The longer the extension cord the more the loss you get. Think of it as water flow.....long skinny river vs. a short wide river.......16 guage vs. 12 guage. You will get a lot less current drop through a short (wide river) 12 guage wire than a long 16 guage. It is optimum to not even use an extension cord if possible but that is not always easy to do. I myself need a 15ft cord and use 12 guage. Hope this helps muddy the river so to speak..

Thanks for your reply!

I understand the water analogy when it comes to electricity. Amperage is flow (GPM) and wire size or guage is the size of the river, pipe or what ever conduit you choose for the analogy. Ohms is it's resistance to flow (TDH) . Voltage is pressure (PSI).

The larger the conduit, the less resistance to flow and the more flow you can get through it with the same pressure.

Since my 50 foot 16/3 cord is rated to carry 13 amps at 125 volts it should carry a mere 5.5 amps with ease! In other words my "river" or "pipe" is plenty big enough to carry the amount of flow required for my Bradley to operate at maximum efficency. My Bradley is only using 42% of this cord's flow carrying capacity!

A 50ft 12/3 cord is rated to carry 15 amps at 125 volts. Only 2 amps more. My Bradly is still only going to draw 5.5 amps MAX unless it malfuntions. So now with the 12/3 cord I am only sing 36.66% of the cords capacity.

So unless my 50ft 16/3 cord is damaged or I have another load on the circut I am plugged into, it should actually be of sufficent capacity to actually run not only ONE but TWO Bradleys at the same time at normal MAX amperage draw.

Am I right or am I wrong? If I am wrong.... how so and what am I not factoring in?
