The grounding electrode conductors may also be called: - ANS Ground Wire
The grounding systems are connected to the house neutral at the: - ANS Service Box
From the point where the ground and the neutral wires connect, there are two paths to ground. What
are they? - ANS Through the neutral wire or through the grounding electrode conductor to water pipes
or grounding rods.
What is the advantage of a 240 volt circuti - ANS More electricity can flow at a lower amperage rating.
Gas piping, "black pipe", can be used as a ground. - ANS FALSE
15 amp breakers use what gauge wire? - ANS 14 Gauge
20 amp breakers use what gauge wire? - ANS 12 gauge
30 amp breakers use what gauge wire? - ANS 10 gauge
40 amp breakers use what gauge wire? - ANS 8 gauge
As it relates to fuses, what is a safety concern? - ANS A fuse that is too big.
The grounded service conductor is called: - ANS The neutral.
, An overcurrent protection device can be what? - ANS A fuse or a breaker
Which of the following suggest an improperly supported service drop? - ANS Missing drop loop
Which of the following is a reliable indicator of service amperage? - ANS The size of the service entrance
conductors.
Report as deficient breaker boxes that are? - ANS Installed in hazardous location/safety issues
What is the definition of a volt? - ANS A volt is a measurement of the force or potential energy in an
electrical system (V=IxR)
What is the definition of an ohm? - ANS 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? - ANS An amp is a measure of how much electrical current is
flowing (I=V/R)
What is a brief definition of watt? - ANS A watt is a measure of the rate of electrical energy being
consumed or released (P=VxI)
In most areas, for what distance can service entrance wires run inside the building before going into the
service box without special permission? - ANS 0 feet or as short as possible.
Service laterals are installed where? - ANS Underground
What is a common problem with service drops? - ANS Proper clearance from roofs.
