This is the situation. Customer bought exterior sidewalk heating mats. The mats come with a weatherproof GFI built right in to the male cord end. The outside receptacle that they want to plug in to is also a GFI . Can a GFI be fed by a GFI without causing any undesirable effects and nuisance tripping?
