Mains and Sub Mains Systems

Mains Distribution

Mains distribution systems vary from something as simple as a sub main supply for a garage or shed up to large London commercial or industrial projects requiring a robust system.

The simplest system is a radial system. This is the cheapest and easiest to install. The downside of this is that a fault would lead to the loss of supply to multiple users. For example, in a hospital, a fault on a radial system would mean several areas would suffer a power outage, depending on where the fault lay.

Parallel feeders offer a greater reliability but are more complex and more expensive to install. These are, however, essential where high levels of reliability are required, such as in a hospital. Other distribution systems exist where costs justify the need for even more reliable distribution systems. These tend to be more expensive because they generally require a deliberate redundancy to be built into the network design.
