extension cord length

[scarecrow56]

I'm gonna put my TT in the back yard. I have used a 50' extension cord to power the slides and fridge and a few other things including the AC for a short time. Question is, This time I'm gonna have to use a 100' cord. How will this affect the voltage/drain on the power, if at all?

If at all? :h Obviously the greater the current draw the greater will be the voltage drop. You also haven't mentioned the gauge of cable you plan to use - again obviously, the lighter the gauge the greater will be the voltage drop. You haven't provided any of this information, including the unloaded source voltage, so no one here can tell you what voltage drop you can expect. Measure your unloaded source voltage and plug numbers into this voltage drop calculator.

Yup length AND wire gauge as well as load will determine whether your voltage drop is acceptable or "will let the smoke out" of you 120 VAC appliances.

If all you are running is a battery charger, smaller gauge can be used. If you plan to run high amp items like a roof air, a VERY different matter.

What size wire will the extension cord use? Is your TT 30 amp or 50 amp...
