questions about my panel


I was looking inside my panel a few days ago and noticed a few things. There seems to be some sort of buildup or corrosion on the screws of the breakers. These are not the screws holding the wire in place, they seem to be holding the breaker together. Is this an issue? The panel is in a basement.
The other thing I saw was all the neutrals and grounds share a screw on the neutral/ground bar. The panel looks clean and well done so I wouldn't think a pro would mess up something that simple. The house was built in 1995 if the code has changed regarding this issue, thanks.

questions about my panel


The neutrals and grounds sharing a single hole is a code violation, the white stuff on the breaker might just be part of the manufacturing process? not sure what it is...

It is a sealant in a hole. Yes, it is normal and part of the manufacturing process.

You can ignore that white stuff adjacent to the terminals. It's part of the manufacturing process and resembles porcelain.

Yup, exactly.
I bet it is hiding a critical screw they do not want you to get at.

They don't want you to let all the magic out.

Most likely a calibration screw. Most breakers have them, hidden behind a certification or lot# sticker...

#6 would be the calibration screw in the picture.

Thanks for the replies about the breakers. Should I worry about the ground/neutral issue or leave it alone?

Lets see, the panel has been installed since 95, yeah, I wouldn't lose much sleep at this point.

it is an easy fix through, just make sure you turn off the breakers first, or you could end up with a nasty surprise.
