size of the service entrance conductors.
Report as deficient breaker boxes that are? - ANSWER: Installed in hazardous
location/safety issues
What is the definition of a volt? - ANSWER: A volt is a measurement of the force or
potential energy in an electrical system (V=IxR)
, What is the definition of an ohm? - ANSWER: An ohm is a measure of resistance to
electrical flow in a conductor or insulator (R=V/I)
What is a brief definition of an amp? - ANSWER: An amp is a measure of how much
electrical current is flowing (I=V/R)
What is a brief definition of watt? - ANSWER: A watt is a measure of the rate of
electrical energy being consumed or released (P=VxI)

head, roof flashing.
Implications of an undersized service include: - ANSWER: nuisance tripping of the
main fuses or breakers.
After entering the service box, the neutral service entrance conductor should -
ANSWER: connect to the terminal with the grounding electrode and the service
neutral.
Double tapping is - ANSWER: the term for attaching two wires to a single fuse or
breaker terminal
Which of the following is a safety issue? - ANSWER: The main fuses have a higher
rating than the service entrance wire.
A 14-guage copper wire is protected by a 20amp fuse. You should report that -
ANSWER: this is a defect, and recommend improvement.
