You electricians know this already… so this is for people like me who don't know an electron from an ion.
Last night, for the first time in my new shop, I attempted to use my jointer. I was feeding a 24" long piece of white oak in, and it made a horrible noise and just battered the hell out of my board. I turned off the power and watched the blade spin down… thinking one of my cutters must have been damaged in the move to my new quarters. It was then that I noticed the darn thing was running BACKWARDS! A quick check of "3-phase motor running backwards" on bing told me that the electricians had not done their homework when installing the plug. Bottom line, you can switch one wire and reverse a 3-phase motor. Easy fix, but wow I wish I had checked that first! Who would have thunk it?
