◉ At the drip loop you notice that the service drop conductors are
smaller in diameter than the service entrance conductors. You
should conclude
A)
that the service entrance conductors must be aluminum, and report
them as such.
B)
that this is a normal situation, and is acceptable.
C)
that the house service must be 200A.
D)
it was a faulty installation and should be corrected.. Answer: The
answer is THAT THIS IS A NORMAL SITUATION, AND IS
ACCEPTABLE. The service drop conductors can be smaller than the
service entrance conductors because the service drop conductors
are in free air, whereas the service entrance conductors are in cable
or conduit.
,◉ A multi-wire circuit has
A)
protection from circuit breakers, not fuses.
B)
a red and a black wire.
C)
two neutral wires.
D)
two ground wires.. Answer: The answer is A RED AND A BLACK
WIRE. A multi-wire circuit has a red and black wire.
◉ Service entrance (se) cable must be securely clamped to the house
A)
every 6 feet.
B)
every 30 inches, generally.
C)
using brass clamps and screws.
D)
,every 12 inches, using rustproof fasteners.. Answer: The answer is
EVERY 30 INCHES, GENERALLY. Service entrance cables should be
clamped to the house every 30 inches typically.
◉ Putting the fuses upstream of the disconnect switch in the service
box
A)
is a result of installing the box upside-down.
B)
may cause a short circuit through the fuses.
C)
is a result of connecting the service conductors to the line side,
rather than the load side.
D)
makes it dangerous to change the fuses even when the house power
is shut off.. Answer: The answer is MAKES IT DANGEROUS TO
CHANGE THE FUSES EVEN WHEN THE HOUSE POWER IS SHUT OFF.
Putting fuses upstream of the disconnected switch in the service box
makes it more dangerous to change the fuses. Even when the house
power is shut off, there will be power to the fuse terminals.
◉ Assuming copper, standard wire type, and normal temperature
rating, what is the typical conductor size (in awg) for a 200A service
in the U.S.?
, A)
3/0
B)
1/0
C)
2/0
D)
#2. Answer: The answer is 2/0. A 200 amp service must have 2/0
gauge wire in the U.S.
◉ All of these are common branch circuit problems except
A)
open splices.
B)
NMD wires run through floor joists without tubes or grommets.
C)
undersized wire.
D)
