✔✔When conductors are installed in a conduit or tubing nipple of _____ or less in
length, the ampacity adjustment factors for more than three (3) current-carrying
conductors in the raceway, are not required to be applied. - ✔✔24 inches
adjustment factors for more than three (3) current-carrying conductors in raceways shall
not apply where the raceway is not more than 24 inches in length. Where more than 3
current-carrying conductors are installed in short lengths of conduit or tubing, the
heating effect caused from the additional conductors is insignificant therefore, the
allowable ampacity of the conductors is not greatly reduced.
✔✔In compliance with the NEC, the total marked rating of a 120-volt, cord-and-plug-
connected room air conditioner shall not exceed _____ of the rating of a branch circuit
when lighting units, general-use receptacles, or other appliances are supplied from the
branch circuit. - ✔✔50%
the special provisions for room air conditioners which are (1) rated not over 250-volts
ac, single-phase and (2) which are cord-and-attachment plug connected. In order to
prevent overloading the branch circuit, as per Section 40.62(C), the total rating of the
A/C unit shall not exceed 50% of the rating of a branch circuit where lighting units,
general-use receptacles or appliances are also supplied.
✔✔What shall not be located over the steps of a stairway? - ✔✔overcurrent devices
"overcurrent devices shall not be located over steps of a stairway." This requirement
address a serious safety issue. No one should be required to stand on different treads
on a stairway to replace, repair, maintain, install, troubleshoot, or reset overcurrent
devices in a panelboard or switchboard located in a stairway.
, ✔✔Where a permanently installed outdoor swimming pool is located on residential or
commercial properties, at least one (1) single-phase, 125-volt, 15- or 20-ampere
receptacle shall be located not less than _____ from and not more than _____ from the
inside wall of the swimming pool. - ✔✔6 feet - 20 feet
apply to the installation of wiring methods and equipment in or adjacent to permanently
installed swimming pools.
each permanently installed swimming pool is to be provided with at least one (1) single-
phase, 15- or 20-ampere, 125-volt, receptacle placed not closer than six (6) feet from
the pool and not more than twenty (20) feet from the pool.
This requirement allows ordinary appliances such as a radio, to be safely plugged in
and used near the pool, but avoids the need for extension cords in the pool vicinity. Be
advised the receptacles must be provided with
✔✔Metal water pipes installed in or attached to a building or structure shall be bonded
to _____.
a. the service equipment enclosure
b. the grounded conductor at the service
c. the grounding electrode conductor
d. any of the above - ✔✔Any of the above
requires metal water piping systems to be bonded to any of (1) the service entrance
enclosure, (2) the grounded conductor at the service, (3) the grounding electrode
conductor.Where mechanical and electrical connections are within equipment, a failure
of electrical insulation can result in the connected piping systems becoming energized.
For example, an insulation failure in an electrical circuit of a water heater could energize
the metal water piping.Metal water piping systems must be bonded so that when a fault
occurs between an ungrounded (hot) conductor and the piping, the potential difference
between the two is minimized, thereby reducing the risk of electrical shock.Also, note
where installed in or attached to a building or structure, all metal piping systems,
including gas piping, that is likely to become energized shall be bonded to a grounded
source.
✔✔When armored cable, Type AC, is installed in an accessible attic and is run parallel
to the sides of rafters, studs, or floor joists, _____.
a. the cable shall be protected with running boards
b. the cable shall be protected by guard strips at least as high as the cable
c. either A or B
d. neither guard strips nor running boards shall be required - ✔✔neither guard strips nor
running boards shall be required
