      Good morning, just took delivery on a '22 T8. I already had a NEMA 14-30R in the garage for previous use with a Clipper Creek LCS 25 for a Chevy Volt. Looking on how to use the provided dual charger for this plug.
      
      Option 1: would an adapter like this work AC WORKS 10/3 STW 1 ft. 14-30P 30 Amp 4-Prong Dryer Plug to 6-15/20R 20 Amp 250-Volt T Blade Connector-S1430620-012 - The Home Depot although the charger manual says to reduce risk of fire, use a circuit with 20a (5-15 or 6-20) or 50a (14-50) and nothing about 14-30
      
      Option 2: swap out the 14-30 with a 14-50 and then get a 14-50p to 6-20r adapter since one isnt provided?
      
      Thanks!

      That adapter will work fine. I'm using a similar type of adapter for use with the TurboCord's 220v adapter that came with ours. Mine's a 14-50 to 6-20. I typically charge our T8 to rapid charge it 2x a day in our barn on 220v and then one more time for overnight charging on 110v at our carport attached to the house.
      
      

      
      
      We also have a ChargePoint with a 6-50 plug for our other home that I've been contemplating bringing over to use with a 14-50 to 6-50 adapter to use that same outlet in the barn. Only I'd prefer to buy another ChargePoint but they don't support 2 home units on the same account. They're going to need to at some point! Until then I move the TurboCord from barn to carport and back depending on how quickly I need to juice up (fast during the day and slow overnight).
      
      Anyway, the manual's guidance is based on the fact that your cord likely taps out at 16A. The onboard charger on a Recharge/T8 is rated at 3.4kWh and it won't draw more than 16A on 220v either. Thus the 20A where as your 14-30 outlet has a 30A max that's just a hair under 2x what you'll need. If you want to be extra safe, you could just replace the 30A breaker for your outlet with a 220v 20A breaker. It's pretty easy to swap out. You just need to remember not to plug your clothes dryer or an oven into it. I'd say it's really more of an issue if you were under-rated but as is you're not likely to cause a fire by being over-rated by +14A over what your max draw will be.
