anybody who is not wiring red+/black- right and white+/green- left is just flat out WRONG!!!! I hate when i go to a job that has been wired in any other method. It makes no sense.
yes... it doesn't make sense to use black as negative for 2 conductor and then switch it to positive just because you have 4 conductors. Always keep black as negative. Green also symbolizes as an earth ground so it would make sense that it is ground. Not sure why anyone would switch that around
