My parents just bought a house that is still under the original warranty. There is a standard GFCI outlet in one of the bathrooms with outlets in the other two bathrooms connected to the load side of that GFCI. So far so good.
On their back porch they have another GFCI outlet. It is also connected to the load side of the bathroom GFCI. They found this out when some contractors were working and managed to trip the GFCI in the bathroom with equipment plugged in to the GFCI on the porch.
They know the builder as he just completed other work for them. I contend that it's wired incorrectly and should be fixed under warranty. He admits that it seems odd but doesn't want to get it fixed, of course.
They just had other electricians doing work at the house last week who looked at it and said "that's strange, but it's not dangerous". I'm not saying it's dangerous, just wrong.
I would like the builder to fix it, preferably by putting the outside outlets on a separate circuit. Thoughts?
