much more stable.
You married the bitch too?
Wrong, I don't give a shit, but you are spouting tons of it...
