Power planning

  • Extension cords rated for outdoor
  • GFCI protected outlets
  • Don't overload circuits

Common mistakes

  • No timer (lights on at noon)

Practical

  • Inside-only lights outside (waterproofing)
  • Forgetting to test before hanging

Timing

When to install

  • Day after Thanksgiving traditional
