Whenever I plug my vacuum into the downstream outlet the GFCI trips. I suspect the GFCI is at least 15 years old and the vacuum

  • Does anything else trip the circuit when plugged in "downstream"? – mike65535 Apr 30 at 12:28
  • Could simply be that the vacuum is arcing and the GFCI is doing its job. – isherwood Apr 30 at 13:26
  • If you plug the vacuum into a kitchen or bathroom GFCI does it also trip? – Harper Apr 30 at 13:35
  • Motor loads and both GFCI's and arc fault protected circuits don't play well together, brushed motors create arcs, all motors create inductive kickback, these spikes on the line both damage the electronics and or confuse the circuitry so they trip. – Ed Beal Apr 30 at 13:37

GFCI breakers do wear out, but before you go out and buy a new one, do you have any other GFCI circuits in the house that you can try with the vacuum? That would help isolate the issue to the breaker vs. the vacuum itself.
