It just amazes me that no one really knows what a gfci does or how it works.
This is not a slam against you Moon, but to the countless people who comment on ground fault circuit interrupters.

Now getting to your question.

Did you read this in an instruction manual for your microwave?

There should not be a reason why you can't plug a microwave into a gfci protected outlet. A microwave is a very common kitchen appliance. It's not a 'sensitive' peice of equipment. So called leakage current (?) will not trip a gfi.

A gfi trips when there is an unbalanced load on the neutral. A current transformer detects this unbalanced load and opens the circuit. An unbalanced load occurs when current takes a shorter path back to it's supply. To do this it requires a pathway. The grounding conductor is that pathway.

A ground fault occurs when current enters an outlet and leaves on the grounding conductor (ie. dropping a hairdryer into a full sink) rather than on the neutral conductor. The current transformer inside of the gfi detects this by sensing unbalanced current. If 20amps enter, 20amps must leave, and it leaves on the neutral. If 20 amps enter and 18amps leaves on the neutral, and 2 amps leave on the ground, there is an unbalanced load of 2 amps. The gfci trips. All gfci's (sparkys correct if wrong) trip at 5mA or more.

I've been an electrician for over twenty two years. And in that time have never heard that you shouldn't plug a micro into a gfci outlet.
