ANSWERS RATED A+
✔✔When should you megger a motor for its lowest insulation readings? -
✔✔Immediately after shutting down equipment.
✔✔In a start stop control circuit, an additional two stop buttons are to be added. These
stop buttons should be installed in which way? - ✔✔In series with the existing stop
✔✔Redline drawings are best described as? - ✔✔A way to show additional work and
changes to the system.
✔✔Redlines should be used to? - ✔✔Check the engineers
✔✔Best way to check a 4-20ma signal? - ✔✔Place DMM selector to mA and put leads
in series with the circuit.
✔✔What is the most important step when performing a megger test? - ✔✔Put the leads
together and verify a direct short
✔✔A diaphragm type gauge protector is used in which type of environment? -
✔✔Corrosive
✔✔You are the lead on a high priority critical pump repair. Your co-worker decides it's a
good time to take a break. You know that the job will take ten minutes if you have their
help. What should you do? - ✔✔A. Do the job yourself.
B. Get someone else to help you.
C. Calmly explain the importance of the job and that once it is done a break can be
taken.
D. Take a break and then do the job.
, ✔✔What is the characteristic of resistance in copper wire? - ✔✔It is inverse to its cross-
sectional area.
✔✔What is the maximum time between taking a class in NFPA70E? - ✔✔
✔✔the most common cause of electrical accidents among those that work with
electricity is? - ✔✔Contact with overhead lines, misuse of electrical cords, not using
equipment for intended purpose, not following manufactured guidelines.
✔✔You get called out to a lift station, the HMI screen is blank. What do you do? -
✔✔Notify operations to monitor the system while you troubleshoot and fix.
✔✔What appropriate steps to minimize affecting the process when tasked with fixing or
replacing an Influent Pump? Think these steps out, what makes the most sense. What
will not affect the process. What will reduce issues when doing the work. -
✔✔Troubleshoot, gather material, coordinate with operations, schedule date, create
work order, perform job, update work order.
✔✔When should information be documented to be revisited or reviewed at a later date.
- ✔✔Unauthorized person onsite, jobsite conditions.
✔✔You approach a piece of equipment that is off or not working, the circuit breaker is in
the tripped position, what is the best way to troubleshoot? - ✔✔Inspect the load side for
obvious signs of overloading, cautiously reset the breaker, amp check the load.
✔✔What is it called when someone teaches safety? - ✔✔Safety training
✔✔Why is it a good idea to have an experienced employee train new employee's? -
✔✔Pass on institutional knowledge
✔✔What is the most efficient way to train on a new piece of equipment? - ✔✔Get
everyone together and go over it together at one time.
✔✔What is the first thing to do if someone is being shocked? - ✔✔Remove the person
from the current
✔✔VFD works by adjusting the? - ✔✔Frequency
✔✔A soft starter works by? - ✔✔controlling the amount of voltage running through the
motors circuits. It does this by limiting torque in the motor. This in turn allows the soft
starter to reduce the voltage and allows it to gradually stop reducing the voltage to allow
for a smooth progression of current.
