Just got a one year old Laguna 16hd with 4.5 hp phase 1 motor and it was setup with a 4 wire plug and my garage has a 30 amp 3 wire plug. The connection box on the Laguna as it is currently wired from left to right has a black wire, red wire, open slot, white wire and a ground. My new 3 wire electrical cable has a black, white and green wire. If I match up the black to black, skip the red since this is a 3 wire and it is not in the cable, white to white and green to ground will this work. I don't know that much about electicity but thought I would see if anyone has some basic knowledge about this type of wiring. I can always get an electrician but thought if this is a simple question with a simple answer, I would try here first. Any help would be appreciated. Thanks!
