In working with an electrical engineer on a project, what
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-
information would the designer most likely put on the interior
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-
design power plan?
i,- i,-
A. dedicated outlets
i,- i,-
B. conduit sizing
i,- i,-
C. speaker locations
i,- i,-
D. switch locations
i,- i,- i,-i,- i,- D. switch locations
i,- i,-
Because the interior designer coordinates switch locations with
i,- i,- i,- i,- i,- i,- i,- i,-
furniture placement, they are the best answer. The interior
i,- i,- i,- i,- i,- i,- i,- i,- i,-
designer would not determine conduit size or dedicated outlets.
i,- i,- i,- i,- i,- i,- i,- i,- i,-
Speaker locations would be shown on the reflected ceiling plan.
i,- i,- i,- i,- i,- i,- i,- i,- i,-
Who would be LEAST involved in the section of an underfloor
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-
raceway system? i,-
A. structural engineer
i,- i,-
,B. electrical consultant
i,- i,-
C. mechanical consultant
i,- i,-
D. architect
i,- i,-i,- i,- C. mechanical consultant
i,- i,-
An underfloor raceway system uses metal enclosures buried in
i,- i,- i,- i,- i,- i,- i,- i,- i,-
the concrete floor slab. The selection would obviously involve the
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-
electrical consultant and the architect because this is part of the
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-
architectural work. The structural engineer would also be involved
i,- i,- i,- i,- i,- i,- i,- i,- i,-
because the size, spacing, and configuration of the system affects
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-
the thickness of the slab and its reinforcing.
i,- i,- i,- i,- i,- i,- i,-
What activates the sprinkler heads?
i,- i,- i,- i,-
A. fire
i,-
B. building security system
i,- i,- i,-
C. heat
i,-
D. smoke
i,- i,-i,- i,- C. heat i,-
Each individual sprinkler head has a heat sensitive element. When
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-
heat is above a certain threshold, this activates the sprinkler.
i,- i,- i,- i,- i,- i,- i,- i,- i,-
What would NOT be allowed in an access floor with removable
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-
panel?
A. plumbing
i,-
,B. HVAC
i,-
C. electrical conduit
i,- i,-
D. computer cable
i,- i,- i,-i,- i,- A. plumbing i,-
Computer cable and electrical conduit are commonly placed in
i,- i,- i,- i,- i,- i,- i,- i,- i,-
raised access floors, used below computer rooms or where
i,- i,- i,- i,- i,- i,- i,- i,- i,-
equipment must be kept cool. Duct work is also allowed.
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-
Plumbing is not allowed because pipe breaks can cause problems.
i,- i,- i,- i,- i,- i,- i,- i,- i,-
What determines the depth of steel studs in commercial
i,- i,- i,- i,- i,- i,- i,- i,- i,-
construction?
A. acoustical rating of the wall
i,- i,- i,- i,- i,-
B. the fire rating of the wall
i,- i,- i,- i,- i,- i,-
C. the thickness of the gypsum board
i,- i,- i,- i,- i,- i,-
D. partition height, gauge of the stud, spacing of studs and
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-
number of layers of gypsum board
i,- D. partition height, gauge
i,- i,- i,- i,- i,-i,- i,- i,- i,- i,- i,-
of the stud, spacing of studs and number of layers of gypsum
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-
board
The most common size of 2 1⁄2′′ for nonstructural steel framing.
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-
This depth is sufficient for normal ceiling heights and slab to slab
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-
partitions. It allows enough room for electrical boxes and small
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-
pipes. The studs are normally placed 16′′ or 24′′ on center.
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-
, Where is the junction box for a power pole located?
i,- i,- i,- i,- i,- i,- i,- i,- i,-
A. access panel
i,- i,-
B. floor
i,-
C. plenum
i,-
D. circuit breaker box
i,- i,- i,- i,-i,- i,- C. plenum
i,-
Commercial construction includes a plenum space above finishedi,- i,- i,- i,- i,- i,- i,- i,-
ceiling for mechanical systems, wiring and other building services.
i,- i,- i,- i,- i,- i,- i,- i,- i,-
A J-box for branching or connecting electrical circuits would be
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-
within the plenum space. Wiring is concealed within a conduit. J-
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-
boxes will be exposed or mounted on the wall or finished ceiling
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-
for lighting or other features requiring an electrical connection.
i,- i,- i,- i,- i,- i,- i,- i,-
Where would it be best to call out the frame material on an entry
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-
door?
A. door schedule
