The porcelain lamp holder usually has only one bulb, which can be controlled by a zipper or a light switch.They are often used in the basement and in the attic to provide basic light.This type of fixture is easy to install, and it is easier to replace if it is damaged due to the fact that the electric box it is connected to is already in place.
Turn off the light switch that controls the socket of the porcelain lamp.Turn off the power supply of the lamp head at the circuit breaker panel or fuse box.
Use your finger to screw the bare bulb off the socket in the lamp holder.Make sure it's cool before you touch the bulb.Remove the bulb to one side.
Unscrew and remove the mounting screws that hold the porcelain lamp socket on the electric box.Put the screws on one side.Carefully pull the lamp holder down to reveal the black and white wires attached to the underside of the device.
Place the contacts of the circuit tester on each wireCheck if there is no power on the wire.If the tester lights up, the wires are charged.Find the correct circuit breaker or fuse and turn off the power supply.Do not process the wires before confirming the power is off.
Loosen the two screws that hold the wire to the contact on the back of the lamp holder.The wire is now disconnected from the lamp holder.Put the lamp holder aside so that it can be discarded later.
Use a screwdriver to loosen the two contact screws on the lower side of the new lamp holder.Slide the black wire under one screw and tighten it with a screwdriver.Slide the white line under another screw and tighten it.Any thread can be attached to any screw.
Press the new lamp holder on the electric box and carefully push the wire back inside.Align the mounting hole on the lamp holder with the screw hole on the edge of the electric box.Fix the new lamp holder with the mounting screws you removed before.
Screw the bulb into the socket.
Restore the power supply at the circuit breaker panel or fuse box.
