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.
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 wire is needed for 1600 amp service?
A 1600 amp service typically requires 500 kcmil copper wire or 750 kcmil aluminum wire. It's important to consult with a qualified electrician to determine the exact size and type of wire needed for your specific installation to ensure safety and compliance with local electrical codes.
What size conduit is correct for 10-3 gauge wire?
You can pull 10 #3 gauge wires in a 2 1/2" conduit.
Does a reducing bushing make wire pulling easier?
No, a reducing bushing does not make wire pulling easier. It is used to adapt the size of a conduit opening to accommodate a smaller size conductor or conduit. Proper lubrication, good planning, and the right tools are more effective for making wire pulling easier.
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.

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
What is the ac resistance 500 ft o a 1000kcmil aluminum wire in steel conduit?
The AC resistance of a 1000 kcmil aluminum wire over 500 ft will depend on the resistivity of aluminum, which is approximately 2.82 x 10^-8 ohm*m. The resistance can be calculated using the formula R = Ο * L / A, where Ο is the resistivity, L is the length, and A is the cross-sectional area of the wire. The presence of the steel conduit may affect the overall resistance, but specific information on the conduit material and dimensions would be needed for a more accurate calculation.
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 conduit for 400amps?
The sizing of conduit systems that wire has to be pulled into is dependant on the physical size of the conductor being drawn into the conduit. The second governing factor is the conductor count of the specific conductor that is needed. A 500 MCM copper conductor with an insulation factor of 90 degrees C is rated at 430 amps. This is where the conductor count is need by the service, as to whether the service is single or three phase. In this specific case, the electrical code will allow both single and three phase installations to use the same size conduit. A maximum total of four 500 MCM conductors can be drawn into a 78 mm diameter conduit.
