Question 1 of 10
What unit is used to rate generators, especially on the load side?
Generators are rated in kVA, but on the load side, the rating is often expressed in kW.
Question 2 of 10
Which of the following loads typically has a higher starting wattage than its running wattage?
Inductive loads, such as motors and air conditioners, draw a much higher current at startup.
Question 3 of 10
What is the formula to calculate the wattage rating of an appliance?
Power (P) in Watts is calculated by multiplying Voltage (V) in Volts by Current (I) in Amperes.
Question 4 of 10
If a device has a voltage of 120V and a current of 0.8A, what is its wattage rating?
P = V x I, so 120V * 0.8A = 96W
Question 5 of 10
What is the equivalent of 1000W?
The prefix 'k' (kilo) means 1000, therefore, 1000W is equivalent to 1kW.
Question 6 of 10
What does ATS stand for in the context of generator installation?
An Automatic Transfer Switch (ATS) is used to connect a generator to a building's electrical system.
Question 7 of 10
What should be considered when sizing a generator for high inductive loads like air conditioners?
High inductive loads have a large inrush current when starting.
Question 8 of 10
When sizing a generator for a home, what should you do regarding the wattage ratings of appliances?
You need to consider the total load by adding the wattage of all appliances.
Question 9 of 10
What is a 'demand factor' used for in generator sizing?
Demand factor considers the probability that not all appliances will run simultaneously.
Question 10 of 10
In the example calculation, what is the impact of a motor's starting current on sizing?
Motors draw a much higher current at startup, influencing the generator size needed.
