What this works out

The steps

Work through these calculators in order. Each one takes the measurements from the step before.

  1. Maximum demand of the house
  2. Charger load
  3. Cable size
  4. Voltage drop

Questions for your electrician

  • Are the supply fuse and the main cable big enough for the charger as well as the house?
  • Does the network operator need to be told, or to agree, before it's connected?
  • What earthing arrangement will the charger use?
  • Will the charger need load management to share the supply?
