I am doing quite a bit of work using my compound miter saw (15 amp), circular saw, and scroll saw. I have each plugged into a 6-outlet surge protector power strip 14 gauge with 6' cable. Only one saw is turned on at a time.

I have to use an extension cord. Which should I use and why? Does one have more resistance or not matter?

14 gauge 15' extension cord
12 gauge 25' extension cord

 

Door number 2. It will handle the start amperage as well without problems. One thing never to use an extension cord on is a compressor.

 

Start up amps? But both cord are rated 15A so why is the longer 12 gauge cord better? Does it have more or less resistance? Any more opinions and facts? Help a novice out.

 

Motors draw more current on startup than the running loads.

 

Not sure why you have to have so many opinions. Facts are the larger cord will service you better. I do construction for a living and know my equipment well. I know what cords to use for which piece of equipment. Those are the facts. Run with it or lateral off.

 

Larger conductos means less voltage drop. Less voltage drop means there is more power available. This is important when starting large loads.

 

I went ahead and did a voltage drop calculation:

Also, Plug strips are not permitted to be daisy-chained or plugged into extension cords. Extension cords and plug strips are for temporary (90days max) installation and use only.
