Depends upon what you're "reading", but that would certainly be a slightly higher than normal reading on each leg, as long as it is LESS than 200 amps!
You would generally want no more than 160 amps, which is 80 percent of max.

How do you wire in for two dryers?
You need two separate 240 VAC circuits from your electric panel that are each rated at 30 amps if they are electric dryers.
What is 7kva in amps?
In a standard 3 phase system in North America, 7kVa would be equivalent to 19.5 amps on each phase. The equation is: 7kva*1000/208v/1.73=19.45 amps (3 phase)
Can the Craftsman 73755 amp meter take accurate ac amp readings without separating the hot and neutral wires as the older catalogs stated?
A clamped- or forked-type ammeter can only measure the amps in one conductor at a time. Using it as you suggest would get a reading of 0 amps. This is because the reading of one conductor's amps cancels the other conductor's amps. Ammeters of this type actually measure the rise and fall of the magnetic field produced by the AC current. Since electrons in one conductor are moving the opposite direction of the other conductor, the magnetic fields cancel each other. On DC circuits, since there is no rise and fall of the magnetic field, it is constant, these type ammeters always read 0 amps on DC current.
What do you use a clamp meter for?
The clamp part is for measuring amps via induction. You set meter to amps and clamp around only a single wire. Device you are measuring must be operating. This means you couldn't clamp around a lamp cord to a table lamp since the current induced in each direction cancels out. You would have to separate the wires. An electrician would carry a short extension cord with the wires already separated. Most often a clamp meter is use to checks amps in a breaker panel on the black wire coming from the breaker.
Is it necessary to balance a house fuse panel to save electricity and if so why and how is it done?
A balanced house panel should be the ultimate goal. It will not save you electricity as the watt meter on the house monitors the use of power from both legs of the incoming power. To balance a panel you want the current from L1 to Neutral to equal L2 to Neutral. The neutral carries the unbalanced current between L1 and L2. A perfectly balanced panel will have no current on the neutral. It is done by knowing what the current draw is on every breaker. Then they are physically positioned so that they equal each other on the opposite leg. e.g. breaker 1 on leg L1 = 5 amps, breaker 2 on leg L2 = 10 amps, breaker 3 on leg L1 = 10 amps, breaker 4 on leg L2 = 5 amps. Total up all amperages on L1 and then on L2 , if they are equal then the panel is balanced with no current on the neutral.
What is a 200 amp four lug panel?
An electrical panel for 3 phase power with three hot connections and a neutral bar. It's capacity would be 200 amps on each of the three legs.
Are there 100A available on both bars of a 100A panel in a home and for instance can you draw 75A on each bar?
The amp rating of a panel is based on the size of materials used (the bars, etc). You can pull 400 amps through your panel (provided a 400amp breaker was in place); but it would probably melt down very quickly. Basically you have 100 amps total to play with: be it from two 50amp breakers or 30 subpanels pulling 3 amps. :D You just can't pull more than 100amps at one time or the main will trip. The 100 amps is a rating for each bar. If your panel has a 100 amp double pole breaker, then you can use up to 100 amps on each pole. You really shouldn't draw more than 80 amps continuously. But you can count on having that 160 amps avilable if all your loads use only one hot leg of the panel (120 volt loads instead of 240).
How many circuits are on a 150 amp panel?
As many as needed; panel capacities are different from each other in amps and space. there should be a sticker on the door of the panel that tells of how many breakers can be installed in that panel. regarding the amps, a load calculation can be made to determine the full load used on such a panel.
How do you wire in for two dryers?
You need two separate 240 VAC circuits from your electric panel that are each rated at 30 amps if they are electric dryers.
How many 50 amp outlets can you run off a 125 amp main panel?
It depends on duty factor of each connected device. For a continuous load you can support 80% of 125 Amps which is 100 Amps. That would support two 50 A breakers each supporting a 40 Amp continuous load. If your loads were less and not continuous you can have more breakers. It is all a matter of supply and demand.
What is 7kva in amps?
In a standard 3 phase system in North America, 7kVa would be equivalent to 19.5 amps on each phase. The equation is: 7kva*1000/208v/1.73=19.45 amps (3 phase)
Is it safe to have 200 plus amps in breakers inside than 90 amps on the main service breaker outside?
I am assuming by your description that the panel is protected by a 90 amp breaker and the breakers in the panel when added up is 200. This is okay as long as your 90 amp breaker trips on a regular basis. It is typical for the breakers to add up to more than the main breaker under the assumption that you would rarely be running each circuit at its maximum capacity.
How many amps on 3 phase 225 amp panelboard each phase?
It means 225 amps on each phase.
What would make the main breaker blow instead of the single breakers?
The sum of the breakers in a panel exceeds the rating of the main breaker in almost all applications. This is because of the design usually anticipates that all devices won't operate at once or at full load. So if you had 100 Amp service and you had ten 20 Amp breakers each happily drawing 15 amps that would be 150 Amps and the main would trip. You need to heavy up your service.
