When checking voltage, you must touch your meter leads where ---------
CORRECT ANSWER-----------------Across the load you are measuring
If you check each side of an element terminal to ground and you read 120
V, does that mean that the element has voltage to it? ---------CORRECT
ANSWER-----------------No
What size THHN wire should be used for a 20 amp load ---------CORRECT
ANSWER-----------------12 gauge
What size TGGT wire should be used for a 30 amp load? ---------
CORRECT ANSWER-----------------12 gauge
Give three common reasons for wire failures ---------CORRECT ANSWER--
---------------Undersized, temperature rating too low, poor connections
Why must burn or discolored wire be replaced? ---------CORRECT
ANSWER-----------------Once burned or discovered the current carrying
capacity drops significantly also connections will overheat
,If you put new terminals on discolored wire, what will happen? ---------
CORRECT ANSWER-----------------they will burn off again
Many high temperature wires installations will turn dark or brown after a
short period of time in high temperatures. What does this color change
indicate? ---------CORRECT ANSWER-----------------That the wax on the
wire has become hot from ambient conditions. The wire is usually still clean
and fully functional.
How do you know the switches motor rated? ---------CORRECT ANSWER--
---------------Has FLA or HP marked on the switch
Why are motor rated switches needed? ---------CORRECT ANSWER---------
--------To handle the higher motor starting amperage
Describe a pilot duty rated switch ---------CORRECT ANSWER-----------------
Switch rated at 1 amp or less, or rated in VA
Describe a power duty rated switch ---------CORRECT ANSWER--------------

To be able to turn a light on or off at two separate locations what kind and
how many switches are needed? ---------CORRECT ANSWER-----------------
Two three-way switches
, What does the letter B in the model number stamped on the side of an
infinite which signify? ---------CORRECT ANSWER-----------------Broiler
range switch
How does this broiler switch operate differently than a regular infinite
switch? ---------CORRECT ANSWER-----------------More adjustment at the
higher heat range of the curve
An immersion element that has the sheath split apart and swollen indicates
what? ---------CORRECT ANSWER-----------------the unit ran dry or "dry
fired"
What are stainless steel calrod elements normally used for in the
foodservice industry? ---------CORRECT ANSWER-----------------Fryers
What usually causes the terminal connections to burn off the end of an
element? ---------CORRECT ANSWER-----------------Loose or burned wire
connections
How much current does a short circuit draw? ---------CORRECT ANSWER--
---------------Infinite amps
If a circuit has two heating elements wired in series and each is rated at
120 V, what voltage must be supplied to the circuit in order for the elements
to heat at full power ---------CORRECT ANSWER-----------------240V
