what gauge extension cord for power tools
Personally, I recommend going one step down in gauge (thicker inner wires) for electric chainsaws. For example, for a 15 amp electric chainsaw the chart suggests you buy a 14 gauge cord but I recommend a 12 gauge extension cord at 50ft for a 15 amp power tool, and 10 gauge for 100ft cord. To determine what size, or gauge, cord is needed, you will also have to determine the cordâs length.
