1-phase - 3.7 kW
A 1-phase charger works on 230V. This enters your meter cupboard through a single-phase wire. This concerns a 35A or 40A connection in most situations. The maximum load capacity is 7.4 kW. Each meter cupboard has at least a 1-phase connection.
3 phase - 11kW
A 3-phase charger works on 400V (power current). This enters your meter cupboard through three phase wires. This concerns a 3 x 25A connection in most situations. The maximum load capacity is 22 kW. If you have a 1-phase connection and you want this adjusted to a 3-phase connection, then only the network operator is authorised to perform this work in your meter cupboard.
