this isn't exactly brewing related, but was brought to light by my recent addition of a 30A gfci breaker in my main breaker box.
The load center is a Square D QO20M which is probably at least 25 years old. It is a single neutral/ground bar setup at which the previous owner/DIY specialist took the liberty of adding some circuits to. They have doubled up 14ga grounds, which from what I read is OK. The problem I saw is they have also combined grounds and neutral's under the same lug in the bar. I know this is not to code, and I'm also pretty sure its not safe.
My question is, what is the best course of action? The label in the box says grounding kit PK9GTA can be added if necessary.
While that may be an option, I was wondering if cutting the main and simply removing all the neutrals and grounds and then attaching them properly (2 grounds per lug / 1 neutral) would work? There appear to be enough spots to attach all the runs for each circuit.
Again, sorry its not really brewing related, but I think its important before moving forward with my setup.
