What else can I help you with?
What voltages do industrial electricians work with?
480 volt amperage and up to higher voltage
What is 108 as a fraction of 480?
108/480 or 9/40
How many amps will a 3 phase 480 volt 4kw heater draw?
To calculate the amperage drawn by the heater, you can use the formula: Amperage (A) = Power (W) / (Voltage (V) * Square root of 3). In this case, the amperage drawn will be approximately 5.8 Amps.
Can you run 480 volt motors in a 380 volt system?
Can I run 480 volt , 60 HZ motor at a 380 volt , 60 Hz system?
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 the input current and not the output current to find the correct feeder for the unit.
Can 480 volt electric be run in emt conduit?
Yes 480 volt electric wiring can be run in emt conduit.
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
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.
Will a120 volt meter blow up if installed in a 480 volt installation?
Yes
What color should a H2 Conductor on 480 volt transformer should be marked?
The conductor for H2 connection on a 480 volt wire transformer should be marked:
Can you connect 460Vac motor to 480Vac circuit?
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.
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.
