VERSION
The grounding electrode conductors may also be called: - Ground Wire
The grounding systems are connected to the house neutral at the: - Service Box
From the point where the ground and the neutral wires connect, there are two paths to
ground. What are they? - 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 - More electricity can flow at a lower
amperage rating.
Gas piping, "black pipe", can be used as a ground. - FALSE
15 amp breakers use what gauge wire? - 14 Gauge
20 amp breakers use what gauge wire? - 12 gauge
30 amp breakers use what gauge wire? - 10 gauge
40 amp breakers use what gauge wire? - 8 gauge
As it relates to fuses, what is a safety concern? - A fuse that is too big.
The grounded service conductor is called: - The neutral.
An overcurrent protection device can be what? - A fuse or a breaker
Which of the following suggest an improperly supported service drop? - Missing drop
loop
Which of the following is a reliable indicator of service amperage? - The size of the
service entrance conductors.
, Report as deficient breaker boxes that are? - Installed in hazardous location/safety
issues
What is the definition of a volt? - A volt is a measurement of the force or potential
energy in an electrical system (V=IxR)
What is the definition of an ohm? - 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? - An amp is a measure of how much electrical
current is flowing (I=V/R)
What is a brief definition of watt? - 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? - 0 feet or as short as
possible.
Service laterals are installed where? - Underground
What is a common problem with service drops? - Proper clearance from roofs.
What are two common problems with service entrance conductors? - No drip loop and
no mast head.
What are 3 common areas of water penetration? - Conduit joists, mast head, roof
flashing.
Implications of an undersized service include: - nuisance tripping of the main fuses or
breakers.
After entering the service box, the neutral service entrance conductor should - connect
to the terminal with the grounding electrode and the service neutral.
Double tapping is - the term for attaching two wires to a single fuse or breaker terminal
Which of the following is a safety issue? - 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 - this is a
defect, and recommend improvement.
What is a suitable location for a branch circuit wire? - Stapled to two by four studs.
