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.
How many amps are available in a three phase 225 amp panel?
In a three phase 225 amp panel, there would be a total of 225 amps available for each phase, making it a total of 675 amps for all three phases combined. This means that you could have up to 225 amps of current flowing through each phase simultaneously.
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).
What is a 200 amp four lug panel?
A 200 amp four lug panel is an electrical distribution panel that can handle up to 200 amps of electricity. The "four lug" designation means that it has four terminals for connecting wires or circuits. This type of panel is commonly used in residential and commercial buildings to distribute electricity to different circuits.
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 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.
If two electrical loads are connected in parallel with each other and each load draws 6 amps what is the total current of the circuit?
The total current in the circuit would be 12 amps. When electrical loads are connected in parallel, the currents add up. So if each load draws 6 amps, the total current would be the sum of both loads, which is 6 + 6 = 12 amps.
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.
If a 240v circuit hsa 30 amps per phase what is the amperage 30 or 60?
If a 240V circuit has 30 amps per phase, the total amperage would be 30 amps. Since the current is measured per phase in a three-phase circuit, you would have 30 amps on each phase, totaling 30 amps.
Should the breaker total amps capacity be even on both side of the panel and if there are two breakers with the metal band connecting them together eached marked 30 amps is this a total of 60 amps?
In a typical residential electrical panel, it is not necessary for the total amps capacity to be even on both sides. The metal band connecting two breakers marked at 30 amps each indicates that they are being used as a 240V circuit, not as two separate 30 amp circuits. Therefore, the total amperage for this setup is still 30 amps.
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.
