How do I replace the cable on a modern chrome floor lamp
i have bought a modern chrome floor lamp that has a dimmer switch attached to the cable,but the wire was not long enough to reach to the plug so thinking i could just cut it and add more wire that is what i did,now the lamp will not work at all and i do not know how to open the unit at the top of the lamp to replace the wire
I'm no electronics expert but I would check for polarity.
Question: do you have the original plug? If so, is it two prongs or three? Most lamps are two. Assuming you have the original plug and it's two prongs, I would bet that one plug prong is bigger than the other. That means your device is polarized. It matters which wire goes where in the outlet.
Look on your lamp cord and you should see that one side is molded differently than the other. One is usually smooth and the other has some sort of texture or ribbing. If you added more wire between the lamp and the plug, make sure that the smooth wire on the lamp is connected to the smooth wire on the plug.
I am guessing that your lamp is polarized and that you mixed it up when you added the extra wire (easy to do).
Now, why would it make a difference? Our household alternating current circuits consist of a 'hot' and a ground. The ground literally is connected to the ground outside your house. The hot comes from the power company and it does all of the pushing and pulling of electrons in the circuit.
Again, I am no expert but I would bet you that the dimmer you have expects that hot wire to be on one side or the other.
