    "Distribution networks are normally formed by interconnecting a number of ring shaped grids. Distribution transformers are then connected to the system by T-offs. Instead of specifying and selecting individual components required for a T-off, the required components are frequently available in an integrated package known as a ring-main unit (RMU).

    Ring-main units normally consist of switches on both sides of the T-off, one to open the ring and another at the connection to the distribution transformer using one of the following:

    - Switch and a fuse separately
    - Switch-fuse combination"
