GRADE
bBonding jumpers on the supply side of the service are sized according to NEC® Table ___. -
250.102(C)(1)
Section 250.96(B) permits equipment to be ___ in order to minimize electromagnetic interference (often
called "noise"). - isolated
The size of bonding jumpers on the line or supply side of service equipment is based on the size of the
___. - supply conductor
Section 250.90 requires that an equipment bonding jumper be sized to carry the circuit current that it
must carry during normal circuit operation. - False
Refer to Figure 307.32. If you are to size the bonding jumpers from the conduits in Section 1 to the
equipment grounding busbar, you would use NEC® Section ___ to determine the minimum size of the
BJs. - 250.102(C)
The conductors at Point B in Figure 307.53 are on the ___ side of the service equipment. - load
Metal raceways enclosing GECs are considered to be on the ___ of the service equipment. - line
A branch circuit is installed using metal conduit that will serve as the EGC. A separate EGC was not pulled
in with the circuit conductors. However, a short section of flexible nonmetallic conduit was used in the
middle of the run. When a bonding jumper is installed around the short section of flexible nonmetallic
conduit, the jumper is in ___ with the EGC (metal conduit). - series
Which of the following Code Sections requires the non-current-carrying metal parts of the service
equipment to be bonded together? - 250.92(A)
, The Article 100 definition of bonding emphasizes ___. - electrical continuity
Which of the following tables is used to select a supply-side equipment bonding jumper? - Table
250.102(C)(1)
When grounding electrode conductors are installed in metal conduit for physical protection, the conduit
must be ___. - both a and b
Refer to Figure 205.17. The minimum size bonding jumper for each FMC between the transformer and
Panel LK is ___ AWG. - 2
The MAIN in the switchgear shown in Figure 307.32 is rated at 1600 amps and each conduit contains 600
kcmil conductors. The minimum size of each of the BJs shown in Section 1 is ___ AWG or kcmil. - 1/0
A 120/208-volt switchgear is shown in Figure 307.32. The 1000-amp main is fed with parallel sets of 300
kcmil THHN/THWN aluminum conductors. The minimum size of each of the copper conductors
connected between the ground bar and each service pipe is ___ AWG. - 2
What Code reference requires CATV ground rods to be connected to the building service ground rod, as
one method of tying the two systems together? - 820.93
In general, bonding requirements for the supply (line) side of the service equipment are ___ bonding
requirements on the load side. - more stringent than
Section 250.97 requires a bonding jumper to be used to provide continuity around knockouts, except
where the largest knockout is used or the enclosure is listed for use without bonding. This applies for
circuits of which of the following voltage systems?
I. 120/240 V, 1Ø, 3-W II. 208Y/120 V, 3Ø, 4-W III. 480Y/277 V, 3Ø, 4-W - III only
A 600-amp, 120/240-volt, 3Ø, 4-wire service is to be installed in two conduits. The service-entrance
conductors installed are 350 kcmil. The two threaded RMC conduits enter the bottom of the CT can
where a hole saw was used to cut the holes. The hole saw "walked" a bit and wallowed out the holes so
that now you will have to install bonding bushings on the conduits.
