What gauge wire to use for direct burial for a garage that is 400 feet from your house?
Depends on the size of the sub-panel in that garage. If you are installing a 60 amp sub-panel 400 feet away from the main service panel then use AWG # 4.
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 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.
What size wire to run 400 ft from main panel need 60 amps?
Use AWG # 4 copper and you will have a 2.6% voltage drop which is acceptible.
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 size service conductors do you need for a single phase 600 amp commercial panel?
The size of wire for service entrance conductors for a 400 amp 3 phase service could be 500 MCM copper. This is very large size wire and difficult to bend and shape, to connect to terminals in the main disconnect and distribution panel. This problem is solved by using parallel conductors or on higher ampacities triple conductors. Using parallel conductors the wire size would be three ought (3/0) copper.
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 wire size to use from breaker box to earth ground rod?
The wire size used in a service entrance distribution panel is governed by the size of the services over current device. The larger the service, the larger the fault current could be, the larger the ground wire to carry the fault current to ground. If the largest service conductor carries 100 amps use a #8, 200 amps - #6, 400 amps - #3, 600 amps - #1, 800 amps - 1/0 and over 800 amps - 2/0 for the ground wire. <<>> Golden Valley Electric Assoc. in Alaska requires #4AWG copper wire for a ground from the breaker box to earth ground rod. The same goes from the service entrance panel on the pole.
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.

What is the wire size needed to feed a 400 amp service with parallel copper?
It depends on the length of the run

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 size conduit and aluminum wire for a 400 foot run on a 120 240 volt system?
The key parameter in sizing wire is the current requirement. Once you know that you can look up value in a wire gauge table. The length of the run is important for longer runs because of the resistance of the wire itself. Aluminum wire requires a larger diameter than copper for the same current. Once you calculate the wire size you can then size the conduit.
What has a maximum speed of 400 Mbps?
A Fire Wire 400 cable.
What size ground wire for a 400 amp panel in Quebec?
This answer is taken from the CEC. Table 17 states minimum size of grounding conductors. For a service conductor drawing 400 amps a #3 copper grounding conductor is needed. Also see rules 10-206, 10-700 and 10-812 if you have access to the code book.
You take an SRS of size n from a population that has mean 80 and standard deviation 20 How big should n be so that the sampling distribution has standard deviation 1?
400
