How do you connect ordinary two wire wires? How to dock two wires

There are four empty openings below, and the color of the line above the four empty openings is yellow, green, red and blue, and then you can just connect the live wire to one by one, and connect the zero line to the blue line.

The ordinary two wires are the live wire and the zero line, the red one is the live wire, the rest of the colors are the neutral line, and the mixed color is generally the ground wire.

The wires of the two wires only have zero live wires, which can be connected arbitrarily under normal circumstances, and there are no requirements.

The general circuit AC only needs not to short circuit, live wire to live wire, neutral wire to neutral line.

Tools: Wire strippers, clamps, electrical tape ready. 1. Prepare wire strippers, clamps, electric tape, etc., if there is no wire stripper, you can use clamps or lighters to strip the wire.

2. Strip the wire with wire strippers, and insert the holes suitable for the size of the wire on the wire strippers according to the thickness of the wire (there is a mark at each hole of the wire stripper).

3. After the two wires for docking are stripped, cross the two wires and prepare for winding.

4. Wrap one wire head to another wire head first, be sure to wrap it tightly to avoid good contact (you can use clamps to wind the wire).

5. Next, wrap the other wire head to the winding wire as in step 4.

6. After the two wires are wound with each other, wrap the joints with electrical tape.

The regular three-core wire is the red (green, yellow) color wire is the power live line, the blue wire is the power zero line, the two-core wire only needs to be connected with these two lines, and the protective ground wire in the three-core wire (the specification is a color line) do not connect.

The function of the three-wire plug is to better protect the safety of the staff using household appliances with metal shells, so as to prevent the occurrence of fatal accidents caused by leakage and electric shock during use.

Three live wires in different phases, with a voltage of 380 volts between each of the two wires. It is generally used in the power system. Household appliances are generally powered by a single-phase power supply, and its three wires are the live wire, the neutral wire (neutral wire) and the ground wire, and the voltage between the live wire and the neutral wire is 220 volts, so this is not a three-phase electricity.

If you say that if a three-core wire is connected to a two-core wire, the two-core wire only needs to be connected to the two wires in the three-core wire, that is, only the power live wire and the power neutral line need to be connected. The regular three-core wire is the red (green, yellow) color wire is the power live wire, the blue wire is the power neutral line, the two-core wire only needs to be connected with these two wires, and the protective ground wire in the three-core wire (the specification is a color line) should not be connected.

Three lines of red, black, white, even two lines of black, how to connect red.

Prepare a pair of wire strippers, a pair of needle-nose pliers, and a pair of wire cuttersFirst of all, peel off the wire head of about 50mm, the two joints are superimposed on each other side by side, clamped with needle-nose pliers, fold one of the wires (A line) 90 degrees, and wind the other wire (B line), after the A line is wound, then fold the B line 90 degrees, and do the winding to the A line, after winding, trim with wire cutters to complete the docking。The specific steps** are as follows:

1. Prepare the wire strippers, use the wire stripper to peel off the end of the wire to be docked, the distance of the stripping is about 50mm, 2, the two wire heads side by side, the needle-nose pliers clamp the two wires in a suitable position in the middle, take one of the wires (assumed to be line A) and fold it up 90 degrees, 3. Let the A line to the other wire to be connected (assumed to be line B) to do the winding action until the winding.

4. Then according to the above (step 2 and step 3) method, fold the B line up 90 degrees, and do the winding action to the A line, 5. So far, the two wires are basically docked, and then the docking task is completed with wire cutters.

Problem 1: How to connect the wire joint. Two wires with copper wires inside.

How do I connect the connectors? Peel off the wires to expose 30mm long, twist the ends of the two wires with your fingers and put multiple thin copper wires together, cross them at 10mm at the root of the exposed copper wires (just like when connecting two sewing threads), pinch the two ends together (20mm) with your hands, clamp them with pliers and tighten them tighter; Fold it in half from the middle, change the length of 20mm to 10mm, clamp it with pliers at the bend to make the bend more dead, clamp the joint and the unscrewed wire together with pliers, and wrap it with adhesive tape.

Question 2: How to connect two wires and three plug-in wires Two wires, one is the live wire, the other is the neutral wire, and there is no ground wire. The connection method is very simple, connect the live wire of the power cord to the L connector on the socket bar, and connect the neutral wire of the power cord to the N connector.

Question 3: How to connect two wires with three wires** Three wires There is a two-color ground wire in it, and then use a test pen to distinguish between the live wire and the neutral wire, and then the two wires want to be connected with the zero wire of the live wire.

Question 4: How to connect the plugs of the two wires First of all, it is necessary to determine that the two wires are single-phase 220V AC power cords, and the three plugs are three-pole single-phase plugs. The wiring method is as follows:

Find out the live wire l and neutral wire n in the 2 wires, and mark them well;

Disassemble the single-phase 3-pole plug and wire it according to the principle of "grounding on the left zero and right fire".

The top pole piece is a grounding protection line, and if there is no one, it will not be connected to the stove. It is strictly forbidden to cross the neutral wire to the ground wire pole piece in the plug to make a protective grounding wire.

Question 5: How to connect the two wires Turn off the power first, test whether there is electricity with a voltage tester, and then dock the wires and wrap the insulating tape. Pay attention to the wire of the same color together, if the subordinate Geng leaks the protection, the zero line of the fire wire can not be reversed.

That's a safety hazard.

Question 6: How to connect two wires to three wires It is very simple, connect any three-phase live wire, and then connect a neutral wire to form a 220W single-phase electricity. This is because the voltage between the live wires of the three-phase electricity is 380 volts, and the voltage between the live wires and the neutral wires is 220 volts.

Question 7: How to connect the data lines of the four wires of the two lines of the mobile phone 5 points red line Connect the red line, and the power supply is positive.

White wire to black, power ground.

The other two green and white of the four wires are data cables, just ignore them.

Question 8: How to connect the socket cable? How to connect two wires 220V two wires are not distinguished, just connect them casually, question nine: how to connect two wires to three plugs?If you choose the wall socket of the three jacks, one end of the grounding wire in the wall socket is connected to one end of the wire, and the other end is nailed to the wall where the wall socket is installed with a steel nail, so that it can not be seen on the outside, and the problem of the grounding wire is solved.
