I have a question hopefully I can get some help on. I was troubleshooting a recepticle in co-op apartment that is not working. I went to the circuit breaker panel and when I opened the panel door I noticed the ground going out to all the receptacles is tied to the neutral bar and there is no ground tied to the actual ground that coming in to the panel. I have heard this ok on some panels and not ok on other panels. I have a feeling this a big no-no and I should switch it out. Should I?
