When wiring a Ceramic Lamp there are several things to understand. I will try to help you in this project.
Firstly how big is the hole in the top? If its 10mm or ½” (sorry these are the standard sizes) then you can use a Pottery Nipple to hold the lampholder in place. If the hole is from 14mm to 28mm then you can use a rubber bung. Once you have this fixing method in mind what type of lamp holder do you need.
Plastic, metal, switched or un-switched. If you has switched on the lamp holder then you don’t need a switch on the cable but of course if you would like to switch the lamp on at the cable then you don’t need a switch on the lamp holder. Also importantly if you have a metal lamp holder you will need a 3 core flex as you need to earth the lamp holder on your Ceramic Pottery Vase.
Next you also need to understand how you will stop the cable being pulled. Imagine someone swinging the lamp around by the wire, you need to stop the wires being pulled out of the terminals and to do this you need a cord grip or strain relief. There are several ways to do this but the easiest is to put the strain relief on the cable just behind the hole where the wire comes out on the Ceramic Vase.
If you cant get the wire down inside the Ceramic Vase base then you can use a male / female adaptor that spaces the lamp holder up about 30mm and allows for the cable to come out just under it. These have a 10mm thread so make sure the fixing in the ceramic base is 10mm, the rubber bungs are.
Lamp holders have some form of cap that you can fix in place first before you worry about the wiring. Using either the pottery nipple, rubber bung or why not look at our accessory kits as these are designed to that purpose.
So once your fixing is in place, pass the cable through the side hole of the Ceramic Vase, add the strain relief and pass the cable up through the fixing. Wire the lamp holder and secure it in place. All electrical work should be tested before use but that’s not easy so be sure it’s wired correctly.
