ICIT: Quiz on Electrical Drafting and Design

What is the primary purpose of scale drawings?

• To create artistic representations

• To allow proportionate representation of objects

• To simplify complex designs

• To enhance visual appeal

Which type of drawing is used to show the layout of a building?

• Wiring diagram

• Block diagram

• Schematic diagram

• Site plan

What does a wiring diagram primarily communicate?

• The structural integrity of a building

• The geographical location of a site

• The interrelation of electrical components

• The aesthetic design of a building

What is the maximum demand in electrical terms?

• The total power consumption of all devices

• The peak voltage in a circuit

• The minimum load capacity of a circuit

• The average current required at any one time

What is the formula for calculating diversity?

• Diversity = Installed loads / Maximum Demand

• Diversity = Maximum Demand / Installed loads

• Diversity = Maximum Demand + Installed loads

• Diversity = Maximum Demand - Installed loads

What is the average demand of an installation?

• The total connected load of all devices

• The average power requirement over a specified period

• The minimum power requirement for safety

• The maximum power requirement at peak times

What is the purpose of short circuit calculations?

• To predict prospective short circuit current

• To calculate the average demand of a circuit

• To determine the total load of an installation

• To assess the efficiency of electrical devices

What does PSCC stand for?

• Power Supply Current Capacity

• 200 W

• 100 W

• 50 W

• 150 W

What is the purpose of using a diversity factor?

• To improve the efficiency of electrical devices

• To enhance the safety of electrical installations

• To reduce the size and cost of conductors

• To increase the load capacity of circuits
