Hello all, I recently did a home and upon testing the exterior outlet for GFCI protection, the outlet tripped a GFCI located elsewhere in the home. It appears that it took out the garage and bathroom outlets also, not tested prior to exterior test. After a very exhaustive search of the entire home, attic, crawlspace and panel I could not find a GFCI outlet anywhere. (Limited visual access to to the home being occupied.) The homeowners, agents and my clients are not to happy. I wrote it up as it happened but woud like some input on how to handle this type of situation and the correct way to write it up. Thanks for your input!! B. Burns MHHI
