First of I'm going to say I'm going to be starting my apprenticeship next week but as I finish getting my last apartment ready as an apartment maintenance tech i notice something different with the outlets. I was wondering if this was safe or common practice? It seems that they ran one leg of the common wire to the body of the outlet so that when i plug in a tester it seems fine (just basic 3 light outlet tester for verifying correct wiring). As i think about this I realize that there are almost 200 apartments that I would bet are wired the exact same way.They took the old two wire -ground and made it appear to be 2 wire with ground. Just thought I would ask.
