Why 380 volts line to line if connect line to neutral is 220 volts?

A voltage of 380 volts is a three phase voltage. On a three phase four wire system, each phase leg to neutral (grounded) will give you 220 volts. This voltage is obtained by dividing the phase voltage by 1.73, as the phase legs are generated 120 degrees from each other. Square root of three is 1.73 divided into 380 equals 220 volts.

How do you hook up a water heater with red black and white wires?
Sounds like it is a 220-240 Volt hot water heater. The black and red are connected to the 220 volts supply and the white is connected to Neutral. At the breaker panel red and black connect to the 2-pole 220 volt breaker and white goes to the neutral bus bar.
What is voltage phase to phase 380 3 phase?
let me clear difference between phase voltage and line voltage. phase voltage is measure line to neutral and line voltage is measure line to line.there is correct answer that 380 volt is sum of multiply of square root 3 to phase voltage 220 volt.phase volt line volt220 volt x 1.732 = 381 volt230 volt x 1.732 = 400 volt240 volt x 1.732 = 415 voltM.

How many wires needed for 220 volts ac though emt?
Two wires are needed for 220 volts.
What is the Household wiring color code?
On a 110 volt circuit, Black is hot, White is neutral, Green or bare Copper is ground. . Connect Black to the gold screw, White to the silver screw, and bare copper ground to the Green ground screw on the receptacle. On a 220 Volt circuit Black & Red are both hot, each carrying 110 volts for a total of 220. White is Neutral and ground is Green or bare copper.
How will a 3 phase panel give you 110 volts and 220 volts?
A three phase panel will not give you 110 and 220 volts. A three phase four wire panel will, but not at these voltages. The nearest voltages will be 120 and 208 volts. The 120 volt is the wye voltage of 208 volts. 208/1.73 = 120 volts. A single phase three wire panel will give you 110 and 220 volts.
How connect a transformer 380 volt 3 pH to 220 volt mono pH?
any one of the three line to neutral is 220 volts
What is voltage between earth and line?
In a typical residential situation there is 220 to 240 volts between the two hot wires that are typically red and black and 110 to 120 volts between neutral and either black or red. The voltage between neutral and earth should be zero.
If a sine wave has a peak value of 220 volts what is the route means square value?
If the Peak to neutral voltage is 220 volts, the root mean square voltage is 155.6 volts (sqrt(220)).
What is the resistance value if you connect the 3 volts led at 220 volts?
Actually, if you connect the above described LED to 220 V, it will immediately burn out then the circuit will be "open" and the resistance will be "infinite".
Is it safe to connect 380 volts 3 phase supply to 220 volts 3 phase supply?
No.
Why does 220 volt line put out 250 volts?
A 220 volt line may put out 250 volts because this specification features voltage that varies between 220 and 250 volts. In other countries, the electricity varies in voltage between 110-120 volts.
How do you hook up a water heater with red black and white wires?
Sounds like it is a 220-240 Volt hot water heater. The black and red are connected to the 220 volts supply and the white is connected to Neutral. At the breaker panel red and black connect to the 2-pole 220 volt breaker and white goes to the neutral bus bar.
How to wire an appliance that has black white red and green wires?
It is most likely that the appliance is 220-240 Volts. Check the rating plate. If so you need to connect to that type of service and to a breaker that will handle the load. The 220-240 Volts is connected between Red and Black, White is neutral and provides 110-120 Volts between it and Red or Black. The Green is the ground.
How is 110 volts and 220 volts measured?
With a voltmeter Keep volt meter terminal on phase and neutral wire and it will show the exact volatage
How do you add a neutral wire for 220 volts?
Standard wiring for 220 volts which is also referred to as 240 volts, commonly has four wires. One is red, one is black, one is white and one is a bare copper wire. The red and black wire carry 120 volts each, the white wire in usually your neutral which hooks up to your ground along with the bare wire.
How do you install a 220 plug?
You need two hot legs of 110 volts to make 220. While each led is 110 volts to neutral, between the two hot legs you have 220v. You should have two different hot legs of 110, a neutral and a ground to meet code now a days.
On a 220 volt circuit where the white wire is common how many volts would the red wire be?
3 OR 4 . you only need 2 wires for 220, 1 phase is 120v between 2 of them its 220v . you also should have a ground for the third wire ,and the newer stuff requires a neutral or white wire for the 4th wire. hope i helped , D
