There are two main interpretations of "socket replacement": replacing a light bulb socket or an electrical outlet socket. The approach for each is quite different, so let's tackle both:

Replacing a Light Bulb Socket:

Replacing a light bulb socket can be a more complex task than simply changing a bulb. Here's what to consider:

Safety First: Always turn off the power to the circuit controlling the light fixture at the breaker box before starting any electrical work. Use a voltage tester to confirm the power is off before proceeding.

Assess the Situation: Identify the type of light bulb socket (e.g., screw-in, bayonet, track lighting).

Electrician: Replacing a simple screw-in socket might be manageable for comfortable with electrical work. However, more complex sockets or situations involving rewiring are best left to a licensed electrician.

If you decide to tackle a simple screw-in socket replacement yourself, here's a general guide:

Gather Materials: Screwdriver, replacement socket (ensure compatibility with your fixture)

Remove the Light Fixture: Depending on the fixture type, you might need to remove the entire fixture from the ceiling/wall or access the socket by unscrewing a cover plate.
Disconnect the Wires: Carefully disconnect the wires from the old socket. Note the color and position of each wire for proper reconnection.

Remove the Old Socket: Unscrew the mounting screws or detach the socket based on its design.

Install the New Socket: Connect the wires to the corresponding terminals on the new socket (match colors). Tighten the screws securely.

Reassemble the Light Fixture: Secure the new socket in place and reassemble the light fixture (if necessary).

Turn on the Power: Turn the power back on at the breaker box and test the new socket with a light bulb.

Replacing an Electrical Outlet Socket:

Replacing an electrical outlet socket is a more complex task  due to the higher amperage involved and potential rewiring. It's  strongly recommended to hire a licensed electrician  for safety and proper installation.

Here's what an electrician will typically do:

Turn off the Power: They'll ensure the circuit controlling the outlet is off at the breaker box.

Remove the Outlet: They'll carefully remove the cover plate and the outlet itself, disconnecting the wires.

Assess Wiring: They'll assess the wiring condition and make any necessary repairs or replacements.

Install New Outlet: They'll connect the wires to the new outlet following safety codes and secure it in the electrical box.

Test and Inspect: They'll test the outlet for proper function and ensure everything is up to code.
