Question:
Do EV charge points need to be on dedicated circuits?
Answer:
Dan Jackson FIET,
Yes. 722.311 states that a dedicated final circuit shall be provided for the connection to electric vehicles. It shall be considered that in normal use each single charging point is used at its rated current. Where the final circuit supplies more than one charging point no diversity shall be allowed.
Diversity may be allowed for a dedicated distribution circuit supplying multiple electric vehicle charging points if load control is available.
EV charge points require particular RCD protection and earthing arrangements that may differ to general use socket outlets and circuits. When charging, Electric Vehicles often use full load hence the need for dedicated circuits.
