Re: Do I have 3 - phase power? (danielm3)
Founds this on a site: "Most industrial three-phase voltage supplies are either 480 volts or 277 volts RMS, compared to 120 volts for residential usage."
I found out I do have 480 volts to my shop, with the 4 wires I have in my box I think i do have 3 phase power.

Re: Do I have 3 - phase power? (danielm3)
there is a converter that you can get my parents have it in there ice cream shop to run the big machines i think that they cost about a thousand each. i dont know if thats what you are looking for but just to let you know its an option.

I have a converter that I would sell you for $250 . I bought it for $600 2 years ago to run some vaccum pumps for infusion and went to smaller pumps and did not need it anymore. It only has 2 hours on the machine.

Re: Do I have 3 - phase power? (danielm3)
Yess.
it's an old shitty box you got there.
DO NOT DO THIS UNLESS YOU ARE FAMILIAR WITH ELECTRICITY, 600 VOLT CAN KILL YOU QUICK, JUST A SHOCK AND YOUR DONE FOR THE OSPITAL. CALL AN ELECTRICIAN IF YOU ARN'T FAMILIAR WITH ELECTRICITY.
you can check with a multimeter ( just be shure that your multimeter can handle the power )
look between the black and the red = 600 Volt ac
look between the red and orange ( btw, this is supposed to be blue ) = 600 V ac
between black and GRND = 347 Vac
RED and Grnd = 347 Vac
orange and Grnd = 347 Vac
you can get a little disbalance depending on what your box is running right now. example, if your shop light are all on the same phase, you will read a little lower ( EX : 347 Vac ) on this phase.
AGAIN : DO NOT ATTEMPT THIS IF YOU DONT KNOW ELECTRICITY.
be careful with that, too many people are getting killed by electricy each year thinking that this is just some power...

Re: Do I have 3 - phase power? (danielm3)
u do have 3 phase as the 2 breakers on the right are 3 phase breakers and one is obviously wired up. check to see what the voltage is running between two of the hot legs.
besides all that... where the hell is the main!? i second the fire-hazard comment as well...

Re: Do I have 3 - phase power? (bigTom)
Thanks a lot guys! Yeah this is an old building and the pannels are old and there is no way I am touching any of those wires ahah

Actually... 600-volts wont kill you. its amperage that kills. And as for the "comon" 3-phase powers your all wrong!
3-phase power can come in any voltage, in a standard building you will find it in 220, 440, or 880 volts. 277-volt setups are 99% ALWAYS in hospitals, because in europe and japan 277-volts is comon use for medical electronics. so hospitals run 277-volt to run there electrical equipment from overseas. Now almost anything is available in 277-volts for hospitals tho, even lighting fixtures. But like i said you will 99% only find it in a hospital.

yhea, well sorry I'm not an international electician... I work in Canada, come over here, I'll show you that 347 V ca is mesured between Ph and Grnd, we only have 1 way to get power in Quebec, ,it's with Hydro-Quebec, wich deliever 347-600. wich is transformed from High tension line wich are a 25 000 Volt Ca. Often they used gel transformer. you can get your own dry tapp if you want to convert in your own shop. I didn't get a look at where the owner if this tread live, I assume this as my mistake but anywhere you get near 600 Volt between phases you will get industrial machine to work.
and btw, when you get a shock on the primary of a distributor transformator, you will get killed, the only currrent limiting device is the Main fuses in the pillar outside, limmiting like 3 x 25 or 50 KVA into your body witch mean that you can get ALL the power potential of the shop into a single shock.
if you think you are solid enough to handle 600 Vca at 200 Amp. let me know, I'd like to to.
I personnaly took 347 at 35 amp last year and had two holes burned in skin, one in the hand the other on the elbow,
dont expletive around in those box if you don't know what you are doing despite the fact that some think it's just power again, it can kill you, and this is no discussing point.
10 Milli amp, in the right spot of your body can get your heart to beat anormaly ( dunno the english word for défébrilation cardiaque ... )

your funny, your telling people they're wrong and really don't have the knowledge to do so, for 1 220v is only available in single phase systems, and 2 almost any office or other commercial building run the lighting systems off of 277v, its not just in hospitals, i work with 277v everyday. in fact 277v is the most common voltage known kills electricians. stick w/ flanges, and think before commenting on things you have no experience with, there is already enough of that going around here.
Thats not looking to safe, i would put the cover back on and call a licensed electrician. what are you trying to accomplish that you need a converter?

The cover is always on, i took it off to take the picture. I bought something that needs 3 phase power so I was just wondering if I had it or not.
I've had a licensed guy come here a few times to wire up some other stuff, forgot to ask him about the 3 phase thing. He said you have a very old board and nothing else.

Re: Do I have 3 - phase power? (danielm3)
you have 3 phase. it looks to be 120/208 volts. 277/480 volts is hi voltage and can kill you pritty fast. that panel is a fire hazard. fpe panels are junk. if you need a breaker its going to cost you an arm and a leg because they dont make them any more. it going to be hard to find as well. pm me if you have any more questions. im a master electrican in md

Re: (danielm3)
My 20" sander is 220 3 phase .Thats how you make an AC motor go both directions. Any AC motor that rotates in both directions is 3 phase.
Ands there is DC motors that have AC converters like electric drills and stuff like that ,That rotate both ways.
And by the way NO thats not a 3 phase box. 3 phase has 4 big cables in the top .

that panel is typical looking for older industrial buildings. i have 9yrs in the trade and ive seen em all. its not too bad. and as for the main breaker.... that is a main lug panel meanin that the meter is more than 15 feet from the panel out side and the main breaker is in the meter socket on the outside of the building.

Re: Do I have 3 - phase power? (danielm3)
Well.
Here is my answer after drinking a bit.
Yes you do have 3 phase power (absolutely positively for sure).
Here is where it gets confusing…….
Here in the US we have a bunch of choices. Three phase services come in multiple voltages (120,208,240,277,480,600,and higher) and the windings of the transformer that feeds your service can be delta or wye (I can explain it if you really want to hear about it).
My wild *** guess it that you have a grounded Delta 120/208/240service (which provides you with two 120 VAC legs, one 208VAC leg ”the stinger leg” and 240VAC three phase power) . You can check this out with a voltmeter. If you apply one lead of your voltmeter to a grounded wire, then apply the other lead to one of the three wires in the top of the panel you should read voltage as follows. Black wire on the left to ground 115-125 (120) VAC, Red wire in the middle to ground 115-125 (120) VAC, Orange wire on the right to ground 200-220 (208) VAC.
Then carefully apply one lead to the black and the other to the red wire, you should read 220-250 (240) VAC, and you should also read the same measuring black to orange and orange to red.
The other type of service you could have is a Wye. If that is the case you have three 120 VAC legs, and 208VAC three phase power. If this is the case the voltage reading from the black, red or orange wire will be the same (about 120 VAC), and if you measure between any two of the three wires you will measure about 208VAC.
What you have will work perfectly with your mill. Looks like you have an unused breaker in the bottom right of your panel, which should be perfect as long as it is the correct ampacity. If it isn’t right you may be able to call around if you live in an urban area and find a retailer of used electrical equipment. They may allow you to trade your breaker for free or a small fee to get one with the correct amp rating for your mill (probably 20-30 amp). Anyway, get some good local help, or pay a decent contractor to do the work, it isn’t worth doing it yourself if you are unfamiliar with electricity.
Good luck,
