I have a single, feed cable that comes up behind my counter into a single gang box. This box has an unprotected outlet. This cable is then teed off to the left and right. The left cable feeds a GFCI close to the sink. The right feeds another unprotected outlet. All three are over the counter and, I believe, should be protected. Here's the question: can I replace the center outlet with another GFCI and use it to feed the right outlet? I seem to remember something about not being able to use two GFCI units on a single neutral fed circuit due to differential currents causing one or the other GFCI to trip.
Any thoughts or answers are greatly appreciated!
