Can ZEB draw electricity at the same time as my EV charger?
A ZEB and typical EV charger together draw safely under the standard household supply*
Yes, a typical EV charger will draw around 30A and the ZEB around 40A, giving a combined load of approximately 70A, still below the standard 100A household supply limit*, subject to whatever other appliances are running at the time.
*Some households have lower incoming supply, a qualified electrician is needed to verify your households capability.
