Stray voltage?

Today I plugged a 6hp shop vac into an outlet in the sun porch. The overhead ceilig fan started to turn. Stopped when I shut the vac off. Do I need to rewire something. The outlet is NOT switched.
 
Yes! My guess is that the box that the outlet is on is also supplying the fan voltage. With a bad wiring arrangement, or a bad neutral connection, the load on the circuit could allow some backfeed into the fan. If the controller on the fan is electronic, it could switch the fan to an on state and it would run. If the switch on the fan is mechanical, it might have been the air from the discharge blowing the fan!! (my guesses) Jim
 
Before rewiring, I would check if the exhaust air from the vacuum could have been blowing enough air to spin the ceiling fan blades. The exhaust can bounce off the floor and walls sometimes. I have one shop vac with a removable motor that doubles as a portable blower. It will blow 1/2 inch rocks around on the driveway.

You might test this idea by plugging the vacuum into the same outlet, but with the vacuum ouside the porch, and again with the vacuum in the porch, but plugged into another circuit. You may need an extension cord to test this.
 
We have several winners. It was the top mounted vertical exhaust. LOTS of air coming out of there.
Now tell me why the outlet mounted doorbell rings when I use the hand electric beater in a nearby outlet.
 
The could be answer is that a Universal motor in a mixer has radical sparking at the brushes. this causes noise in the 115 circuit. If the door bell is electronically activated, it will trigger. If it its a wired door bell, you must be hitting the chimes with batter. Jim
