We&';ve standardized on a connector and we think you&';ll want to use it for patching and extending your waterproof cables. These can be used on older lights with old connectors, or to fix an accidentally cut cable. IP68 rated to 50 feet. Max Voltage: 48V Max Current: 3A Max Wire Size: 16AWG Each end is 22.8mm diameter and 66mm long. Connected together will be 160mm long. Instructions: Each Blue and Black end is a 3 piece assembly Unscrew the 3 pieces, puts the dome end and the middle core over the cable. Strip the wire insulation Insert the wires into the marked slots. Note that the "L" and "N" are marked on the Blue (source) and Black (load) sides. "L" for the hot, red, brown, or white wire. "N" for the neutral, ground, black, or blue wire. Tighten the 1.3mm hex threads with the provided hex wrench.
