Porcelain is a ceramic material, and because of this, the question "devolves" into something akin to, "Is a ceramic light socket better than a ceramic one?"
Connect the ground wire to the metal box.
It's supposed to be non-conductive yet it transfers heat. Dielectric grease is often used with a heat-sink to transfer the heat better and it can also be used in applications where electrical components might get damp and/or hot and corrode. Most auto manufacturers are using dielectric grease or other grease compounds to protect light sockets and other electrical connections.
Plug a lamp into a working socket of an outlet to ensure the lamp works. Then turn off the switch and plug lamp into all outlet sockets, top and bottom outlets until the lamp doesn't light. Then turn on the switch and the lamp should light. Often a switch in a bedroom is only connected to one socket in a duplex outlet. It is possible to remove a jumper in an outlet to isolate the sockets for just this purpose. Often an electrician will install the outlet upside down (The third prong pointing up, to identify the outlet.
If you are referring to a porcelain or plastic ceiling light fixture most do not have a place to connect the ground wire. You cannot ground these type fixtures. Just connect the ground wire to the mounting crossbar and forget about connecting it to the light itself. It is on the ceiling and will never be touched unless you change the bulb and then you will have the switch in the off position. It is perfectly safe.
Dielectric grease would be a better choice.
Check/replace bulbs Check light sockets for corrosion Check light sockets for power/ground - if none check wiring to sockets
what is the difference between plug ang socket?
Bulbs are things that are plugged into light sockets, and they light up when the electricity is turned on.
It really depends on what you are needing. If this is for an air conditioner or ceramic heater, you may not need one that big. If this is for an outdoor light to light an entire yard, you may want the bigger wattage. ■
