Electric Chain Saws
Neil Soderstrom
There are many reasons to buy an electric chain saw: They emit no
exhaust, they are almost maintenance-free, they weigh less and they
always start with just a flick of a switch. Unfortunately, one of
the drawbacks is their electric cord. In addition to lugging the
cord around, cord pliability is dramatically reduced in
temperatures below 40 degrees.
It's also important to use the correct gauge of cord because
maximum cord length is dictated by a saw's amperage rating. Most
outdoor circuits are 15-amp, and cords lose amperage the longer
they run from the source. Under load, saw motors overheat unless
the cord is of sufficient gauge and shortness to maintain
sufficient amperage. Saws rate in the 7- to 12-amp range can work
at distances up to 150 feet, with a specified cord. But some saws
rated 15 amps or higher need a gauge of 12 for just 50 feet.
Double check that the length and gauge of your cord meets your
saw's requirements. Outdoor-rated cords are round-jacketed and
stamped with a suffix of 'W' or 'W-A,' for Wet or Wet-Applications,
as in SJTW or SJTW-A.
