Extension Cord Useage - Guage
Sometimes at home we need to connect to an extension cord - camper cord not long enough. What size guage should we be using? Does it matter ? Thank you

There are plenty of online wire gauge calculators. Most allow you to select the amount of voltage drop and to specify the length of wire and the maximum amperage you need.
I carry 2 extension cords, 25' and 100'. Both are 3 wire, 10 gauge. That is about the maximum you can get and they are already plenty bulky and heavy. The 25' extension allows me to pull a full 30 amps so I can run the A/C and something like the microwave at the same time. For the 100' extension the maximum draw is about 20 amps so I can only run one major appliance such as the A/C.
