Great explanation. I need some wire to make an extension for a buddy's everlast welders. I want to ensure I get the right kind.

Thank You so much for the information and video

Excellent and clear but...how many amps does my microwave need or use? Where do I find that info in order to get the right extension cord?

[larsdahl]

I'm looking for a cord that has little-to-no "memory", i.e. it straightens out easily after having been coiled up tightly for some period of time. Many power tools have this kind of soft, flexible, rubber-like qualities, but I haven't been able to find it in extension cords. 14-16 gauge would be preferable and a 13 amp rating

Is a 12 gauge cord too big for a 7 amp leaf blower? Too much power?

Can I use American cords with a rating of 125v in a country with standard voltage of 240v for my appliance?

I have a small dewalt jobsite fan, if I use a 25ft extension cord 12/3 rated at 15amp. The cord provides more amp than tool requires. Will it damage my fan?
