Anyone ever have a GFCI circuit register normal, then when tripped with a testing device, register reverse polarity?
I had it happen to me today. All of the GFCI’s (exterior, garage, bathrooms) were tied to a single GFCI in the Hall Bath, which is normal. When I intentially tripped the exterior GFCI, it went directly to registering reversed.
All of the GFCI’s on that circuit registered reversed (garage and master bath). When I get up to the Hall Bath, I reset the tripped GFCI, then test it again. It registered “all green.” But, once I tripped it, it went back to reversed.
Never had a GFCI do that.
