1. Site visit

a) The purpose of site visit is to determine

b) Electrical equipment suitable for use

c) Maximum load demand

d) Single and three phase incoming supply

e) Type of wiring

f) Equipment arrangement

2. Determining consumer load requirement

With the aid of building floor plan the installation requirement such as the proposed load placement of electrical equipment and installation design plan can determine

3. Calculate maximum load demand

The estimate of maximum load demand is for determine the specification of the wiring equipment such as the cable and accessories and subsequently to install the electrical installation plan.

4. Submission of plan drawing and specification

a) Wire man with single phase restriction- low voltage single phase upto 60 amperes.

b) Wire man with three phase restriction- low voltage upto 60 amperes.

The planning flow chart for building wiring installation as shown in fig below
