Trying to calculate how many amps a 480/277volt 3phase 200 amp panel can handle total,is it 200 amps each leg or 200 all together would like a simple answer please
The answer is 200 amps @ 480v 3 phase.
Or...
166,000 watts
So the total amps this panel can handle is 200. So if I count all the breakers in this panel it can not exceed 200 amps.Quote:

So we can get a better idea of how to help you what is it you are looking for? Why are you asking this?
I have a tenant who says he needs 1200 amps and 480/277v 3 phase in order to move in to the suite and I have 2-200 amp 480/277v 3 phase panelsQuote:

Unless you have outside agents to handle these things for you, if you are the landlord/owner you really need to know specifically what you have to offer.
Be sure to get from the tenant exactly what there load will be.
Do they need a 1200 amp service or do they have 1200 amp load?
Service needs to be loaded no more than 80% of it's rated capacity. So, a 1200 amp rated service can handle no more than 960 amps.
If the load truly is 1200 amps, then a 1500 amp capacity service is needed. 1600 Amp equipment is a standard size.
Landlords and/or property managers usually have an electrician or an engineering firm on retainer to advise owners of electrical ratings of tenant spaces.
This is so when the space is advertised, prospective tenants can know right away if the space has adequate electrical capabilites.
Tenants in turn should also inspect a space with professional advice to be sure the space meets their needs.
Clearly, with only 2 - 200 amp panelboards, and a tenant that needs 1200 amps, this space will not meet their needs without upsizing the service.
I didn't ask you for all your other opinions all I asked is it able to handle the load or not all your extra typing you still didn't answer the questionQuote:

I'll answer your question as stated. Your two panels will not handle a 1200 amp load... period.
Where are you located? If a renter over here needed 1200 Amps, Authorities may think he is growing something, and a lot of it.
Are the Loads mostly Refrigeration?
I think after over a year this is all taken care of, don't you?Quote:

I think they quite CLEARLY answered the question at hand.
You HAVE TWO 200 AMP PANELS. This equals a TOTAL SERVICE OF 400 AMPS
Henceforth do the basic math 1200 MINUS 400 equals 8 HUNDRED AMPS LESS than what the tenant is requiring. But factor in that you cannot within code overload service unles you'd like your property burned to a pile of dust so you will REQUIRE 1,600 AMP SERVICE TO ACCOMIDATE THIS Tenant. That is a one thousand four hundred amp diffrence.
You have to weigh the pros with the cons. You'd most likely be mandated to upgrade ALL WIRING on the premesis or at very minimum the main feed and meter, add additional branches to accomidate the load and so forth.
Its frustrating yes but you cannot argue with stone hard cold fact.
What kind of place is this a factory? Ususlly most normal office spaces do not require nearly as much amperage. The apt. complex where I live at where the power is included in tenant rent has 63 units plus the office common areas, elevator, maintenance shop, as well as a garage and carports and lighting outdoors. So the service to this place is probobly exceeding 8 thousand amps. But it's the top mains that come to the building(36,000 volts give or take) somewheres on the line transformers break down that into 120/240 most likely after the meter I don't know never asked I could though.
That's all there is to it.
You REQUIRE 1600 amps.
My apologies I mean one thousand two hundred amp diffrence my mistake. I'm new here do not know how to delete and redo posts here lol.
I think after over three years this is all taken care of, don't you?
