The 208 volt configuration is one phase of a three phase source at 240 volts, where the 208 volt circuit is connected between the center tap of one 240 volt phase (usually a grounded neutral, in the style of a standard 120/240 split phase system) and the high delta connection on either of the other two phases.
208 circuit would consist of two phases of a 208 volt wye system or could be all three phases. The voltage between conductors would be 208 volts. The voltage to ground from any phase would be 120 volts. A 240 volt delta system would give you a high leg to ground, somewhere around 190 volts and the other two would be 120 volts to ground.
What else can I help you with?
What AWG cable for 200' x 208 volt three phase 250 amp circuit?
A wire size of 250 MCM will limit the voltage drop to 3% over a distance of 200 feet.
What size overcurrent protection device is required to protect the secondary of a three phase 75kva and 208 v transformer supplying a 150 amp continuous load?
If you're asking about load sizing, I think you already have the answer (at least 150A, although you could go up to 208 for full load, and maybe higher if you can overload the transformer). If you're talking about short circuit rating, you have entirely the wrong information. Short circuit rating will tell you if the fuse (if you're using fusing) mounting is rated to interrupt the available fault current.
What ways are there to convert 480 3 Phase to 208 3 phase?
It depends on your definition of efficiency. 480 can certainly push more power than 208 through the same size conductors, but it would not be efficient to wire a motor for 480 when 208 was all that was needed.
What is a circuit with no load?
An open circuit or a short-circuit (if that circuit is complete).
How is total KWH power usage calculated for a 208 volt 1 phase 60 hertz circuit drawing 24 amps per leg?
Single phase power from a L-L voltage of 208 volts is calc'd: P = V(phase to phase) * I (individual phase current) / sqrt(3) Total power from all three legs is the above P * 3. P is in watts; continuous sampling will result in watt hour measurements; 1000 x this is kWh's.
Why won't a 230-460 volt motor work on a 120-208 volt circuit?
Because its designed to operate at 230-460, not 120-208.
How do you get 208 on a single wire?
You don't. Every circuit needs a return wire back to the source.
What is the Power dissipated allowed by a circuit breaker with 208 volts and 5 amps?
1,040 watts or 1.04 KW.
Can you power a three phase motor and a 208 motor on the same circuit?
Yes, with the proper control equipment ahead of the motors.
How many wires do you need for a 208 v circuit?
208 v is a three-phase supply voltage used in North America, carried on a 4-wire system. The voltage between one of the three live wires and the neutral wire is 120 v and a single-phase supply can be taken by using one live and the neutral. If in doubt about the connection consult an electrician.
What is the approximate power consumed by a 10 kw heat strip rated 230 V when connected to a 208V circuit?
To calculate the approximate power consumed by a 10 kW heat strip rated at 230 V when connected to a 208 V circuit, we can use the formula for power: ( P = V^2 / R ). Since the heat strip is designed for 230 V, its resistance ( R ) can be calculated as ( R = V^2 / P = (230^2) / 10000 = 5.29 , \Omega ). When connected to 208 V, the power consumed will be ( P = 208^2 / 5.29 \approx 8.04 , kW ). Thus, the heat strip will consume approximately 8.04 kW when connected to a 208 V circuit.
What size wire for 225 amp 208 volt 3 phase circuit y.?
For a 225 amp 208 volt 3 phase circuit, you would typically need to use a 3/0 AWG copper wire or a 250 kcmil aluminum wire. Be sure to consult with local electrical codes and regulations to ensure compliance with specific requirements for your installation.
What are the specific electrical requirements for a 208/230 volt single phase appliance?
A 208/230 volt single phase appliance requires a dedicated electrical circuit with a voltage of 208 to 230 volts and a single phase power supply. The appliance should be connected to a properly rated outlet or wiring to ensure safe and efficient operation.
How many watts can be put on a 20 amp 208 volt circuit breaker?
20-amp breakers can be found for many different voltage levels. The higher-voltage ones tend to be more expensive. A breaker can be used in a circuit of equal or lower voltage than the rated voltage of the breaker.
What is 208 over 1000?
208/10 = 20.8 208/100 = 2.08 208/1,000 = 0.208
What is 60 percent off on 208?
60% of on 208 = 40% left of 208 = 208*40/100 = 83.2
How many square feet are in 208 feet x 208 feet?
It is: 208 times 208 = 43,264 square feet
