I want to install a dedicated circuit for a Miller stick welder. The front of the welder says it pulls 47.5 amps, and I've been recommended to use a 60amp breaker at my main panel. I've read some posts/questions on the net similar to this, and I believe I need to use 6-3 or 8-3 Romex wire. The distance from the main breaker panel to the receptacle will be about 80-100 feet, and the welder has a 15ft cable to plug into the receptacle. All I really plan to weld is 1" and 2" square tubing and angle iron...nothing too heavy duty.
If it is safe (and does not violate NEC), I will run the wiring from the main panel into the attic and bracket it to the roof truss to run across the attic. What I would like to know also is if it is safe/legal to drop the 8-3 or 6-3 Romex through the eve of my house and run it along the ceiling of my back porch into my garage. My eves, porch ceiling, and garage wall are made of cedar. Will there be a problem dropping running the cable this way, or should I drop it down the side of the house (made of brick) and run it underground to the garage?
This job does not seem hard to do, but I want to do it right and more important, SAFE. Any suggestions or recommendations would be greatly appreciated.
