Installed the home wall charger on a 60 amp circuit with 444/6 wire for a 45 foot run. 60 amp only calls for 6 gauge I went a size up do to local availability and the ability to run 80amp down the road if we desired. The neutral is properly grounded and capped off as its not used.
Install was a breeze minus maneuvering that wire, hooked it up the loaner tesla model s and it read the 48 amp setting and 239 volts charging roughly 34 miles. I had a loaner temporarily waiting for our order 2014 model s.
So here's the issue, Just brought home the new model 3 today (a day later) and its reading 234 volts and 48 amps. So that puzzles me. I broke down the charger to double check the connections and rechecked the breaker at the panel. All looked well.
Any thoughts on why there such a difference and is that of concern? Im assuming 234 is fine as the amperage is fine but I'm not a full time electrician, a very good and safe handyman but that's above my pay. By the gauge and length wire I ran it should only have a.5 volt drop over the run. I am confident the wiring and breaker is solid. I am using the top entry wall mount box. I am not sure if it is the tesla just reading different being new or if there is something up. The model 3 charge at about 42 miles per hour on that 234 48amp reading.
Any ideas on the change in voltage??
