What is the output current of a 480 Volt primary 208 volt secondary - 3 phase transformer?
You need to mention the Load connected to find the current.
208 volt 12 amps versus 277 volt 6 amps?
It is hard to see a question here. Both of these voltages are currently use in electrical systems today. Both voltages are related to three phase systems. A voltage of 208 volts is a three phase wye system that has a voltage of 208 between lines L1, L2 and L3 and 120 volts between any of the lines and neutral. A voltage of 277 is the line to neutral voltage of a 480 volt three phase wye system. There is a voltage of 480 between L1, L2 and L3 and 277 volts between any of the lines and neutral.
Can you take a 120 volt ballast and use it in a 277 volt light?
Yes, if there is a 208 volt connection on the multi tap ballast. One side of the 208 to the common terminal and the other side of the 208 supply to the 208 volt lead. As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed. Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized. IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
How can you get a 240V single-phase power from a 120V 3-phase service?
First of all there is no common three phase 120 volt service. There is in North America a three wire 120/240 volt single phase service. That being said, if you want to change a 120 volt source to 240 volts it must be done with a transformer. Its classification is a step up transformer. The primary side of the transformer H1 - H2 will be connected to the 120 volts. The secondary side of the transformer X1 - X2 will be connected to the 240 volt load. The transformer is sized by the current required by the 240 volt load.
What gauge wire for 208 volt 95 amp 200 ft?
A #1 copper conductor will limit the voltage drop to 3% or less when supplying 95 amps for 200 feet on a 208 volt system. This size will allow the conductor to be loaded to 76 amps. 95 x 80% = 76 amps Conductors are only allowed to be loaded to 80% or their rated capacity. If you need the full 95 amps then you would need to use a wire with a rating of 120 amps. 120 x 80% = 96 amps. A 1/0 copper conductor will limit the voltage drop to 3% or less when supplying 120 amps for 200 feet on a 208 volt system.
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.
Can you operate a 208 volt on 110 volt?
The United States is one of the only places in the world that uses 110 volts instead 220 volts. In order to operate 208 volts on a 110 volt electrical current, you will need a voltage converter.
What is the output current of a 480 Volt primary 208 volt secondary - 3 phase transformer?
You need to mention the Load connected to find the current.
Will 120 - 277 volt electronic fluorescent ballasts work on 208 volts?
NO! a 120-277 electronic ballast requires one "hot" wire and a neutral from either a 110V or 277V supply. If you supply it with two "hot" wires from a 208 V supply, it will instantly burn up.Yes. A ballast with a specification range of 120 volt to 277 volt will work on 208 volt. These ballast use intelligent voltage sensing technology and it does not matter if the source is a hot and neutral or two (2) hots. Don't believe it? Call a ballast manufacturer instead of giving incorrect answers.

A voltage of 208 volts is a three phase wye system that has a voltage of 208 between lines L1, L2 and L3 and 120 volts between any of the lines and neutral. A voltage of 277 is the line to neutral voltage of a 480 volt three phase wye system. There is a voltage of 480 between L1, L2 and L3 and 277 volts between any of the lines and neutral.
What is a 208 circuit?
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.
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.
What happens when 240 volt equipment is plugged into a 208 volt source?
It should be ok
Do you need a step down transformer to run a 208 volt steam table on 240 volt feed?
Yes a transformer should be used. The steam table needs its correct voltage otherwise on 240 volts it will operate over its given specified nameplate wattage. A 208 volt heating element run off of 240 volt will have an output increase by 75 percent.
How single phase 208 works without a neutral?
There must be a 'return' connection if the load is to work. So, you cannot simply connect the load to the line conductor and expect it to work. It must also be connected to the neutral. In some circumstances (e.g. with no ground-fault interrupter installed), it will also work if you connect it to earth (ground) instead of the neutral, but this will contravene most electrical regulations and should NEVER be done.
What is the voltage of house current is it 208 v?
208 v three-phase supplies are an option for American properties, because the line to neutral voltage is 120 v.
How do you tap off of a 480 volt disconnect?
You don't. You hire a qualified electrician who doesn't need to read this page for the answer. That said, if you are merely curious as to the methods: "480" Volt will be 3-phase with either Delta wiring (480 phase-to-phase, NO neutral), or Wye wiring (480 phase-to-phase, and 277 phase-to-neutral). You can use this directly, to run three phase equipment from all three phases, to run equipment at 480 from just two phases (being careful to keep loads balanced), or to run lighting circuits from the 277-to-neutral (being careful to size the neutral conductor carefully). You can also step it down to "208", which will be 208 phase to phase and 120 phase to neutral -- "standard" line voltage. But seriously, if you need to ask the question, you SHOULD NOT be touching 480 switchgear and wiring, for the safety of both yourself and others.
