I am trying to install a ceiling fan in my daughter's upstairs hallway. There were 2 recessed lights with 3 switches. I wired the lap light to the switches and looked for a new source for the fan motor. I figured I had it made as there is an attic light with a pull string nearby. I wired the fan to that light fixture. As it ends up, the light is being fed by ground fault circuit break. The ground fault circuit breaker apparently doesn't like to share the low voltage lead (white). The circuit breaker immediately trips. Any ideas before I take up the insulation in the attic looking for a non ground fault circuit? Is it possible that the ground fault just doesn't like the motor? I could wire the fan and light kit from the attic light (the ground fault circuit)
