How to Use Dielectric Grease  

Question:

What am I supposed to do with this stuff? does in go onto the connectors before I push them together? Should I try and keep this off the contact surfaces of the electrical connections? If this stuff is conductive do I need to be concerned about excessive grease squeeze out of the connection and just wipe off the extra? ...etc - give me some basics on this goo please

Expert Reply:

You are correct. Place a small bead of the grease in your electrical connection before pushing them together. When the metal contacts of the connections push together, any grease between the actual metal-on-metal connection will be pushed aside (the grease is not conductive), but the remaining grease will surround the connection, acting to exclude moisture from the electrical connection. I would recommend wiping away any excess grease that would squeeze out of the connection.

If you click the link and fast forward the video to the 1:15 mark, you can see the grease being used in an electrical connection.
