Schools electrical installation

Electrical installation design for schools should be simple and economical. It must also be practical and functional.

Among the educational buildings, primary and secondary school buildings are the most common. Yet their numbers are still insufficient to cater for the high increase of enrollment throughout the country.

The construction of new school building by the education ministry has been increasing at a very high rate in the last few years. The design of the electrical system stresses more on the functionality and practicality of the system. The fundamental concept of the design is to ensure maximum safety and to keep maintenance requirements to the minimum. That also means that spare parts that will be needed for maintenance throughout the life of the installation should be easily obtainable locally and low-cost.

Other than the primary and secondary school building, the educational institution has the higher learning institutions such the universities technology institutes polytechnics, teachers training colleges and youth skills training centers.

These institutions have other criteria that set them apart from school building as educational buildings. In designing the electrical installations for these buildings, other that the factors of safety and functionality, special considerations should also be given to the factors of aesthetic values and the possibilities of future extension of the campuses or the building complexes.

Usually educational institutions like these consist of many separate large buildings like the administrative block, the staff quarters, the student hostel blocks, academic buildings, libraries, lecture theaters, halls and lecture halls. A few substations are usually required and they are usually located at large load centers throughout the campus.

These types of educational institutions usually have large campuses where many individual building are located far apart. As a consequence the electrical distribution system requires the use of higher distribution network. Proper switching arrangement between the various substations is usually designed for to ensure the continuity of supply and also to allow for ease of maintenance on the installation network.

A certain arrangement may also be worked out with the electricity supply authority regarding the design of the distribution and provisions of separate individual meters (which are separately billed by the electricity supplier i.e. canteen operators and retail shop operators) at certain facilities on the large campus.
