I'll try again. I'm new here.

I want to use the 20 amp auxiliary breaker that is inside my meter pedestal next to the 200 amp main breaker. There is not a common (neutral) bar or a designated ground bar anywhere to be seen. There are occupied ground connections that I can slip into or hook onto a ground wire with a split bolt as the wire travels out from the pedestal towards a ground rod very close by. But the neutral wire has no obvious place to connect. Help?

Post a pic using "go advanced". Since this is where the first disconnect is, ground and neutral are the same point. You may need a lug or dual lug to make the connection. But don't lift grounds or neutrals UNLESS you know the consequences of doing it wrong.
