Answer the following statement(s) true (T) or false (F)
1. Temporary currents flowing in the circuit until the overcurrent device opens are considered “objectionable” and are not permitted.
2. Due to data processing equipment being sensitive to electrical noise on the equipment grounding conductor, it is permitted to isolate the equipment from the “dirty ground” and connect the equipment to only a local ground rod.
3. Electrical systems that are permitted to be installed as ungrounded are usually not grounded
so the first ground fault on the system will not result in operation of an overcurrent device.
4. The owner of the premises can choose whether the following circuits are grounded or
remain ungrounded: a crane that operates over combustible fibers, circuits in inhalation
anesthetizing locations of hospitals, and 15-volt circuits for swimming pool lighting derived
from a transformer.
1. FALSE

3. TRUE
4. FALSE
