How do I calculate what size wire I need?
How do I calculate wire size for motors?
- Multiply the resistivity (Ω•m) of the conductor material by the peak motor current (A), the number 1.25, and the total length of the cable (m).
- Divide the result by the voltage drop from the power source to the motor.
- Multiply by 1,000,000 to get the result in mm2.
What size wire do I need to run 300 feet?
for 300 feet for 100 amp rated service I would use Aluminum direct burial 1/0-1/0-1/0-1/0, the forth can be as low as #4 for the ground (but also in conduit, even if in conduit must still be rated underground wire and required by code also) Also note the size wire the breaker can handle, cannot cut strands to make fit.
What size wire do I need for a 200 amp service 200 feet away?
Wire Sizes For A 200 Amp Service
To safely use a 200 amp electrical service, you will need to use #4/0 Aluminum, Aluminum Clad Wire, or #2/0 Copper. These are the safest wire sizes because they will allow you to use the full amperage of your electrical service without too high of a voltage drop.
