Wiring porcelain lamp holder

Electrical Wiring: Wiring porcelain lamp holder

Electrical Wiring Question:

Hi! Background: I purchased a Leviton Porcelain Lamp holder with a pull chain, the rating is 660W 250V at Home Depot. The instructions for this device states that the BLACK (HOT) wire goes to the Brass Screw and the WHITE (Neutral) goes to the Silver Screw. But it does not say anything about the GROUND WIRE? Inside the Lamp holder it says to use CU and CUCLAD WIRE ONLY. I have purchased 14-2 NM-B Cerro wire for this project. Did I purchase the wrong wire for this lamp holder?

Hi Johansson - Great Question!
As long as the wire sizes of the new and existing wires match, then you got the right wire. CU refers to copper wire and CUCLAD refers to Copper Clad type wire. As for the ground, the lamp holder is non-metallic so there is no need for a ground wire being attached to it, in fact there is no provision to attach a ground wire

However if the electrical box which you are mounting this lamp holder to is metal or has a grounding screw then this is where you attach the ground wire.
