The voltage at which a Level 2 charger operates is higher than standard household appliances. This always raises the question of permits and if the owner needs one when installing such a device. Although the answer may differ depending on the local regulation, this usually comes down to two separate scenarios. You will not need a permit for an indoor charger that plugs into the wall outlet, assuming there is a 240V outlet in your home. The situation is different with outdoor devices that hardwire into the electrical installation inside your house. This should be done by a professional and may also require a permit of a sort.
