Not sure why my question makes no sense, but all of the expense for this job is falling on us, the condo owners and not the association. The condo association came to us and said that we need to install the Alumi Conn connectors because our apartments had aluminum wiring and the insurance company that insures the association claimed that aluminum wiring was a fire hazard so they said we needed to install the Alumi connectors. They hired this big electrical contracor to do the job which I felt to be kinda sneaky and I felt that the price of $700 was too high, so I bought the connectors myself and asked an electrician friend to help with the job. Ok, easy enough. Then we applied for the permit and the inspector called the electrician today to just let him know what was expected so that the job would pass. Thats when we were told about the ground bar because as I understood there are 8 wires in the box that are all connected together and I guess by having the ground bar, each of these wires would be separate. This is all new to me; I knew nothing about a class action suit. Basically I came across this website and hoped that someone could help me find what I was looking for. Its difficult to ask questions when you really don't have a good understanding as to the reasoning behind these questions, which I did make clear when I said that I had no electrical knowledge; I was just reaching out to someone who could share their knowledge with me.
