Electrical distribution boards

Hager has launched a free technical guide about Type B distribution boards and how to meet the requirements of the 17th Edition and Part L2 of the Building Regulations for commercial installations. The whole nature of sub- and final distribution has changed over the last few years. There is a greater demand for RCD protection, and sub-metering is now a requirement.

This 24-page guide covers the selection and erection of equipment, cable entry into a distribution board, isolation and switching, and protection against fault current, electric shock and overvoltage. It also includes advice about metering and sub-metering and also the use of control devices to help reduce energy consumption.
