initial install date was brought forward as a slot was available. I got the free issue cable installed within the ceiling void and then arranged for the install. First installer found that the garage fuse baord that the EV charger was to be wired to only had one spare way in the board....photos and description that i sent clearly indicated that it only had one spare way? install stopped until i got a new larger board installed with the required minimum 2 spare ways for the double pole switch. rearranged install and electrician came and wired up EV charger. Electrical tests completed and all ok. First time charge a couple of days later caused the MCB to trip in the main house board? The EV charger has not been down rated to 3.7kW as requested (main cable to garage needs upgrading to 6mm to give full 7kW charge) Have now had to request the unit be downgraded to the requested 3.7kW before i can use it....very frustrating. Older model units could easily be set to the 3.7kW by dip switches but newer units seem to have none? hope can be set to 3.7kW over the internet connection? have emailed service but not yet got a reply? I believe i did ask for a tethered unit but the electrician only had an untethered unit down on his work sheet? settled for that just to get it installed on the day......
