Help!!!I am very familiar with installing electrical circuits but this one has me stumped. earlier this year I bought a house that was built in 1977. It has a complete bathroom in the garage. The house had all ungrounded outlets in it. I wanted grounded outlets in the garage, bathroom and outside so I put in a sub panel in the garage. I have been using GFCI outlets exclusively in the garage and outside. I wanted an outlet and a vent fan/light in the bathroom. I thought that a GFCI breaker would be easier to use than a regular breaker and GFCI outlet. I installed the GFCI breaker according to the instructions. I installed the white wire on the load neutral bus like it said. The grounding buss and the load neutral buss are separate. When I energized the circuit everything was fine until I put a load on it. The load was a 75 watt light bulb. Even a "wiggy" type volt meter tripped it, just the GFCI part. My Fluke didn't trip it because it has a smaller load factor. The instructions said that this must be totally separated circuit, which it was. I finally pulled out the GFCI breaker and put in a regular breaker and made the first outlet a GFCI outlet and ran the rest of the circuit through it. I only had two lights and a vent fan on the circuit. After replacing the GFCI beaker with a regular one everything worked like I wanted it to, even ran the shop vaccuum to clean with. I'm wondering if the GFCI breaker would not work because it was in subpanel or was I just not reading the instructions right. I am always learning something from you folks. I always say the day is no good if I haven't learned something. Thanks, Rick
