Zero on the left and light on the right.
"Zero on the left and light on the right. There are two common sockets, two-hole and three-hole sockets. Among the two holes, the left hole is connected to neutral wire, and the right hole is connected to the live wire, and in a three-hole plug, the top hole is connected to the ground wire, the left hole is the neutral wire, and the right hole is the live wire. three-hole, the contacts from top to bottom are the upper electrode, the left electrode and the right electrode. There will be a rule of "zero on the left and fire on the right", which is considered safer. It means the regulations and regulations of the electrical installation. This regulation involves the safe use of electricity, so it is very important in the regulation of the electrical installation.
The left zero and the. right light are just a common wiring habit as shown in the figure below.above, it is not mandatory that double P air switches and leakage protectors have a left light and a right light. Just make sure the incoming and outgoing wires are consistent, i.e. the top incoming wire is the incoming wire. The left light and right zero wire are out. The left zero and right light actually mean that the left plug of the outlet is the neutral wire and the right plug is the live wire.
For the. Wiring must follow the principle of “zero on the left and light on the right”. I think many people who know anything about electricians know this. But if you ask them what the reason is, most people are probably stunned. Although this is common sense, if you go the other way there will be great hidden dangers for home electrical safety. Let’s share some common sense with you.
The so-called left and right zero. fire refers to what welet's do. When wiring, on a three-hole socket commonly used in the home, the left binding post is connected to the neutral wire (blue), the right binding post is connected to the live wire (red or *). *), and the middle position is connected to the ground wire (yellow-green color). The purpose is actually for our safety
According to the right hand of most of us. pulls and plugs in more frequently (left-handers express their frustration). Zero left and pull right When we use our right hand to remove or plug in the plug, leakage occurs and we can react immediately to release it. our right hand. Additionally, because the heart is on the lower left side of the chest, when the right hand is electrocuted, current will flow through the body through the right hand and form a circuit with the left foot. The current will not pass through the heart, thus preventing the heart from receiving an electric shock.
If the hand gauche is electrocuted, the current will form a circuit with the left foot and the heart. cause fatal damage to the human body, and according to effective statistics, the probability of electric shock on the right thumb is much higher than on the left hand. Therefore, when the right hand touches the metal part of the plug, from the left. The side is the neutral wire, when the plug is not inserted. It is not charged, so there will be no electric shock.
If the connection is reversed, it's no big deal, but the switch is on. the outlet will disconnect the neutral line. There is also electricity inside. If a child accidentally inserts their finger into the socket, there will be a risk of electric shock.
Whether it’s our electricians in China or. electricians around the world. Install the wiring of the sockets according to the limit rule of "zero on the left and light on the right". Only by following this principle can we avoids a greater extent the occurrence of electrical problems when our household appliances use electricity. Reduce the risk of cardiac shock and protect and ensure the safety of our people and property. Also consider doing this when wiring the outlets in your home.
