Can you get 120 volts from a 480 volts 3 phase Y generator?

NO, the 480 Volts Y -- is 4 wire system, with three wires which are hot legs @ 480 volts between each three hot legs. A mid tap is a neutral leg (ground) the white wire. Which gives 277 volts between it and any of the three hot legs. so a 4wire 480 volt Y system. Gives 480 /277 volts.

What voltage reading would you get from a 277 480 volt system?

From a three phase four wire distribution system the voltages would be as follows. From L1 to N - 277 volts. From L2 to N - 277 volts. From L3 to N - 277 volts. From L1 to L2 - 480 volts. From L2 to L3 - 480 volts. From L3 to L1 -480 volts.

What is the required wire size for a 230 feet run 480 volt 100 amp?

Depends on length. The more length, the more resistance.

Can you run a 480 volt machine with 600 volt incoming voltage?

Yes, but the 600 volts would have to be transformed down to 480 volts. Direct connection to the motor with 600 volts would overheat the motor to destruction.

What size tech cable for 480 feet 100 amp?

This is a voltage drop to establish wire size question. For a correct answer to this question two values are needed. One value needed is the voltage and the other is whether it is three phase or a single phase installation.

How do you come up with 277 volts?

The star point or wye voltage of a 480 volt three phase four wire system is 277 volts. The 480 voltage is divided by the sq root of 3 (for 3 phases). The sq root of 3 is 1.73. 480 volts/1.73 = 277 volts. The same formula is used on all three phase four wire systems. 208 volts /1.73 = 120 volts, 416 volts /1.73 = 240 volts, 600 volts / 1.73 = 347 volts.

What is the required wire size for a 230 feet run 480 volt 100 amp?

Depends on length. The more length, the more resistance.

What is the volt drop on a cable 912 meters 480 volts and load of 54 amps?

The volt drop on a cable 912 meters 480 volts and load of 54 amps is 5% if you use 2/0 AWG wire and 2.4% if you use 300MCM wire. See Related Links below

Is 277 volt one hot wire?

No, 277 volts is the line to neutral of a 480 volt wye three phase system. L1- N, L2 - N and L3 - N will give you 277 volts. L1 to L2. L2 to L3 and L3 to L1 will give you 480 volts.

If building is serviced with 480 volts and you put a meter between ground and hot what will be the reading?

If you measure the voltage between the hot wire (480V) and the ground using a meter, the reading should be close to 480 volts. Ground is typically considered to be at 0 volts potential, so the voltage difference between the hot wire and ground should be around 480 volts.

Why isn't everything rated at 480 volts?

Not everything needs to be. Many standard wire insulations are rated at 600 volts, some 300, and some are more or less. It would be cost-prohibitive to have everything rated at 480 volts. Especially things designed to operate at 120 volts. Things rated for 480 but running at 120 would be physically larger than necessary, and therefore more expensive. If you're wondering why everything doesn't just run at 480 it's because it's not safe for residential applications.

What gauge wire should be used for a 480 volt 100 amp run of just under 100 feet?

For a 100-foot run of 480 volts at 100 amps, you would typically need a 3/0 AWG copper wire to ensure safe and efficient power transmission without significant voltage drop. It is recommended to consult with a licensed electrician for a detailed calculation based on specific factors such as insulation type, ambient temperature, and voltage drop tolerance.

What is the primary amps on a 25kva tranformer with input volts 480 Volts AC?

if it's single-phase, 25,000 divided by 480.

What is the difference between a 2- pronged cable and a 4 - pronged cable?

2 prong is a hot and neutral and a 4 prong is a 3 phase with a ground wire.3 pole 4 wire meaning 3 hots could be 240 volts or 480 volts

Is sj cord rated for 300 volts to be used for 480 volt?

No, SJ cord is only rated for 300 volts and is not suitable for use with 480 volts. It is important to use the correct voltage rated cord for safety and to prevent damage to equipment. Look for cords that are specifically rated for 480 volts.
