Generators and backup power

In short

  • Generator outdoors only, at least 6 m (20 ft) from windows, doors and vents, exhaust pointing away from the house. Never in a garage, cellar, shed or barn. A battery-powered CO alarm in the house.
  • Never into a socket. A generator is connected to the house wiring only through a changeover or transfer switch fitted by a qualified electrician.
  • Size it for the essential loads (H61-01) plus starting the biggest motor (pump, fridge: 3–5 times their power).
  • Inverter generator for electronics, boilers and shorter cuts; open-frame or diesel for pumps, tools and long cuts.
  • Petrol (gasoline) without stabiliser lasts roughly 2–3 months; rotate your stock and keep it out of the house.
