Advantages of Steel City®Boxes & Covers
Notched Ears on
Switch Boxes
•Steel City®Switch Boxes feature
a longer ear and a special notch.
This provides clearance for the
screws that are used to attach
wall plates to GFCI or rocker-type
light switches
Raised Ground Screw Bump
in 4" Square, 411⁄16" and
Utility Boxes
•Quicker surface mounting by
eliminating the need to remove the
portion of the screw that threads
through the back of the box
•Allows for improved repositioning of
grounding conductor
•Ground bump standard in 21⁄8" boxes
•Ground bump optional in 11⁄2" boxes
“MS” Bracket Boxes
•Mounts without the use of screws
•Mounts to the open or closed side
of the stud
•Works on stud depths up to 4" Pre-Installed Screws are
Packaged in Raised
Position
•Eliminates extra step of having to
back out the screw during cover
installation
Steel City®switch and outlet boxes are protected from rust and corrosion by
zinc-galvanizing. All clamps and other component parts are electrogalvanized
separately, before assembly in the box, to ensure corrosion protection of
every surface. Steel City®galvanized finish meets the requirements of
Underwriters Laboratories, Inc. and Federal Specifications.
Eccentric Knockouts
on Square Boxes
•Provide better contact with
conduit fitting and locknut to the
box, improves grounding path,
stronger than 3⁄4" knockout
•Available in all four standard size
square boxes
•Improved 3⁄4" knockout position on square boxes
•Less labor required to install 3⁄4" conduit to box

Overview
Guide to Steel City Knockouts, Pryouts, Ears, Brackets and Clamps
Knockouts and Pry outs
Steel City conduit KOs have standard trade size dimensions. KOs are uniform and true for
attachment of cable or conduit connectors. Pryouts for cable entrance are slotted — a twist with
a screwdriver removes them. KOs and Pryouts are precision stamped to permit easy removal, but
remain sufficiently strong and sturdy when not removed.
Outlet Box Ears
Mounting ears support the box independent of the electrical system
attachments. Switch boxes have a fixed ear for old work installations.
Ears for plaster are set 1⁄16" forward of the box face in position for old
work (modernization) except where specifically noted.
Tapped Holes for Grounding
All Steel City boxes have a 10-32 tapped hole in the bottom of the
box for attaching separate ground wire.

Article 314 of the National Electrical Code covers the installation and use
of boxes. The article includes table references that guide the electrician
in the selection of the proper box size necessary to safely accommodate
electrical service requirements. The box capacity table shown below is
reproduced in part from the NEC as a quick reference and guide. The
NEC should be consulted for complete details.
NEC Reference
(b) Other Boxes.
Boxes 100 cubic inches or less, other than those described in Table
314.16(A), conduit bodies having provisions for more than two conduit
entries and non-metallic boxes shall be durably and legibly marked by the
manufacturer with their cubic inch capacity. The maximum number of
conductors permitted shall be computed using the volume per conductor
listed in Table 314.16(A), with the deductions provided for in Section
314.16(B), and these volume deductions shall be based on the largest
conductor entering the box. Boxes described in Table 314.16(A) that have a
larger cubic inch capacity than is designated in the table shall be permitted
to have their cubic inch capacity marked as required by this section and the
maximum number of conductors permitted shall be computed using the
volume per conductor listed in Table 314.16(B).
(c) Conduit Bodies.
Conduit bodies enclosing 6AWG conductors or smaller other than short-
radius conduit bodies as described in 314.5, shall have a cross-sectional
area not less than twice the cross-sectional area of the largest conduit to
which they can be attached. The maximum number of conductors permitted
shall be the maximum number permitted by Table I, Chapter 9, for the
conduit to which it is attached.
Conduit bodies that are durably and legibly marked by a manufacturer with
their volume shall be permitted to contain splices, taps or devices. The
maximum number of conductors shall be calculated in accordance with
314.16(B) and are supported in a rigid and secure manner.
Article 314 — Boxes and Fittings
314.16. Number of Conductors in Outlet, Device and Junction
Boxes, and Conduit Bodies.
Boxes shall be of sufficient size to provide free space for all conductors
enclosed in the box.
The provisions of this section shall not apply to terminal housings supplied
with motors or generators. (See Section 430.12.)
Boxes and conduit bodies containing conductors, size No. 4 or larger, shall
also comply with the provisions of Section 314.28.
(a) Standard Boxes.
The maximum number of conductors permitted in standard boxes are listed
in Table 314.16(A) reproduced in part on page A6. See Article 314.28(A)
through (D) where boxes or conduit bodies are used as junction or pull boxes.
(1) Table 314.16(A) shall apply where no fittings or devices, such as fixture
studs, cable clamps, hickeys, switches, or receptacles, are contained in
the box and where no grounding conductors are part of the wiring within
the box. Where one or more of these types of fittings, such as fixture
studs, cable clamps, or hickeys are contained in the box, the number of
conductors shown in the table must be reduced by one for each type of
fitting; an additional deduction of one conductor must be made for each
strap containing one or more devices; and a further deduction of one
conductor shall be made for one or more grounding conductors entering
the box. Where a second set of equipment grounding conductors, as
permitted by Section 250.146(D), is present in the box, then an additional
deduction of one conductor must be made. A conductor running through
the box is counted as one conductor, and each conductor originating
outside of the box and terminating inside the box is counted as one
conductor. Conductors, no part of which leaves the box, shall not be
counted. The volume of a wiring enclosure (box) shall be the total volume
of the assembled sections, and, where used, the space provided by
plaster rings, domed covers, extension rings, etc., that are marked with
their volume in cubic inches, or are made from boxes the dimensions of
which are listed in Table 314.16(A).
(2) For combinations of conductor sizes shown in Table 314.16(A), the
maximum number of conductors permitted is computed using the volume
per conductor listed in Table 314.16(B) with the deductions provided for
in Section 314.16(B) and these volume deductions shall be based on the
largest conductor entering the box. The maximum number and size of
conductors listed in Table 314.16(A) must not be exceeded.

Finally a quick, easy solution for a
common rough-in problem!
Steel City®Adjustable
Mud Ring
Now there’s a quick, easy and economical way to ensure that stud-mounted outlet boxes fit
flush with finished drywall, plaster or ceramic tile. The Steel City®Adjustable Mud Ring
features an inner ring that adjusts from 1⁄2" to 11⁄2" in depth to accommodate various drywall
thicknesses. Marked with a measured rule and equipped with two adjustment screws, the
inner ring can be set to the anticipated depth prior to installation and then easily adjusted
after drywall installation to accommodate any variation in depth (1⁄2to 11⁄2). Rely on the Steel
City®Adjustable Mud Ring for a code-compliant finish in many applications.
