I have results from my circuit tester that have clearly confused me, and wanted to know if anyone has experienced this before, and more importantly what it might indicate.
Using a basic GB circuit tester at a home yesterday, I found three outlets that illuminate all three of the testers lights. I have seen this a couple times before, but just noted the unusual reading and told the buyers to have an electrician review the condition.
It has been very rare though (about 3 houses in 2,350)…
Any one know what this could indicate?
