500mcm 37 strand copper wire = 1.544lbs/ft.
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.
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.
Use AWG # 4 copper and you will have a 2.6% voltage drop which is acceptible.
A 500 MCM wire with an insulation factor of 90 degrees C is rated at 430. Most 400 amp services will use parallel wires on each leg to feed the circuit. A 3/0 wire with an insulation factor of 75 and 90 degrees C is rated at 200 and 225 amps respectively. The insulation rating of these conductors will be 600 volts.
The ampacity of 350 MCM (thousand circular mils) copper wire can vary based on factors such as insulation type, installation conditions, and ambient temperature. Generally, under typical conditions, 350 MCM copper wire can handle approximately 400-500 amps. For precise applications, it's important to consult the National Electrical Code (NEC) or an ampacity chart specific to the installation conditions.
400 MCM (thousand circular mils) copper wire weighs approximately 1.51 pounds per foot.
Its weight is(432) x (the weight of each cubic foot) .
No it is a conductor. Aluminium wire is used in 400 amp services to keep the cost down over copper wire.
It depends on the length of the run

Assuming you are working with 240v, you need 4/0 copper conductors.
Use AWG # 4 copper and you will have a 2.6% voltage drop which is acceptible.
The conductance of a wire is the reciprocal of its resistance. Therefore, for a wire with a resistance of 400 ohms, the conductance would be 1/400 siemens, or 0.0025 siemens.
The weight of 400 grams of water is 400 grams because the weight of water is equivalent to its mass.
