Know more about distribution boxes and installation

A distribution box is an electrical enclosure used to house and protect electrical wiring, connections, and components. It is designed to distribute electrical power to different areas or devices in a building or facility. Here are some types of distribution boxes commonly used in electrical installations:

  1. Main distribution board: The main distribution board (MDB) is the central distribution point for electrical power in a building or facility. It receives power from the utility supply and distributes it to different sub-circuits throughout the building.
  2. Sub-distribution board: A sub-distribution board (SDB) is a smaller distribution box used to distribute power to specific areas or devices within a building. It is connected to the main distribution board and may have circuit breakers or fuses to protect against overloading.
  3. Junction box: A junction box is a distribution box used to join and protect electrical wiring. It is used to connect wires from different circuits and may contain terminal blocks or connectors.
  4. Terminal box: A terminal box is similar to a junction box, but it is designed to house and protect terminal blocks or other types of connectors. It is used to terminate and connect wires from different circuits.
  5. Floor distribution box: A floor distribution box is a type of electrical enclosure that is installed in the floor. It is used to distribute power to electrical devices in a specific area, such as a conference room or office cubicle.

Overall, distribution boxes are an essential component of electrical installations, providing a safe and organized way to distribute power to different areas and devices within a building or facility. They come in different sizes and types to suit different applications and can be customized to meet specific requirements.

Here are the general steps for installing a distribution box:

  1. Choose a suitable location: Select a location for the distribution box that is easily accessible and away from potential hazards such as water or heat sources.
  2. Turn off the power: Turn off the main power supply to the building or area where the distribution box will be installed.
  3. Mark the mounting holes: Hold the distribution box against the mounting surface and use a pencil or marker to mark the location of the mounting holes.
  4. Drill the mounting holes: Drill the mounting holes using a drill and suitable drill bit. Make sure the holes are the correct size for the screws that will be used to attach the distribution box.
  5. Attach the box to the wall: Place the distribution box over the mounting holes and insert screws into the holes. Use a screwdriver or drill to tighten the screws.
  6. Install the circuit breakers: Install the circuit breakers or fuses in the distribution box, following the manufacturer’s instructions. Make sure the breakers are rated for the correct voltage and amperage for the electrical system.
  7. Connect the wires: Connect the wires to the appropriate terminals or connectors inside the distribution box. Use wire nuts or other suitable connectors to join the wires securely.
  8. Label the circuits: Label each circuit with a suitable label or tag to identify the area or device that it supplies power to.
  9. Close the distribution box: Close and secure the cover of the distribution box, following the manufacturer’s instructions.
  10. Turn on the power: Turn on the main power supply and test the circuits to ensure they are working properly.

It is important to follow local building codes and regulations when installing a distribution box. It is also recommended to hire a licensed electrician for complex installations.
