Hola everyone,
Just a basic 'safety' question. I just watched a video on YouTube where a gentleman used a 600w standard dimmer switch as a "Variable Current Limiter" motor control. I was wondering:
A) How safe is this?
B) To determine power tools/motor sizes that are ok to do this, just use Ohm's law to figure the watts & keep it under the dimmer switches wattage rating?
EG: if I have a bench Grinder that is 300watts, would it work to use a 600watt dimmer?
C) If this isn't a wise thing to do, what would you guys recommend as a quick-n-easy speed controller for things like bench grinders, drill press, etc?
Thanks for any input,
Rod
