Small electrical upgrade

Just watched the video & thought I'd clear up something for you. When measuring the voltage on a cord with no load on it, ie. the end has nothing plugged into it, there will be no voltage drop at all, no matter what size. Voltage drop only occurs when there is current present.

You could have a 100' cord that is 22 ga & you will get exactly the same voltage at the far end as you do where it's plugged in. The reason there was a difference in the 2 readings is that the voltage at the source varied a bit.

That's not to say you wasted your time & money though. With a load, the new cord will have much less voltage drop & your table saw will thank you.

Thanks, I was under the impression that the voltage would be less due to more resistance in the smaller cord using ohm's law .... V=IR.
