Question 264Electricity & Electronics - QMED
70% to passWhich of the following represents a characteristic of an ungrounded electrical distribution system?
AAccidental contact between one line and ground does not cause an outage.
BDouble ground faults on different phases will not cause an outage.
CGround detection systems are unnecessary.
DAccidental contact between one line and ground will always cause an outage.
AI Explanation
The correct answer is A) Accidental contact between one line and ground does not cause an outage. In an ungrounded electrical distribution system, there is no intentional connection between the circuit and ground. This means that a single ground fault, where one line accidentally contacts ground, will not cause an outage because the circuit remains energized through the other lines. The other answer choices are incorrect because they describe characteristics of a grounded system, where a ground fault would cause an outage.
