Have got the Wallbox installed with 3 phase supply, but from my own installer. The one Rever has send first arrived with cheap chinese Breakers and Cables and additional costs of 8.000 THB, so I have send them home. Then they came up with a new quote of 15.000 THB to install Schneider Breaker ,RCCB and Yazaki Cable. I just waved good bye, bought all by myself for 8k THB and got it installed.
