There is only one way to insert a triangular plug into a triangular socket. Normal ungrounded two-pole plugs can also be plugged into one of the connections on the hot side. To avoid this, the containers are polarized, which means that the neutral pin is wider than the hot pliers.
A standard 110 volt AC outlet has no good and bad sides. It is a warm and neutral side. The wider groove in the drain should be on the neutral side and the narrower groove should be warm.
A little hard to read, but it has hot wire on the left and white wire on the right. Place the black threads on the warm side and the white threads on the left side. First connect the ground wire to the green screw on the bottom of the socket.
As you can see, the neutral wire and hot wire connect to the two vertical pins on the top of the can (neutral left, hot right) and the ground wire connects to the round terminal on the bottom of the can. Container. .
Connecting a 3-pin plug The power cord consists of a white cord, a green cord, and a black cord. The white wire is connected to the silver or light screw, the green wire is connected to the green screw, and the black wire is connected to the gold or dark screw.
The power cord supplies high voltage to the device. The neutral conductor closes the circuit and draws the current away from the device. The third wire, called the ground wire (green / yellow), is a safety wire that connects the metal housing of the device to the ground.
The smaller tip is warm and the larger one is neutral. And yes, the current changes direction (oscillates from positive to negative) 60 times per second (a sine wave) and cannot do this on a single wire, it needs the neutral line to complete the circuit.

know what is the color of each wire in the circuit
Yes, you can replace a two pin plug with a 3 pin plug, just connect the third pin (ground) to nothing. It is not the other way around: never replace a three-pin plug with a two-pin plug.
The National Electrical Code (NEC) requires receptacles with a third receptacle for grounding plugs. If you remove the third pin, the item you are using has no security basis. It is dangerous to use three sockets on one socket. The third pin is a reason to protect yourself in the event of a breakdown.
Remember that when repairing lamps, the conductor of the neutral is marked in the wire of the lamp (usually with a rib or rib) and at one end it connects to the wide blade of the plug and the screw of the neutral (usually silver but can have a different marking) have) on the other hand.
The neutral will most likely be white and the hot wire will be red or black, but try to be sure. Identify the neutral conductor in the lamp by looking at the wires. In most modern lights, the neutral wire is white and the hot wire is red or black.
On a two-prong plug, if the wider pin is neutral, the narrower pin is hot. Neutral (wider pin) is connected to the ribbed conductor, hot (narrower pin) is connected to the non-ribbed conductor.
The left sulcus is called neutral, the right sulcus is called warm, and the hole below is called the bottom. The pins of a plug fit into these slots in the socket.
The only way to be absolutely sure you have found a neutral wire is to check the voltage (110V / 120V) between the white wire and the hot (usually black) wire in the box. With a standard switch / dimmer, the heater uses one of the two wires connected to the switch.
Disconnect each extension cable from the colored screws in the socket in the following order. Attach the black wire to the copper-colored screw. Attach the white thread to the silver screw. Insert the green wire into the green screw and tighten.
