Keep your RV shore power connections clean, cool, and corrosion-free. Camco Power Grip dielectric grease protects electrical contacts from oxidation, improves conductivity, and lubricates prongs so 30 and 50 amp plugs slide in and out without the usual fight -- especially after a season of outdoor exposure.
Outdoor power connections take a beating. Rain, humidity, salt air, and UV exposure all accelerate corrosion on the brass and copper contacts inside your 30 or 50 amp shore power plug and receptacle. Corroded contacts run hotter, transfer power less efficiently, and can eventually damage the connector or the pedestal receptacle.
Camco Power Grip is a non-conductive dielectric grease formulated specifically for high-current electrical connections. A thin coat on the prongs before plugging in displaces moisture, seals out oxygen, and gives you a cleaner metal-to-metal contact surface. The result is a cooler-running connection and a plug that actually seats and releases without wrenching.
Seals contacts from moisture and oxygen to prevent the oxidation that causes overheating and power loss at the connection point.
Clean, grease-protected contacts maintain better metal-to-metal contact, reducing resistance and keeping connections running cooler.
Lubricates prongs so 30 and 50 amp connectors seat and release smoothly -- especially useful when receptacles are stiff from heat or weathering.
Works on RV shore power cords, trailer plugs and receptacles, generator outlets, and most other outdoor electrical connections.
This grease is appropriate anywhere you have an outdoor or semi-exposed electrical connection that sees repeated plug/unplug cycles or long-term static connection in a moist environment:
A corroded or dry 50 amp connection can develop measurable resistance, which shows up as heat. Heat accelerates insulation breakdown and, in worst cases, can weld a plug to a receptacle. Dielectric grease is a simple preventive step that costs almost nothing relative to replacing a shore power cord or campground pedestal receptacle.
Application is straightforward with the squeeze tube format:
Dielectric grease is intentionally non-conductive. It does not carry current between contacts; it protects the metal surfaces so that the metal-to-metal contact itself is clean and tight. Applying it to the prongs of a properly inserted plug is standard practice and will not cause shorts or reduce current flow.
At the end of camping season, apply a fresh coat of Power Grip to the prongs of your shore power cord before storing it. This keeps the contacts protected in storage and means the cord is ready to plug in cleanly next spring without needing to chase down a corroded connection at a campground.
