In my spare bedroom, there are four electrical outlets. If I use a vacuum cleaner in one of those outlets, the breaker trips. However, if I use any of the other outlets, it works fine. Is the outlet itself bad, or is there some other kind of wiring problem? This breaker only powers the four outlets, a ceiling fan and light. I had the light (7W LED) on, and everything else off or unplugged. All outlets show 120V Hot-Neutral, and 0 V Neutral-Ground. The breaker is a 15A Combination Type AFCI Type BRAF.
On the contrary, that outlet is probably the one that has the most direct connection to the breaker. The additional wire between that outlet and the others is what reduces the current that the vacuum cleaner draws just enough to keep the breaker from tripping.
