    Planning circuit in a business to a proposed single charging spot. Have heard that a 32A circuit is the highest potential single phase requirement.
    Any advice please?

    Generally that is correct for single phase.

    There are a few exceptions but I don’t think you’d need to worry about them.

    Note: The car will pull the full 32A for hours. So you need to spec above that. 40A RCBO is usually what gets installed.

    If you want load sensing you may also need data cabling between charger and fuseboard. Only required if you may be nearing the load limit of the business.

    The thing is planning for the future. If you have nerd for one charger now, you may well find you need two or three within a few years as the EV market share doubles from its very low base.
