Okay Electrical Wizards, this one's for you (???)

Do the math!

what math? You test phase to phase on 2 wire connected to the same phase on the load side of anything you will have 0 volts. Story doesn't check out. You may be not telling the story right.

Could it be that the lug on phase B wasn't making a dead short contact to lug C. That there was some kinda of airgap or oxidation or just not enough contact that caused resistance to the current flow? Than the Phase C to B voltage reading was across that resistance?

Of course you DO know you have a ground reference in all of this, right????

I really don't feel like arguing this little question much more, honestly.

I'm tired.

It was just intended to be a fun question. I'm not going to get into some debate over it.

I was there, no one (well, few) else was.

Don't believe it...fine. I'm not sure I really care at this point.

Best.

We had designed a air conveyor for plastic pellets. We used 3 inch dia. aluminum tubing. We sent grounding wires with the unit, but the installer chose not to use them. When they started the system it started throwing sparks from the static that it generated.

I went on a ambulance run once in the middle of nowhere where the call was someone electrocuted.

Two guys had found some old railroad telegraph lines and tried to steal them for the metal.

The lines were not down and the wind was blowing about 50 mph.

The wind had built an very large static charge that had knocked down and knocked out the guy that had grounded the wire through his body.

He survived but took about 6 months before the nerve damage from the shock cleared up.

It also took him about 6 months to get out of jail.

LOL...just like helicopter rotors.

Look out!!!

Double post

We believe that the electrician who made up the connections didn't torque the lug properly. Then when it was under load and heated up the conductor came loose and ultimately came free. That electrician lost his job.

And now you know...the rest of the story.

Damn right he did. wtf!

I've actually seen those lugs arching from being loose as well, vibration and all. Maybe he was too lazy to go grab the proper Allen wrenches, or didn't have the right size. smh

That is some scary stuff, glad everyone is ok.

The house I bought had a well pump wired 120V with 14 AWG which toasted the insulation. I'm going to have to call my electrician friend over before I try to install anything that needs anything like a high leg delta circuit.

cool thread....my power company crew decided to replace my wire past the meter to the main breaker the idiots

my flickering lights got worse.....this was in the dry Texas summer....I saw sparks dropping to the dry grass that went for miles.....stripped lug

I had to tell someone.....thanks....lock my main breaker.....

I was in a Navy helicopter squadron in the 80's. When the aircraft was landing at night you could see a spark jump from it to the flight deck.

What we got here is a byzantium delta reconnect/redirect circuit rigamaroo reEnergizing all it's losses- Well Splicketly Splack now I'll say is this hare a Independent Self Powering System for Free Energy?

I don't know Gus Gus...I think it's tapping it's own main vein to redistribute a positive gain feed back perpetual loop de loop of some end which is everything it's powering.

yeah...that's the ticket...you burn it up into ash and it keeps on appearing in a different form. One's Blue, The Other's Red and Yellow Sometimes Rather.

But Sometimes late at night I can hear the crispy crawling exoskeletons and what can only be the beast which no one knew how to slew but could reckon with notions of never been done so far.

That's when I got the Golden ticket and put into the fax machine to send it on time for my Bankroll Lottery Death Bed Motorcade.

All in time for the Birth Of my Baby Tesla Spearhead God Resurrection Kill Joy Dream Beam Correction Team to be Born Again.

Yeah...so the suspense is killing me and I Truly Don't Know but Good Luck with Electricity or Eccentricity too! Hopefully You have an invention or advention there at your disposal or proposal.

LOL!!

Wow...I don't know, but that's one creative piece of writing, that's for sure!!

I can think of no less than 100 threads here on ATS this could be cut and pasted into as a response!!!!

Good job!

480 volts from B stopped with an open and ground of 277 feeding back into B for a better ground around the open...

Sounds like B and C had a cross-phase together, so every other cycle was shorted and causing the lead to run its excess energy into the ground? Spider webs conduct electricity, any of those around?

That electrician lost his job.

Poor bastard.

It was probably his last task of the day and he was just looking to get out of there and grab a pint.

Can't do that though...not when it's important like this.

The more that a task becomes routine, the greater the chance for human error.

When you're working on systems like these, which 100M dollars per day depend on, there are zero excuses.

And this was just one of our smaller data centers too. Our big centers are 1.5mW/each.

However, in this particular case, we'd had numerous systems fail over to this particular data center due to maintenance ops on other centers, so it was particularly problematic. And, it was the load which caused the issues.

"Poor batard"...well, he knew the game going in...and he made the mistake. So...no prisoners.

Unfortunate...yes. Excusable...no.

edit...it was a $157,000 / year job! Not just an entry level apprentice position. POOF!!

you aint seen nothin yet.
chk out power generation vs power usage anywhere in the world. where is the excess power coming from and who triggered it?

cheers

Torqued some small by comparison 3/0 lugs the other day, gave them a good 45lb/ft. Then second time with the inspector...

Dealing with that thick stuff would take quite a bit of force to torque properly.

Can imagine when dealing with equipment at that level every lug and mounting bolt should be torqued and documented as part of procedure. Seems the blue paint manufactures put on them would be useful also.

Before reading anything further than your post, I'm going to say the only way this is possible is that somehow B and C were actually being fed by the same phase. You had three "hots" that way but only two phases. Now I'' read further and see if I'm correct.

Solid wire pisses me off for this exact reason. Coming from fine strand welding cable, car audio etc, solid wire is not even safe to use. You cant get most terminals tight enough to satisfy basic common sense instinct. It should be fine strand, hard insulated and LUGGED.
