Hi, I'm thinking of running a NEMA 14-50 outlet to my electrical panel. I know the nema 14-50 has 4 wires. From the look of my electrical panel, i'm a bit confused as of where I should connect the neutral and ground wire to. Can I connect both wires to the same bus bar as where the green wire of my AC unit is connected to? See the picture below. Thank you for your help! Would using a 6-50 outlet a better alternative since that only needs 3 wires? Note. I know my main load can only take 100 amps. We currently have the AC unit breaker at 50 amps but since we don't use the AC at home and I will rarely come home to use the charger (i.e. I work far away). I plan to add an additional 50 amps breaker to the existing panel for now until I get a chance to upgrade my electrical panel in the future. I will be charging my car mainly at my 2nd house near work.
