[QUOTE="ATL Royals, post: 154203, member: 100750"]I wouldn't worry too much about the solvents. If it's really oil-based grease, it's intended to lubricate metal-on-metal contact. Strong solvents would damage the metal, completely negating the effect of the grease. I doubt the solvents are anything more than mild detergents. I could be wrong, but I doubt there's more to it than that. More concerning is that he's using a product rated for plumbing in an electrical environment. I had difficulty finding "Oatey Flanges Plumber's Grease," but they seem to have 2 current products, a 300 degree grease and a silicone grease. The 300 degree grease is oil-based, which means it's chemically organic, which means it's flammable. Even if he properly grounded it, any lightning strike would almost certainly ignite the grease, and I wouldn't rule out the grease igniting from the electrical activity going through his system. The silicone grease is less concerning, but it's also an organic polymer. In either case, there are products available to waterproof outdoor electrical connections. Using a plumbing product isn't a good idea.[/QUOTE]
