Conductors with _____ marked on the insulation are NOT approved for use in a wet
location. - ANSWER ✅✅✅✅THHN
conductors with THHN insulation are approved for use in dry and damp locations only
and conductors with THWN, THHW, and THW insulation are recognized for use in dry
and wet locations.
Given: A one-family dwelling unit with a demand load of 200 amperes is supplied with a
120/240 volt, single-phase, electrical system from the local utility company. What is the
MINIMUM size aluminum THW conductors required for use as service-entrance
conductors for this residence? - ANSWER ✅✅✅✅4/0 AWG
one-family dwelling 120/240 volt, single-phase, service-entrance conductors to be sized
at an ampacity of not less than 83% of the service rating. Therefore, 200 amperes x
83% = 166 amperes; size 4/0 AWG THW aluminum conductors with an allowable
ampacity of 180 amperes should be selected for this dwelling.
Where a 150 kVA, single-phase transformer having a secondary voltage of 120/240 is
installed at a multi-family dwelling, the full-load current rating, in amperes, of the
secondary is _____. - ANSWER ✅✅✅✅625 amperes
, To find the full-load current rating of the single-phase transformer apply the single-
phase current formula as shown:I = (150 kVA x 1000) / 240 volts = 15,000/240 = 625
amperes
Which one of the following listed circuit breakers is NOT a standard ampere rating? -
ANSWER ✅✅✅✅75 amperes
the standard ampere ratings for fuses and circuit breakers. A circuit breaker with an
ampere rating of 75 amperes is not a standard ampere rating.
The MINIMUM length of free conductor to be left at each junction box for the purpose of
splicing conductors, or making connections to illuminares or devices shall be _____ . -
ANSWER ✅✅✅✅6 inches
free conductor is to be left at each junction box for splices or the connection of
luminaires or devices. The intent of this rule is to ensure enough conductor slack for the
terminal connections or splices to be made easily.
In general, overhead service-drop conductors shall NOT be smaller than _____. -
ANSWER ✅✅✅✅8 AWG copper
overhead service-drop conductors to be not smaller than 8 AWG copper or 6 AWG
aluminum or copper-clad aluminum. Do not get service-drop conductors, the overhead
conductors between the utility electric supply system and the service point, confused
with the service-entrance conductors, the conductors from the service point from the
utility company to the service disconnecting means.
When a galvanized eye-bolt is to be used as the point of attachment for an electrical
service, the NEC requires the eye-bolt to be installed NOT less than _____ above
finished grade. - ANSWER ✅✅✅✅10 ft.
provide adequate vertical clearance of the conductors and prevent physical damage to
the conductors and prevent persons from making accidental contact with the conductors
which may create a shock hazard or electrocution. In no case shall the point of
attachment of the service-drop conductors to be less than 10 ft. above finished grade.
Why is electrical continuity required for metallic conduit? - ANSWER ✅✅✅✅To
establish an effective ground-fault path and facilitate the operation of the over-current
protective device.
Electrical continuity is required for metallic conduit to establish an effective ground-fault
path and facilitate the operation of the overcurrent protective device.
In dwelling units, receptacle outlets installed for countertop surfaces, must be located
above, but NOT more than _____ above the countertop or work surface. - ANSWER
✅✅✅✅20 inches
