Question 1

The transfer switch may not be located outdoors.

Answer 1

False

Question 2

Discuss the use of optional standby power generation systems.

Answer 2

Optional standby power generation systems include alternate power systems for applications such as heating, refrigeration, data processing, or communication systems where interruption of normal power would cause human discomfort or damage to a product in manufacturing, but where life and safety do not depend on the system.

Question 3
