I have a Gen 1 HPWC on a 100 amp circuit. I can charge Model S P85D with dual chargers at 80 amps and Model 3 at 48 amps. However, I get the red ring and it won’t charge 2021 Model X LR. Reviewing previous threads, it appears this is a known issue and solution is to change dip switches in HPWC to lower amperage to make it work.

My question is, in order to charge Model 3 and Model X at 48 amps, what breaker amp should dip switches be set? (Relevant options are 40A, 50, 60, or 70A breaker)

Thanks
