The clueless questions and replies are funny, but also a bit scary. "Provide the exact same power". Yes, but the device will draw more current.

The extension cable offers some resistance to the flow of electricity. That resistance means there will be a certain voltage drop across the line. To compensate for the voltage drop the device will draw more current. Example:

Plugged directly into wall (1,200W toaster):
120V x 10A = 1,200W

Now let's say there is a 1.5% voltage drop across 50' of 12AWG extension cord. That means that instead of 120V you'll be getting 118.2V. In order to provide the same Watts with lower Volts the toaster will need to draw more Amps.

Plugged in to 50' extension cord:
118.2V x 10.15A = ~1,200W


So in this specific example, the toaster will draw an extra 0.15A to compensate for the voltage drop along the 50' of extension cord.

So yes, 2x50' will provide the same "power"... but your appliance/device will draw slightly more current due to the voltage drop. And this is why you want to have an extension cord with a heavier (e.g. 12 gauge) when running a toaster, microwave, snow blower, or anything that draws a lot of current on the other end of it.



The difference becomes more pronounced when you're drawing more current. For example I have a 15A snow blower. Let's assume it's drawing 15A constantly. Over 100' of 12AWG extension cord the voltage drop is around 4%... Not too bad. IF I used a shitty 16AWG extension cord then the voltage drop would be 10%, which is huge! And my snowblower would be drawing 16.3A instead of 15A to output the same 1,800W of power. Using the proper extension cord is critical when you're drawing large amperages.

Here is a handy Voltage Drop Calculator. http://www.calculator.net/voltage...lator.html

I've cannibalized a few extension cords in the past few years. The cheaper ones seem to be using a brass-like wiring. It's not proper brass- it's more like copper that's been cut with a bit of zinc to cheapen it.

Amazon is matching the 100ft for $49.97 that is also at Home Depot. Picked up one of those to use with my tiller as well. Thanks for the post!

i also bought the tiller

I have a 50ft 14ga.

I wonder if I can mix it with 50ft 12ga to get 13ga average over 100ft without burning up the tiller.

Doesn't work like that, the higher gauge cable will still be the weakest link.

does 2x50' daisy chain provide the exact same power as 1x100' extension cord?

It would. It's the same as connecting two hoses together. Same rate of flow regardless if it has an inter connector or not.
