4Leiter

4Leiter, also known as 4-wire or 4-lead, is a type of electrical wiring system used in residential and commercial buildings. It consists of four separate wires: two live wires, one neutral wire, and one ground wire. The two live wires are typically colored black and red, while the neutral wire is usually white. The ground wire is often green or bare.

The 4Leiter system is designed to provide a safer and more efficient electrical supply. It allows for the use of two separate circuits, which can be used to power different appliances or lighting fixtures. This can help to reduce the risk of overloading a single circuit and can also make it easier to manage the electrical load in a building.

The 4Leiter system is also more flexible than other wiring systems, as it allows for the use of different types of electrical devices. For example, it can be used to power both incandescent and LED lighting fixtures, as well as appliances that require a higher level of power.

In terms of installation, the 4Leiter system is relatively straightforward. The wires are typically run through the walls and ceilings of a building, and are connected to electrical outlets and switches using standard electrical connectors. The system is also designed to be easily expandable, as additional circuits can be added as needed.

Overall, the 4Leiter system is a reliable and efficient way to provide electrical power to a building. Its use of separate live wires and a dedicated ground wire can help to reduce the risk of electrical hazards, while its flexibility and expandability make it a popular choice for many residential and commercial projects.
