Common mistakes

  1. Wrong RCD/RCBO selection for the charger
  2. Undersized cable for the run length and load
  3. Poor cable protection outdoors (UV/mechanical)
  4. No load assessment (main switch / supply limits)
  5. Bad location choice (water ingress, trip hazards, access)
  6. No commissioning / app setup handover
  7. Missing compliance paperwork

If you’re considering an install, send photos of your switchboard and the proposed charger location — it’s the fastest way to quote accurately.
