Is sj cord rated for 300 volts to be used for 480 volt?
No. The voltage rating needs to be 600 volts for 480 volt power.
Can you convert a 277 volt ac unit to 230 volt?
There in no quick and inexpensive way of doing this conversion. A transformer would have to be used and this type of winding is not common. 277 volts is the wye voltage of a three phase 480 volt system.
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.
How do you convert 277v to 120v for an outlet?
i think you just have to change the breaker from a 277 to a 120. 277 breakers are usually a 2 pole breaker and 120 is a single pole breaker. NO. 277v is not two poles, it is one pole, one single pole breaker in a 480 volt 3 phase system (typically). If you want 120 volts from a 277 volt source you need a step down transformer 277 volt to 120 volt , or 480/277 to 120/208 .
How do you wire a 277 volt heater from 480 volt box?
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 of a 480 volt system will give you 480 volts. It is the phase leg to ground (neutral) that gives you the 277 volts.A 277 Volt heater or device may not be wired to a 480 Volt circuit or box. A 277 Volt device may only be wired to a circuit rated for 277V/480V equipment.2 legs of 480 volts will give you 277. But since you don't know the answer you probably shouldn't be doing it! Please don't kill yourself, hire a licensed electrician.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-energizedIF YOU ARE NOT REALLY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
Wiring diagram to convert a 3 phase 480 volt generator to 277 volt?
You should not need a wiring diagram. If the generator has a star point (wye) connection then the phase voltage to ground (star point) is 277 volts. 480/1.73 = 277.
Is sj cord rated for 300 volts to be used for 480 volt?
No. The voltage rating needs to be 600 volts for 480 volt power.
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.
Should 2 legs of 480 volt 3 phase each have 480 volts?
Across a 480 volt three phase system, 480 volts should appear across L1 and L2, L2 and L3 and L3 and L1.
How do you get a 220 volt single phase from 380 volt 3phase synchrounos generator?
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.
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.
A 480-volt circuit has an impedace of 60 ohms what is the current?
480 volts and 60ohm impedence current = volt/impedence current=480/60 current=8ampeares
Can you run single phase 230 from one side of 480 volt 3 phase?
No, you will not obtain 230 volts. From a wye connected three phase 480 volt supply, 277 volts can be obtained from one phase leg and the neutral on the wye connection. 480 volts/1.73 (sq. root of 3) = 277 volts.
Can you convert a 277 volt ac unit to 230 volt?
There in no quick and inexpensive way of doing this conversion. A transformer would have to be used and this type of winding is not common. 277 volts is the wye voltage of a three phase 480 volt system.
What is the amps of a 5.5 kw 480 volt 3 phase?
Current in 200kw at 480 volts = 200,000/480 = 416.667 amps
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.
Will a 60kw generator that puts out 477v 3-phase power run a machine that requires 230460v 3-phase?
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 if the HP is high.
