- When you are running near max capacity, then voltage drop becomes a large
- issue. This is the case when you are running a 2 HP motor on a 15 or 20
- amp circuit.

- I think 10 ga wire would be overdoing it, but 12 ga would certainly be a
- good idea, even for a short 25 ft run.

- I am slowly replacing all my extension cords with ones containing 12 g
- conductors. I am tired of having compressors that will not start because
- the voltage drop is too high.
