Clock going cook coo
 
I have a small alarm clock plugged into a receptacle in the bathroom. When my wife runs her breast pump on the same circuit (one receptacle up or down range) the clock starts acting crazy. It will gain and loose a minute in sync with the cycles of the breast pump. I checked for voltage drop, but it didn't appear to be any. However, I noticed that the voltage did seem to change at a faster rate in sync with the breast pump as opposed to a slow gradual increase/decrease of about +- 1 volt without the pump.

Congrats!

My only guess is that your clock is very very sensitive to voltage/current changes, or harmonic distortion ( I don't think a breast pump would really do that.)

Or just a simple loose connection...try just running one heavy load on the circuit and measure voltage.

Heavy load? Like a vaccum? I have a 12 amp vaccum, should I not see any voltage drop?

Yes, not a big drop, 2-4 volts can be normal.
