Generator connections

Generators must be connected so they cannot backfeed the mains; a qualified electrician plans the method.

What this covers

Changeover arrangements and inlets for portable generators where appropriate.

Do this first

  • Keep clear of sparking fittings, burning smells or flood water near electrics.
  • Do not keep resetting a breaker or RCD that trips immediately.
  • Note which rooms lost power and photograph the consumer unit if it is safe.

No power, a hot consumer unit or a new circuit? Tell us what is happening. Request an electrician
