Question

Extension cords. If 14 gauge can supply 15A


Up to 50FT, why does 25FT & 50FT 12 gauge cords exist? I can't think of any reason to ever need 12G cords less then 100FT. All I can guess is that 12G would produce slightly less heat than 14G at the same current draw. Maybe there's more to it other than price. Because I could just buy a 25FT 14G instead of a 12G version and save money for example.

I've been wondering about this since I brought some new cords with locking feature. Locking cords FTW! What have I been doing without them.

Yes they do. You can get them at Farm & Home stores, or make your own.

When using high torque, higher amperage tools like ciruler saw, table saws, hammer drills, planners, ECT. a 12 gauge will have less voltage loss and allow the tool to not loose power and over heat the tool.
Locking connections sounds great if your talking about twist locks, but limits what you can do with the cord, It's only going to with another twist lock.
A simple over hand knots worked for me for 40 years.

#1 reason: The PITA factor of wrestling with long cords.
#2 reason: Most need for power will be closer than 100 ft
#3 reason: Two 50ft cords can be joined together easily.

The 12 gauge cord will handle more current than the 14 gauge even though the "rating" is the same. My compressor and shop light would not run together at the end of a 14 gauge cord (light would dim and compressor would hum, but not start, when the light was on) but would work at the end of a 12-gauge.

We use 12 ga cords and even 10 ga cords when core drilling and the generator or power source is far away. Voltage drop is a motor killer.

I seem more reason to have every extension cord except for those that are used for interior lighting to be 12gauge and to eliminate the 14 and 16gauge records that are so prevalent. This would do 2 things, it would significantly reduce the price of the 12gauge cords since there would be more of them available and it would help make things using extension cords run better despite the user's best efforts.

12 and 10 ga. cords use 15 amp plugs and sockets (straight blade configurations).

So there's still voltage drop on the 14G cords. Good to know. Thanks for the explanations everyone.

@joecaption I brought these 50FT 14/3 and 100FT 12/3. So far they seem to be working well. You hold the button as you plug in something until you hear/feel the click. I thought they were a good idea after the female end of my old cord stopped holding plugs tight. Tying them didn't help as any vibrations caused the plugs to work loose. I could've just replaced the end, but the entire cord was getting pretty worn out anyway.

The red one was to replace another cord that was cut in half. I actually put that one back together but didn't feel safe using it anymore.
