I just bought a new electric snow blower and need to buy an outdoor extension cord. The snow blower says it has a 13-amp motor and I will probably need an outdoor cord that is about 100 feet. I'm confused on the type that is best for this motor as I see some listed with a gauge number and some with an amp number. Do I have to buy one that says it is for 13 amp only or does that make a difference for this motor? Also for the gauge number, I see numbers from 16 down to 10 gauge. What should I buy? I don't want to get the wrong one and burn up the motor on the first try. I saw one review that someone wrote on this snow blower and he said he had a 12 gauge cord and bought a 10 gauge instead and got a little more power from the lower number. Then I read another review and it said that if you are buying 25, 50 or 100 feet to use a 16 gauge. I thought the hardest part was over when I finally picked the snow blower that is best for me to handle and now it is more confusing to pick out an extension cord. Any help on clearing the confusion would be greatly appreciated.
