How to separate hot wires from neutral wires?
Separate the wires and strip the neutral and hot wires as follows. Using wire strippers (or a razor blade), cut ½ inch of the casing around the wire off, exposing the bare metal. Not to fret if you cut through the wire or cut into the wire, just cut back the outer case back a bit further and try again. Step 4.)
How to identify the neutral wire?
Step 2. ) Identify the wires. The neutral wire (white wire) will always be marked in some way: writing on the length of the wire, ribbing, a white stripe, or a thin white covering around the wire itself. If you cannot figure it out by looking at the cord, the neutral wire is more easily identified by the prongs. Modern appliance cords usually have two prongs of different sizes, so that you can only insert the plug into an outlet one way. With cords of this type, the larger prong always connects to the neutral wire. EXAMPLES SHOWN ABOVE.
