Which of the following is true of an emergency generator installation?
- A.The generator should be operated in a well-ventilated area (correct answer)
- B.The generator must be insulated from ground
- C.Fuel should be stored near the generator for rapid refueling in case of an emergency
- D.All these choices are correct
WhyAn emergency generator should be operated in a well-ventilated area. An emergency generator burns fuel and produces carbon monoxide, so it must be run in a well-ventilated area to avoid a buildup of that dangerous, invisible gas, answer A. The generator's frame should actually be properly grounded, not insulated from ground, and storing fuel near a running, hot generator is a fire hazard rather than a safe practice, so B and C are wrong, and since they're wrong, D's "all of these" is wrong too.
