I have a 500 hp generator that I have never actually used. The
directions say use a 12 gauge cord with it ... I bought 14 gauge
cords. Are these too strong?

Next question. Our weed eater stopped working -- my son was using one
of the 14 gauge cords with it when it started smoking and the
connection on one side is black. Is it because the cord was too
strong? Or do I need to replace the weed eater. It's fairly old.

My son and I have recently taken over the outside chores -- and we are
having to learn as we go. My husband used to do all this but his
health is bad and he can't help. Appreciate any advice.
