Here are some pictures that show the plug and weatherproof cover, along with the extension cord in use for the winch.Yes, they are keyed differently for using different voltages, so you don't plug a 36v forklift into a 48v charger. I just use grey, they are usually the cheapest. I made a jumper cable extension cord with SB350s on both ends that I use with my winch in the rear or to jump start other vehicles. I made myself an adapter from a SB350 to a smaller size, so that I can plug my air compressor into the same plug, without putting the SB350 sized plug on the smaller devices.
not quite true. They don't mate to each other like the small connectors do, but the SB175s have two thru holes for bolting a large pull handle to them. You can use those to stack multiple plugs together (and I will be).this is all because they are one piece, the smaller <45A powerpole's can be keyed differently depending on how you hook em up.. like instead of side by side, you can stack em ontop of eachother.. or have one up, and one side facing, or both, could also use nulls.. so those are inherently easy to design a multi-voltage, multi-conductor system and prevent accidental connections..
The big powerpoles dont have that feature built into its design, so they had to make color keyed connections.
Warn uses red, Ramsey uses blue, Superwinch uses gray. At least the wiring kits I've bought from each of those mfg's used those colors. I've also got some of the black 'key-less' ones that I've purchased in the past for making adapters. from one color to another.Does anyone have any experience/knowledge of what color Anderson SB175 will mate with the version that Warn uses? (I would guess Red, but that is kind of Warn’s factory color as well).
