Metal consumer units with a 100A main switch are designed to provide electrical distribution and protection in accordance with BS 7671 (the IET Wiring Regulations) in the UK. These consumer units are typically used in residential, commercial, and industrial electrical installations, where the main switch serves as the point of isolation and control for the entire electrical supply. Here are some key points to consider when using metal consumer units with a 100A main switch in compliance with BS 7671:

Main Switch Rating: The 100A main switch is the device that allows the disconnection of the entire electrical installation from the power supply. Its rating is typically selected based on the anticipated load of the installation. The main switch should be capable of handling the maximum current demand without tripping.
Material and Construction: Metal consumer units are typically constructed from materials such as steel or aluminum. They offer durability and protection against mechanical damage and environmental factors. The construction should comply with the relevant standards and regulations, ensuring safe and secure housing for the electrical components.
Circuit Protection: Inside the metal consumer unit, circuit protection devices, such as circuit breakers (MCBs – Miniature Circuit Breakers) or fuses, are used to protect individual circuits against overcurrents and short circuits. These devices are typically rated according to the expected load of each circuit.
Residual Current Devices (RCDs): Metal consumer units may include RCDs for additional protection against electric shock and earth leakage faults. RCDs provide an extra layer of safety by disconnecting the power supply when they detect fault conditions.
Distribution of Circuits: The metal consumer unit distributes electrical power to various circuits within the installation. These circuits may include lighting, socket outlets, heating, and specialized circuits for specific appliances.
Earthing and Bonding: Adequate earthing and bonding arrangements are crucial for electrical safety. The consumer unit should be properly connected to the earthing and bonding system of the installation.
Circuit Labeling: Proper labeling of circuits within the consumer unit is essential for identification and maintenance. Clear labeling helps users and electricians identify the purpose and location of each circuit.
Location and Mounting: Metal consumer units should be installed in a suitable location that is easily accessible for maintenance and securely mounted on a wall or support structure.
Installation by Qualified Electricians: The installation of metal consumer units should be carried out by qualified electricians who are knowledgeable about local electrical codes and regulations. This ensures compliance with safety standards and proper wiring practices.
Testing and Inspection: Regular testing and inspection of the metal consumer unit, including the main switch, circuit breakers, and RCDs, should be performed to verify that they are functioning correctly. This includes the operation of the test buttons on the RCDs.

Metal consumer units with a 100A main switch are designed to meet the requirements of BS 7671 and provide a safe and reliable means of electrical distribution and protection. Compliance with the wiring regulations is essential for electrical safety and regulatory compliance in the UK. Consulting with a qualified electrician or electrical engineer is recommended when planning and installing a metal consumer unit to ensure it meets safety requirements and is correctly configured for the intended use.
