What size conduit for 3 500 mcm wires?
The required size of a conduit raceway for a 3-5000 mcm wire is 300 kcmil. It maximizes the limits on the wire fill for raceways.
What size aluminum wire on 225 amp?
300 kcmil @ 75°
What size conduit is correct for 10-3 gauge wire?
You can pull 10 #3 gauge wires in a 2 1/2" conduit.
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 size wire for 400 amp distribution panel?
For a distribution panel rated at 400 amps parallel runs of 3/0 conductors will do the job.

When do you derate wires in conduit I know the code says more than 3 current carrying conductors but is there a length of conduit run when you should start to derate?
There are two things here to keep in mind. If you are trying to add more conductors to an existing conduit run use the cross sectional area of the conduit to see if more wires can be fitted. The second thing that's relates to length is the voltage drop at the load. To size the conduit work backwards from the load amperage to size the wires. If a long distance is involved a voltage drop calculation will be needed. Then select the conduit size to accommodate the wires recommended for that load amperage. The length of conduit run is not brought into the equation on de rating wire size it is always about keeping the voltage up at the load end of the run by increasing the wire size and selecting the proper conduit size for that wire.
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 size of copper wire can carry 30 amps?
Couple of things wrong here. 30 isn't a wire size. If you mean a wire that can carry 30 amps that would be # 10. Now it depends on how many # 10 wires you want to put into a conduit that governs the size of the conduit.

What size conduit do you need to install a 0000 wire?
4/0 gauge wire, depending on its insulation type is rated from 230-260 amps. Assuming you are running a new power supply with the 4/0 wire, you will have a minimum or three 4/0 conductors and a ground wire for a single phase power supply and four conductors with ground for a three phase power supply. Three 4/0 wires require a minimum 2 inch conduit. Four 4/0 wires require a minimum 2 and 1/2 inch conduit. These conduit sizes I'm quoting come directly from the NEC, the National Electric Code. These sizes of conduit are determined by the basic rule that all the conductors in a conduit are not to exceed 40% of the volume of the pipe. The other 60% of air space is required for heat dissipation.

How many 10 stranded conductors can you pull in a 1 inch conduit?
Need to know the wire # size to compute wire fill in conduits
Is it permitted to use flexible conduit over 6 feet in length as a grounding means?
No. The new electrical code change does not allow any flexible conduit to be used as a ground means. It is now required to have a green ground wire pulled into the conduit with the other conductors in the flexible conduit. This grounded bonding conductor is not counted as wire fill when calculating the size of the flexible conduit to use
What size cable to use for a 3000 watt load?
At a minimum you would need to run 5 parallel sets of 1000 Kcmil/mcm 90c rated copper wire. This is not calculating for other factors such as ambient temp., volt drop, or conduit fill.
