What size receptacle needed for 166 amp 3 phase?
For a 166 amp 3 phase circuit, you would typically need a receptacle that can handle at least 200 amps to provide a safe margin. This would usually correspond to a 208V or 240V 3 phase receptacle with appropriate amperage rating, such as a NEMA L15-30 or L16-30 receptacle. It's critical to consult with a qualified electrician or electrical engineer to ensure the correct receptacle is selected for your specific application and local electrical code requirements.
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.
Does the neutral wire size and the hot wire size have to be the same on a 120v 208v bank?
If the load is perfectly planned AND purely resistive the neutral current would be zero in a 3-phase 4 wire circuit. But that is extremely rare. Before nonlinear loads (fluorescent lighting, computers, dimmers, variable speed drives etc) 1/2 size neutrals were often used but now full size neutrals are used to cope with the increasing levels of 3rd harmonics resulting from modern equipment, which can lead to neutral currents approaching or even exceeding the phase current. With very high levels or harmonics, double size neutrals are being used in places
Can you connect a 240V ballast to 208V line service?
It is not recommended to connect a 240V ballast to a 208V line service as this can potentially damage the ballast and create a safety hazard. It is best to use a ballast that is specifically designed for use with a 208V line service to ensure safe and proper operation.
How do you wire a 3 phase transformer to step up 120 to 240?
You don't. If the three phase power has one of the phases center-tapped as a neutral for 120/240 you can do it. This is known as quadraplex wiring. Without that neutral, you must have a transformer.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.

Can you feed a 208v 200amp panel from 480v 20amp circuit?
Not directly, you would need to transform 480v circuit to 120v with a transformer first.
Are 120V and 208V the same?
no 208v is bigger
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 average 208-230 voltage?
208V is one standard in the US for light commercial 3-phase power. It measures 208V phase to phase and 120V phase to neutral. 230 (or 240)V refers (in the US) to the common service supplied to residential. It is single-phase, with two hots and a neutral; 120-0-120. One hot and the neutral (120V) is used for receptacles and small appliances, both hots (240V) are used for large appliances, such as stoves, ovens, air conditioning, and water heater.

How do you wire a 208V motor with a 120V light bulb in the same circuit?
First off, I'm going to have to quore Robert here: (LIFE SAFETY WARNING! [disclaimer] Electricity is dangerous! You can be injured or killed! Improper installations can cause fire, injury and death! Should you be doing this yourself?) This is one of those questions - if you know this little, you shouldn't be doing what you are planning... No disrespect intended, but this is SO basic that it suggests you have not studied the subject at all! There are many good reference books and course books to study from. Unless you have 208V 3 phase power, you cannot make this work. You cannot power a 208V motor off a 120V supply. Since it is 208V, it is likely that it is a 3 phase motor. That means it has 3 hots. Check the specification plate on the motor, it should say how to wire it. With 208V 3 phase you should be able to get 120 from 1 hot phase to neutral. This means you need 5 feed wires (3 hots, a neutral, and ground) from your panel to your little light/motor contraption. Please buy a book and read up on this. It sounds like you don't know much about your system and ignorance is fatal (and not necessairly fatal to you) with electricity.

How do you measure amps on a 208V single phase circuit with a clamp on amp meter?
Clamp the meter around the energized conductor that is connected to the load to be measured and read the amperage off of the dial face of the meter.
What is the difference in amps used by lighting wired 277v vs 208v?
Answer for USA, Canada and countries running a 60 Hz supply service.Assuming you are using the same fixture, and assuming the fixture can operate on either voltage, you will get fewer amps with 208v than with 277v. However, a fixture designed for 208v will probably burn up on 277v, and a fixture designed for 277v will probably not produce any light on 208v.The two fixtures in reality are quite different. The 277v fixture is using one leg and neutral of a 277/480v 3 phase 4 wire system and the 208v fixture is using 2 legs of a 120/208v 3 phase 4 wire system.In commercial and industrial installations the 277v fixture is most common.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.
If you are making your own device and you bring in 208 3 phase for part of your needs - how can you properly tap 110 single phase from it to operate other parts of your device?
Your incoming 208V 3 phase power supply will also need an incoming neutral of the same conductor size. Then any single pole breaker installed in the panel will have 110 volts to the neutral. That is you can run 208V 3 phase motor circuits from a three phase breakers in the panel and any number of 110V circuits from single pole breakers.
