OK, to clear up any confusion…
The first outlet I tested was outside. Plug in my Commercial Electric MS102H is GFCI Receptacle Tester. (home depot. about 8 bucks) and it shows open ground. No big deal. Not uncommon.
by the way, house built in 1987 so, everything should be grounded. OH, no additions or changes to the house since it was built.
Now, go inside and start testing kitchen outlets and again, all open grounds. Now I get my simple general twin lead tester and check the 3 prong dryer outlet. I get 240 volts with both hots but, cannot get a single 120 by testing one hot along with the ground. Every single outlet in the house is tested…Open ground.
So, there you have it.
By the way, thread not abandoned. I was out doing more inspections. Our Florida market is very busy right now. Not like we used to be in the 90’s. 100 to 130 inspections a week but, not bad for a recovering economy either.
