    GFCI breaker + receptacles?

    Quick question guys. I am not a licensed electrician but I do electrical work on the side, I'm a mechanical engineer by trade. I came across a minor issue on a job I did recently and I'm trying to determine the cause. My question is this: if you have a GFCI breaker installed (15A) is it OK to have GFCI receptacles installed on that circuit or could it potentially cause problems (as in one or the other tripping)? I understand that doing this isn't necessary and is a waste of money, but would it hurt?

    Thanks

    you can connect gfcis in series but it does not add really any additional protection, and they can trip randomly

    What is the minor issue?
    After you learn refrigeration, fixing an A/C is like a walk in a park under shade trees
