This is a red equipment ground beside the red ungrounded conductors and the white ungrounded conductors, the switches supply 240v sportslighter fixtures on the pole. The installation is EMT conduit with 10/2WGUF supplying the switches. I don't use conduit in lieu of a ground but if you only had red on the truck and did not want to get the green wire it might be a good time just this once to use the EMT as a ground.
