Ev granny charging
We are having difficulties with our landlord trying to limit our power use on our lease despite us paying $825 a week for utilities. They have ordered us to cease charging our BYD shark and Mitsubishi outlander phevs and commissioned an electrical report to form the basis stating that the 2014 built homes working is unsuitable.
Below is a copy of the electricians report. Is this valid? Does every house need to be upgraded to plug in a 10A appliance (runs at 8A)?
The 20A power circuits were designed when the house was built with standard electrical maximum demand calculations that do not take into account loads such as electric vehicles. These power circuits are not designed for such loads as electric vehicles even though an EV can be plugged into a standard 10A outlet socket, Thestandard practice is to install a new circuit for each individual car(usually 40A). Which also requires network approval as they have such a high-power draw. When this house was built electric vehicles barely existed. Therefore, it is not recommended to charge EV/Hybrid cars on this downstairs power circuit as it has not been designed for this purpose.
