I’m taking a look at the (only) panel in my apartment and I’m noticing that out of all the circuits leaving the panel, not a single one of them contains a ground wire. Only hot(s) and neutral. On closer inspection I can see the ground wire coming in through the top, it connects to the ground bar, but there are no other wires attached to the ground bar.
The 120v circuits leave the panel with just a hot and a neutral and the 240v circuits exit in bunches of 2 hot and 1 neutral.
Are all these circuits ungrounded? Is it likely or possible that these circuits get their ground from somewhere else that is not the panel in my apartment? Are these circuits meeting up with ground each on their own somewhere on the way to the outlets or is it another common point?
