Σύνοψη

The purpose of the work carried out, is to design
the electrical installation and telephone installation
of a multistorey building pertraining to a block of
flats and shops. The approach followed satisfies the
15th edition of the lEE Wiring Regulations, the E.A.C.
conditions of supply, and CY.T.A. requirements.
The installation is properly designed, so as to
'cover everything concerning the proper and safe
operation of all electrical equipment installed in the
building. Proper materials and equipment are used for
protection against overcurrent and earth leakage
currents. Protection against overcurrent is achieved
with the use of miniature circuit breakers and against
earth leakage with the use of residual current devices.
The installation is separated into group of circuits.
An isolator is used in each group to isolate the supply
during maintenance. Where more protection is required,
for instance in the case of a motor, an isolator is use
especially for the circuit, and an extra protective
device is installed (starter) to give overload protection.
Illumination design is carried out by using "Lumens" method of calculation. It is the most widely used approach to the systematic design of Interior lighting. Light Loss factor is used in this method to estimate what the illuminance produced by the installation will be at any particular stage of its life, the depreciation caused by dirt deposited on luminaires, and room surfaces.
Telephone installation is carried out for all flats
and shops. Finally the costing of the whole installation is
estimated by calculating separately the material and
labour cost (analytical method). By this way sufficient
results are obtained.
