Re: how to determine wire polarity
Ok, disreguard my PM, I'm way off. So you just got a standard 110 3 prong plug on one end, the other 3 bare wires? Your meter should have a continuity tester, if youtouch your two probes together, its beeps. hold one on the round ground prong of the plug, and touch the other to the other end of the 3 wires, only one will make continuty. Thats your ground. The other two are your nutral and hot wire, in a typical wall recptical, the wider of the two flat prongs is the common ground, and the narrower prong is the hot (Usualy black in 110 vac home wiring). Be carefull, your dealing with enough current and voltage to hurt your self or light your house on fire.
