The three wire feed to the sub panel is a 2" conduit. I email City Building Dept and they were not very helpful, "modern sub panel usually have separate bars." From what I understand is, it's safe to put ground and neutral wire on the same bar. Installing a ground rod next to the...

I have a diagram to better illustrate my setup. Since I'm installing an mini-split ac, to be on the safer side, can I just install a ground rod next to the condenser and ground the condenser. Would this make it safer?

Terry, I have a water hammer problem in my 3-unit complex. I believe I know where the problem is. In the early morning, when Unit A, shuts off water after taking shower, I can hear a loud noise, it gives me a heart attack ever time I hear the sound. I already installed Sioux Chief at the...
