What does 120 277v mean?
120 277V means that the electrical system is designed to handle both 120 volts and 277 volts. This is common in commercial and industrial settings where different voltage levels may be required for various equipment and lighting fixtures. It allows for flexibility in power supply options.
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.
What percentage is 150 volts 0f 120 volts?
150 volts is 125% of 120 volts.
What is the standard voltage for wall outlets?
If you are talking about normal house hold voltage it would depend in which country you live in. For North America it would be 120/240 volts. For Europe and Eastern countries it would be 240 volts. Industrial voltages vary from country to country. These normal voltages range from 120, 277, 240, 347, 415, 480, to 600 volts.
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.
Will a switching power supply work on 277 volts?
Not unless it is rated for that voltage. You can likely find a step down transformer from 277 volt sto 120 volts.
Can you get 110 volts from 277volts?
The voltage of 277 is the wye connection of a 480 volt three phase supply. The only way to reduce 277 to 120 volts is with a step down transformer.
What potential will you have with 120 volts and 277 volts in same encloser?
The potential for someone to come along later on and get the wires mixed up causing damage to electrical appliances or lights.
What is a 277 volt fluorescent fixture?
A 277 volt lighting fixture is one that is usually used in an industrial application. The reason for this is the voltage rating. A voltage potential of 277 volts is the voltage to neutral (ground) of a three phase four wire 480 volt distribution system. 480 volts / 1.73 = 277 volts. Rather than having to add a transformer to the system to provide 120 volts for lighting, manufactures produced a ballast for fluorescent fixtures that operates on the 227 volt potential.
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.
How does 120 volts come from 208 volts?
208 is a three phase wye connection voltage. To obtain the each individual coil voltage the 208 is divided by 1.73 which equals to 120 volts. Hence you have 3 phase 208 voltage on the phase legs and 120 volts to the wye point which is grounded. This same formula is used on any 3 phase system. 600/347, 480/277, 208/120.
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 does 120 277v mean?
120 277V means that the electrical system is designed to handle both 120 volts and 277 volts. This is common in commercial and industrial settings where different voltage levels may be required for various equipment and lighting fixtures. It allows for flexibility in power supply options.
What is 50 percent of 120 volts?
50% of 120 volts = 50% * 120 = 0.5 * 120 = 60 volts
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.
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.
What percentage is 150 volts 0f 120 volts?
150 volts is 125% of 120 volts.
