Re: Dielectric grease on connections
Dielectric grease is an insulator. Do not use it on the contacts or connections themselves. For low-voltage circuits an expensive dielectric grease is not needed. Those greases are for high-voltage applications. The grease is applied to help seal the connector. It is not applied directly to electrical contacts.
I disagree. I personally use it on most all of my electrical connections with no known issues. I especially use it on light bulb bases. Permatex is one manufacturer of dielectric grease. This is what they say on their web site.
Protects electrical connections and wiring from
salt, dirt and corrosion. Extends the life of
bulb sockets. Prevents voltage leakage around any electrical connection. Also prevents spark plugs from fusing to boots. Required for modern high energy ignition systems.
Suggested Applications:
Marine and automotive electrical connections, spark plug boots, trailer hitches,
battery terminals.
They also say, for another type of dielectric grease, the following...
Permatex? Bulb/Lamp & Electrical Connector Dielectric Grease
Increases performance and extends service life of bulbs and lamps by preventing voltage leakage and protecting electrical connections from moisture, dirt and corrosion. Great lubricating properties ease the disassembly process. Protects rubber, plastic, ceramic and metal surfaces.
Suggested Applications: Headlamps, lighting bulbs for: instrument panel, glove compartment, inside door trim, interior courtesy lamps, parking and turn signals, brake lights, license plate lights, trunk and hood lamps; also for fuses, battery terminals, ignition components and other electrical connections.
Admitedly, some of this is manufacturing hype, but some of it is appropriate.
So... Has anyone ever seen any issues that they can actually blame on the use/misuse of dielectric grease?
