I recently attended an outside party where the caterers were having an electrical problem of some sort and I was asked to look into it. Two large coffee urns were instantly tripping the GFCI receptacles outside and in the garage when they were plugged in. I didn't get to examine them, but both appeared quite new and unaltered (?)
Has anyone seen this happen?
They worked fine when brought inside and plugged into a non-gfci'd outlet. My theorizing that something must be wrong with the coffee urns did not go over so well with the catering people.
