What is the difference between 460 or 480 volt?
The difference between 460 volts and 480 volts is 20 volts. They are not the same but all voltages have a nominal and a tolerance on each side of it. For example US household is 115 (or 117 or 118) nominal, and it can be between 110 and 120, or sometimes between 105 and 125 volts.
No, voltages in a wye configuration are not additive. Calculations for wye connection used the nominal voltage of 480 volts. The voltage of 277 volts is derived from the the phase voltage of 480 divided by the square root of 3 (for three phase) . 480 / 1.73 = 277 volts. For phase voltage of 460 the coil voltage to ground will be 460/1.73 = 266 volts.
Yes but the connection has to be to the 480 volt windings. Applying 277 volts to the 230 volt windings will damage the motor.
The voltage between each lead of a 480 volt three phase delta secondary is 480 volts.
No, the voltage difference is too much. A 570 volt motor falls in the 600 volt range which is separate from the 480 volt range of three phase systems.
480v 3phase is dangerous than 120v 3phase.
Yes, the 440 volt motor is withing the 10% voltage range of the 460 volt group. When the supply is said to be 480 volts, usually it is lower than what it is stated to be. Once the motor is connected check the current against the motor's nameplate amperage.
From about 480 degrees Celsius to about 460 degrees Celsius. There's not much difference, as you can see.
the motor having voltage rating above 480 volt is hv motors and motor having rating below 480 volt is lv motors. generally motor above 185 kw is hv or mv motor and motor below 185 kw is lv motor.
No. Not safe to do so. The distances between contacts may not be sufficient.
Can I run 480 volt , 60 HZ motor at a 380 volt , 60 Hz system?
In the United States, 480 Volts (AC) is a nominal system voltage before it is distributed to the device being powered. Line losses (measured in volts) occur throughout the distribution system due to current passing through wires and devices which have a resistance. Manufacturers of end use devices, such as motors, take this into account and list their devices as 460 volt devices. So, what this means is that you will see transformers and circuit… Read More
From 30 to 480 is a 1,500.0% increase.
Yes 480 volt electric wiring can be run in emt conduit.
In 480 volt 3-phase power supplies, each single phase lead has a voltage of 277 volts from lead to ground. There are 277 * square root of 3 (1.73) = 480 volts phase to phase.
480 volts and 60ohm impedence current = volt/impedence current=480/60 current=8ampeares
The electrical code states that a 50 HP 460 volt three phase motor draws 65 amps. The ideal amperage would be taken from the motors nameplate as different motors of the same horsepower will have different amperage's depending on what they are designed to do.
No. The voltage rating needs to be 600 volts for 480 volt power.
Across a 480 volt three phase system, 480 volts should appear across L1 and L2, L2 and L3 and L3 and L1.
No, that is too much.
The conductor for H2 connection on a 480 volt wire transformer should be marked:
Your question answers itself... 1000 watts, when operated on a 480-volt source..
If the cable is a 4 wire change the male and female ends to a 3 phase 480 with ground plug and receptacle
220 volt single phase from 480 volt 3 phase that one wire taken one phase and second wire connected in earth point. we get 220 v The above answer is incorrect, one phase from a three phase 480 volt system will give you 277 volts to ground. You must use a transformer to get the voltage you need.
with 3 phase lighting you do not have to use as large of wire and can use one neutral for every 3 current carrying conductors so it cut down on material costs ( as voltage increases current decreases) <<>> The voltage 277 is the star-point voltage of a 480 volt three phase system. By using a 480 volt wye system you have the dual ability of running 480 volt three phase equipment along with 277… Read More
Yes the voltage rating of devices is the maximum amount of voltage that it can handle. You could not use a 480 volt breaker on a 600 volt service and like wise you could not use a 208 volt rated breaker on a 480 volt service.
Crank the generator excitation up to 480 or down to 460. For calculations I used 480 volts. A 60kW generator at 480 volts will put out, kW x 1000/1.73 x E x (pf(.9)) = 80 amps. It looks like the machine that is to be run off the generator is a dual voltage machine. Not knowing the HP of the machine wire it to the 460 volt connection. The inrush current might be a problem… Read More
If building is serviced with 480 volts and you put a meter between ground and hot what will be the reading?
For alternating current, and assuming the supply transformer is properly grounded, you will have 240 volts to ground. 480 volts; single phase will have Line1 and Line2, both with 240 to ground and 480 across both Lines : three phase will have Line1, Line2, and Line3, all will have 240 to ground, and 480 across any two Lines. Same is true for 240 volt service, 120 to ground and 240 across. 120 volt service is… Read More
in the direct way no , you must use a converter
Yes, if you use a 240 volt to 480 volt step up 15 KVA transformer. This will give you 30 amps usable at 480 volts.
Most 480 volt lighting systems are operated through a lighting contactor. A smaller control voltage is used to control the lighting contactor.
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.
The motor sounds like a multi-voltage motor that can be wired either 230v or 460v depending on how the leads are wired. So yes it should be able to be hooked to a 3 phase 480v system just make sure you follow the wiring diagram for hooking the leads up to 480v. when a manufacturer list 230v it normally operates at 240v and the same for 460v operating at 480 volts
A 480 volt 3-phase power service is common in factories in USA and other countries which use 60 Hz ac electrical services. If you use the 480 volt service lines in the 'star' or 'Y' configuration you will have a central neutral point to connect a neutral line. You can then get a 277 volt single phase service by using one of the three phase lines along with that neutral.
To make this voltage change you will need to use a step up transformer.
How do you wire a roman weld transformer 120 kva 1 phase 440 volt from a 3 phase 480 delta-wye connection?
In a 480 volt wye connection you obtain two voltages, 277/480 volts. Any leg to grounded wye point will give you 277 volts. Between any of the legs to each other you will receive 480 volts. Any two legs of a three phase system is classified as single phase supply. From a 480 volt central distribution panel install a two pole breaker sized to the amperage shown on the welding machine. Be sure to use… Read More
Answer for USA, Canada and countries running a 60 Hertz supply service. The 277 volt heater can be wired to a single pole breaker in a 3 phase 4 wire 480 volt distribution panel. The breaker should be sized to the amperage draw of the heater. 277 volts is the star point (wye) voltage of a 480 3 phase system. 480 / 1.73 = 277 volts. The third answer is not correct, two phase legs… Read More
Add another leg of 120 to a three pole breaker.
No. It will probably arc over when it pops, this could weld it shorted.
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.
The star point voltage in a 480 volt wye system is 277 volts. 480 / 1.73 = 277.
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… Read More
277 Volts is derived from one phase of a 480 volt, 3 phase Wye wired transformer to the Neutral or grounded leg of the same transformer. Typically, 480 volt, 3 phase power is for commercial and Industrial use. If you have 120 volt power, you could, by means of boost transformers, increase the voltage to 277 or something close. However, I not sure that you will achieve the same result as with the afore mentioned… Read More
No, 277 volt fixtures are designed to work only on that voltage. 277 volts is the wye voltage of a three phase 480 volt system.
The utility company can provide a 480 volt, single phase service from a single phase transformer, usually with a three wire service. 480 volts is measured between the two line conductors, and 240 volts is measured between either line conductor and the common neutral conductor. The voltage of the line conductors are at 180 degrees with respect to the neutral conductor.
The temperature is 460 decrees to 480 decrees is also the hottest planet!
The 757's cruising speed ranges from 460 to 480 Knots
It ranges from about 900F to 860F (about 480°C to 460°C) at the surface.
Yes, all breakers have an insulation factor as to the maximum amount of voltage the device can be subjected to. A 208 volt breaker has a maximum up to and including 240 volts. A 480 volt breaker has a maximum up to and including 600 volts. A higher voltage rating breaker can be used on lower voltages but not the other way around.
No, it would overheat, might blow the fuse, otherwise it might catch fire.
