Good point about the breaker protecting the wiring not the equipment. I put in a 30 amp 240 volt double pole breaker and a 50 amp receptacle to match the plug on the welder. I will mark the receptacle '30 amps max' and will replace it with a 30 amp receptacle if/when I ever move. I also made an extension cord using # 10 wire and ends the same as those GUS68 used. The plugs and receptacles are all 50 amp but only have # 10 wire, when I no longer need the 50 amp ends to match the welder I will remove them. The transfer switch came into use the last few days, it's amazing how a mere 18 inches of snow will cause a four day power outage, but there were 20 or so trees over on the power lines this weekend. Took out a lot of wire and broke off a few poles. Got a few hours overtime on the snowplow though.
