What else can I help you with?
What size underground feeder wire is needed from a 400 amp breaker to a 125 amp panel box. The total distance is 100 feet?
1/0 <<>> This is a voltage drop question. A voltage and whether it is a single or three phase system must be provided to give an answer.
What wire size for 400 amp service neutral size?
You need to look at the regulations that apply in your country. If in doubt, use a neutral wire of the same size as the live wire or wires.
Can you run 500mcm to feed 480 volt 400 amp service?
500 mcm (or 500kcmil) conductors are used for 400 amp 480v single phase or 3 phase systems. The wire AND THE TERMINALS must be rated for 90o Celsius.
What type of panel should be used in 3 phase 400 amp?
The type would be a three phase panelboard. If you are carrying the wye neutral into the service, then it would be a three phase four wire distribution panelboard. Regardless of the style used, it would have to have a minimum 400 amp bus.
What size wire do you need to run for 30 amp service to travel trailer 400 feet single phase 110 volt?
Presuming that you would like the least expensive installation, the following is calculated on overhead aluminum wire. The wire size needed to hold the voltage drop to 3% would be 3/0 MCM. If the installation could be run on 240 volts then the wire size can be reduced to #2.

1/0 <<>> This is a voltage drop question. A voltage and whether it is a single or three phase system must be provided to give an answer.
What information can I find in the 400 amp wire size chart?
In a 400 amp wire size chart, you can find information about the appropriate wire size to use for a 400 amp electrical circuit. This includes details such as the gauge of the wire, the maximum current capacity it can handle, and the type of insulation required for safety and efficiency.
How do you obtain a 230 volts single phase supply from a 400 volts three phase four wire supply?
400 volt three phase on a grounded system is 230 volt single phase, with each phase 120 degrees apart. So, if you have a 400 volt, three phase four wire service (grounded service), you can pull one phase off and reference to the neutral for 230 volt service. Note this may not allow 115 volt service, unless there is also a center tap for each phase.
What information can I find in the 400 amp service wire size chart?
In a 400 amp service wire size chart, you can find information on the recommended wire sizes for conducting electricity in a system with a 400 amp capacity. This chart will provide details on the appropriate wire gauge, material, and insulation type needed to safely and efficiently handle the electrical load in a 400 amp service setup.
What wire size for 400 amp service neutral size?
You need to look at the regulations that apply in your country. If in doubt, use a neutral wire of the same size as the live wire or wires.
Why is 230 volts classed as single phase?
In Europe and other places the standard single-phase supply for houses and small businesses is 230 v which is derived from a 400 v 3-phase 4-wire supply by connecting each customer's circuit between one phase line and the neutral wire.
Can you run 500mcm to feed 480 volt 400 amp service?
500 mcm (or 500kcmil) conductors are used for 400 amp 480v single phase or 3 phase systems. The wire AND THE TERMINALS must be rated for 90o Celsius.
What type of panel should be used in 3 phase 400 amp?
The type would be a three phase panelboard. If you are carrying the wye neutral into the service, then it would be a three phase four wire distribution panelboard. Regardless of the style used, it would have to have a minimum 400 amp bus.
What size wire do you need to run for 30 amp service to travel trailer 400 feet single phase 110 volt?
Presuming that you would like the least expensive installation, the following is calculated on overhead aluminum wire. The wire size needed to hold the voltage drop to 3% would be 3/0 MCM. If the installation could be run on 240 volts then the wire size can be reduced to #2.
How do you connect 400 volts in Singapore?
Singapore uses a 400/230-V three-phase, four-wire, system. 400 V is achieved by connecting a load between any two line conductors.
What size wire needed for 200 amp service 400 feet away direct buried single phase 240 volt 3 wire?
Assuming you are working with 240v, you need 4/0 copper conductors.
How much voltage in three phase line in electric in India. each phase rating 230V?
If the phase voltage is 230 V, then (providing you are describing a three-phase, four-wire, system), then the line voltage will be 1.732 larger -i.e. 400 V.
