While both methods yield a safe and compliant electrical system, the plug-on neutral approach requires less material by eliminating the short pigtail wires. Panels designed for PON technology feature a specialized metallic bus bar running parallel to the standard hot bus bars. If you splice through the outlet screws and one outlet goes down, every other outlet down the chain will go down and you'll have to. Your PSU may have come with two separate PCIe 8-pin cables - one with a single 8-pin PCIe connector, and another with two 8-pin PCIe connectors, which we refer to as "pigtail". But is using the pigtail cable safe? Or should you use two individual 8-pin cables? Spoiler alert: Pigtail cables are safe. I have always thought that the best way to wire a receptacle is to use a pigtail lead from the supply wires to the receptacle. My electrician prefers to run the supply wires, and also the wires to the downstream receptacles, to the screw terminals at the back of the receptacle. When receptacles are. My switch didn't come with pigtail wires and I didn't have any extra wire lying around, so I couldn't do the recommended approach (install a third pigtail wire coming out of the neutral wirecap, and connect that to my switch's neutral terminal). Instead, I just connected the two ends of the neutral. These connectors can be a big help when you need to connect two wires, repair damage, or extend a circuit connection without having to strip or solder the wire yourself. You may have seen them repair your car, install a new light fixture, or even work on industrial equipment.
