disconnecting manner, it's far authorised to ground the meter enclosure to the _____
conductor at the load facet of the service disconnect if floor-fault safety is not supplied. -
ANS-Grounded
, The meter enclosure to be grounded by using connection on the load aspect of the carrier
disconnect where (1) no ground-fault protection is installed, (2) the meter enclosure is

For residing units, GFCI protection is required for all unmarried-segment, one hundred
twenty five-volt, 15- and 20-ampere receptacles set up inside six (6) ft of the top internal
edge of the bowl of sinks positioned in _____.
A. Laundry rooms
b. Bathrooms
c. Garages
d. All of those regions - ANS-All of these areas
irrespective of what the location or room in a dwelling, where the 15- or 20-ampere, 125-volt
eceptacles are established inside six (6) feet from the pinnacle inner edge of the bowl of the
sink, GFCI safety ought to be furnished to prevent a ground-fault surprise chance.

Generally, in a movie theater the guide switch for controlling the emergency lighting systems
is permitted to be located _____. - ANS-in an on hand region inside the lobby
observe buildings used as a theater or for a similar cause. Section 520.8 mandates the
manipulate of emergency systems in theaters to conform with the policies set forth in Article
seven hundred; Part V of Article seven hundred applies to the control of emergency lighting
fixtures circuits. Section seven-hundred.21 does no longer allow a manual control switch for
emergency lights to be located in a motion image projection sales space or on a level or
platform; the switch will be located inside the foyer or at a handy handy place.Emergency
lighting systems are designed and established to hold a particular diploma of illumination for
method of egress of the building within the occasion of fire, or comparable emergency, or if
the regular power deliver fails.
Given: A one-circle of relatives residing unit with a call for load of 200 amperes is provided
with a 120/240 volt, single-section, electrical system from the neighborhood utility business
enterprise. What is the MINIMUM size aluminum THW conductors required for use as
service-front conductors for this house? - ANS-four/zero AWG
one-circle of relatives residing 120/240 volt, single-phase, provider-front conductors to be
sized at an ampacity of no longer less than 83% of the service rating. Therefore, two
hundred amperes x 83% = 166 amperes; length 4/0 AWG THW aluminum conductors with
an allowable ampacity of a hundred and eighty amperes must be decided on for this living.
