Question: Analyze a plan for feeder and branch circuit wiring incase of AIUB. For feeder circuit
wiring please address these issues like type of wire, public health issues, safety issues, societal and
environmental issues as well. For branch circuit wiring, selection procedure is little bit different than
the feeder circuit. You need to focus in these topics like wire selection, classification, market
research, safety percussion and health issue as well. Please make a power point presentation along
with a clear video demonstration and send the link of your demonstration in my mail.
Design of a Single Line Diagram (SLD) 400V
AC Power Distribution.
General Notes:
a. This Single-line diagram shows the electrical system functional design. For equipment
details refer to specific vendor supplied drawings. For installation details refer to specific
layout and arrangement drawings.
b. The installation shall be in accordance with the requirements of: IEC, where the
requirement of those drawings differ from the above regulation.
c. The electrical system shall be designed:
• 1000kV/400V transformer operating.
• Circuit Breaker frame sizes are typical.
• All cables are to be from bottom using removal type.
• Necessary earthing terminal to be provided.
• All electrical fittings shall be suitable for ambient temperature.
• Insulated copper bus bar shall be in accordance with latest IEC requirement.
• To prevent the standby transformer from being energized by the main
transformer.
Single Line Diagram
The single-line diagram is the blueprint for electrical system analysis. ... It shows a correct power
distribution path from the incoming power source to each downstream load – including the
ratings and sizes of each piece of electrical equipment, their circuit conductors, and their
protective devices.
Fig: Single Line Diagram.

Fig: Circuit Diagram of Single Line Diagram.
A single line diagram, also referred to as a one-line diagram, is usually a single page document
that represents a facilities electrical distribution infrastructure. It will have one single line shown
for bus (or cable) to represent all three phases.
