The cable calculation procedure for an EV (Electric vehicle) charger

A basic cable calculation guide, and some comments on installing an EV charge point. Installing an EV charge point is not that straight forward, and new issues are coming to light all the time. Guidance is constantly changing, so I think it's important to keep up to date with the changes, and if possible go on a recognised course provided by a reputable trainer. Such as the 2921-31 for domestic or for more complex installs 2921-32 or the 2921-33.
