Background
So I live in Michigan (which of course affects code) and I have a bunch of two prong outlets in a house that I own. If I want to convert these to be 3 prong outlets is it still up to code to replace them with GFCI's with a label "No Equipment Grounding"? The outlets I am referring to are just in bedrooms so not by a source of water like the bathroom / kitchen.
Will the outlet still pass the outlet checker tool?
I know the tool is checking for a ground and probably still won't find one with just the GFCI there but I guess it isn't necessarily a requirement to pass that tool is it?
So if just using a GFCI is not sufficient, recently all of my copper pipes were replaced with PEX; however, the main line coming into the house to the internal water meter is still copper. Can I join all of the grounds to this? Seems like the perfect ground as it goes deep into the earth and then out to the city.
No Equipment Grounding
GFCI's but if I have a few properly grounded normal 3 prongs throughout the house as well then wouldn't it still all be up to code? Someone can plug their sensitive equipment into one of the other outlets instead – Eric F Feb 7 '19 at 18:14
