Greasy Residue in Circuits?
Question:Recently a lot of my fuses have blown, and when I went to replace them, I noticed greasy residue in the circuits for holding the fuses. Is this normal? And if not, what is the problem? And, is there any safe way to clean them?
Answers:
A previous owner probably used dielectric grease. It's probably not necessary but I wouldn't clean it out. I doubt if that is the source of your blown fuses.
It is possible that someone put an anti-oxidation agent on them to prevent breakdown of the metals. When 2 different metals come in contact with each other, they will eventually oxidize.
you can clean but first you MUST switch off or pull the breaker/fuse if its a non-main panel meaning there is no main than the line side of the panel fuse box will stay 'hot' the only way to turn this type off is to pull the meter blowing fuse's sounds more like a overload on one or more of the branch ckts I would replace all fuse's with new ones time delay type fuse's as the same with breakers over time get weak and will trip/blow faster as they sense heat buildup from current flow as well as short ckt
