Had an electrician complete a 14-50 outlet in my garage utilizing a 50 amp GFCI breaker. After plugging the mobile connector I would get an error of “inadequate outlet grounding.” The electrician verified the all the connections, tested and everything checks out.
Past week, I troubleshooted still with no success.
- swapped with another 14-50 receptacle
- tried 50 amp breaker, non GFCI
- got a new mobile connector + 14-50 adapter (free from tesla, under warranty)
I looked at some YouTube videos trying to compare and see what is different. The one difference I see is that the copper wire was installed is stranded. Does a stranded copper wire matter? I noticed the electrician pig tailed a stranded copper wire to a solid one which is routed to the breaker box where it’s grounded. Is it possible the pig tail of stranded and solid copper be the problem? I checked the pig tail of it and it looks solid. Any insights and suggestions helps. Thank you in advance!
