What is the voltage rating of a motor on a 3 phase 4 wire 277V lighting circuit?
If the motor is a three phase the most likely voltage the motor operates on will be 480 volts.
What ways are there to convert 480 3 Phase to 208 3 phase?
It depends on your definition of efficiency. 480 can certainly push more power than 208 through the same size conductors, but it would not be efficient to wire a motor for 480 when 208 was all that was needed.
Display resolution for vga standard?
640 X 480
What size wire for 3 phase 15 hp 480 volt motor?
For a 15 HP, 480-volt three-phase motor, you typically need to use 10 AWG copper wire or 8 AWG aluminum wire for short distances, based on the National Electrical Code (NEC) guidelines. However, if the distance from the power source to the motor is long (over 100 feet), you may need to use a larger gauge wire to account for voltage drop, potentially 8 AWG copper or 6 AWG aluminum. Always consult local codes and a qualified electrician for specific applications.
How do you calculate 3 phase power for a motor that draws 22 amps per leg it is a 480 3 phase motor do you use 480 x 22 or 277 x 22?
1.73*480*22
What is the display resolution for iPhone?
480 by 320 pixels at 163 ppi
Can you wire a 3 phase 690 volt delta star motor to 480 volt 3 phase with out harming the motor?
Depends on the motor and the load on that motor. If the motor is loaded to its capacity, it will draw the same amount of power as it would on 690 volts - which will result in ( 690/480 = ) 144% of normal current, which will thermally damage the motor, or will trip overload protection.
I have a coolant motor with 420 volts in Lathe Machine but the supply voltage will be 480 volts. Can 420 volts 50Hz coolant motor can use in 480 volts 60Hz?
No, you'll burn your lathe motor up immediately. (it might last 30 seconds before it literally smokes.) You'll need to buy and install a "buck-boost" type transformer to drop the voltage from 480 to 420V. Best to have a qualified commercial electrician wire it up if you value your lathe.
What resolution is better 480 by 800 or 480 by 320 for cell phones?
480 by 800 will display sharper, smaller detail in pictures, but may take a bit longer to draw them.
What is a difference between hv motor and lv motor?
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.
Can you have 480 volt motor circuit in the same raceway with 120 volt control wire?
Yes, you can have a 480-volt motor circuit in the same raceway as a 120-volt control wire, but there are specific code requirements that must be followed to ensure safety and compliance. The National Electrical Code (NEC) allows this, provided that the conductors are properly sized, insulated for their respective voltages, and that any necessary separation or barriers are in place to prevent interference. It's essential to consult local codes and regulations, as they may have additional requirements.
Reverse direction on a 480 ac motor?
Reverse any two of the lead wires at the motor junction box.
