I am refurbishing an old Craftsman 10" table saw that has been collecting dust in the back of my shop for years.
I don't remember exactly how I acquired it, but to my recollection the one time I tried to start it sparks flew from the on/off switch. The switch controls an integrated 110vt receptacle which the motor plugs into. All is factory original.
I tested the motor by plugging the motor power cord directly into a wall receptacle and it runs fine. I would like to resume using the factory On/Off switch (because it is a safety switch- pull On, push Off) but wanted to check it first.
Opening the switch box I discover that the switch is double-pole, i.e. opens and closes both the hot and neutral wires that lead to the motor receptacle.
- why did the manufacturer install a switch that opens/closes both the neutral and hot?
- can I safely use the switch to only open/close the hot (the neutral side is dead/open)? I can wire the neutral to bypass the switch...
