Hi Not an electrician but just want some advice about which electrician seems to make most sense before I go with them. Situation is I would like to have installed a 3 phase ev charger at my business premises. Currently it has a standard domestic single phase supply and a standard simple distribution board. Assuming dno will install a 3 phase supply and I can get my electricity provider to meter/charge or what they need to do... Electrician 1 says we could keep the existing single phase dist panel as is and 'feed it' from one of the phases. Then separately connect the 3 phase ev charger across the 3 phases as necessary. Electrician 2 says that the existing dist panel needs to be removed and a new 3 phase panel added with the various loads 'balanced' across the phases including the 3 phase ev charger . Clearly they have a more technical view of what they intend to do but that is how they explained it to me. Cost differential is material between the two so advice on the most common sense and safe approach would be much appreciated. Note, minimal existing significant loads eg... Kettle Washer dryer Oven/grill Then the usual insignificant loads like fridge/freezer/gas water heater and heating/3 pcs/ 20 led lights/etc... The ev charger is likely to be 11kw or 22kw depending on supply capacity.
