x-ray departments.
10. Schools and classrooms shall be wired for not
less than 2 watts per square foot.
11. Storage warehouses shall be wired for not less
than 1/4 watt per square foot.

cuit. Such transformers shall not be considered as

(p) Computation of Load Currents. Current carry-
ing capacity for various vols sRa ITe computed as
follows: Line voltage between 100 and 125 volts shall

4 -wire systems shall be computed as 120/208 volts.
(q) computation of Loads. The computation of

WIRING DETAILS
SECTION 17(a) Cutouts shall be installed in
approved cabinets, panel boards, etc. in such manner that
no live parts are exposed to accidental contact. Provided,
however, that this shall not apply to cutouts installed
on switchboards under competent supervision.
(b) No wood moulding or cheat work shall be
installed.
(c) In partitions with studs less than two and
one-half inches in width, wires shall be encased in
armored cable, flexible nonmetallic tubing, or approved
ducts.
(d) Outlet boxes and pull boxes shall be of such
size as to accomodate with ease all wires and devices
installed therein.
(e) In closets, the lighting outlet shall be
placed on the wall over the door or may be located on
the ceiling if operated by a wall switch, door switch
or ceiling pull switch. Drop cords shall not be installed
in closets.
(f) Where two or
switches are grouped each
marked, indicating what it
more feeders or sub -feeder
switch shall be permanently
controls.
FIXTURE DETAILS
SECTION 18(a) Grounded Locations. Each outlet
for fixtures located within reac et horizontally
or eight feet vertically of conducting floors or other
conducting objects shall be controlled by wall switches,
by ceiling pull switches with insulated chain or cord,
or by pendant switches constructed of porcelain or other
suitable insulating material. All insulators in chain
pulls shall be placed not more than one inch from socket
or fixtures. Key sockets and brass shell pendant switches
will be permitted in such locations if the shells are
permanently and effectively grounded.
(b) Drop Cord. Drop cord, unless of an approved
portable type, sFa=e used only where it hangs free
in the air, shall not be used for the support of more
than one socket with its reflector equipment, and shall
not be used for the support of sockets fitted with en-
closing globes or bowls.
HEATING & COOKING APPLIANCES
SECTION lg(a) General. Portable heating appli-
ances shall not be used on any circuits operating at more
than 300 volts between conductors. Heating appliances
which have bare elements or other bare current carrying
parts exposed to accidental contact shall not be used
on any circuit operating at more than 150 volts to ground.
Any heating appliance in a dwelling, rated at
more than 1650 watts shall be wired for not less than
200 volts. Where the voltage to ground exceeds 150 volts
the conductors to such heating appliance shall be installed
in a metal protected system. If such heating appliance
Is portable the receptacle shall be of suitable capacity.
(b5 Three -wire Circuits. In dwellings and apart-
ment houses 'or or morxe a
e iir heating appliances, rated
at not less than 1650 watts each, and operating at not less
than 200 volts, may be installed on a heavy duty branch
heater circuit, protected by a single set of overload
protective devices provided the total connected load does
not exceed 35 amperes per conductor. Heavy duty branch
heater circuits may be two -wire derived from either a
110-220 volt single phase source, or a 220 volt three-
phase source; or they may be three-phase, three -wire
derived from a three-phase 220 volt source. The tap from
such circuit to the heating appliance shall in no case be
less than No. 12 A.W. gauge wire nor over eighteen (181f)
inches in length. All ungrounded conductors shall be
switched at each heating appliance.
This subsection shall not be construed to permit
heaters for different apartments being connected to the
same circuit.
(c) Demand Factors. Demand factors may be applied
to reduce the -size o s�` ervTces, feeders, and subfeeders
in dwellings and apartment houses supplying the following
types of load: Water heaters, space heaters and air con-
ditioning devices of 1650 watts or over as follows:

houses supplying the following types of load: the values
in the table below apply to one or more cooking and bak-
ing appliances in dwellings or apartment houses but are
not applicable to other appliances.
Column I
For an electric range exceeding 12 K.W. but not
exceeding 16 K.W. a 70% demand factor may be applied to
branch circuit. For an electric range exceeding 16 K.W.
but not exceeding 21 K.W. a 60% demand factor may be
applied to branch circuit. Unless statements are filed
in writing from the owner or authorized agent stating
capacity of range each range shall be figured at not less

branch circuit. For an electric range exceeding 16 K.W.
but not exceeding 21 K.W. a 60% demand factor may be
applied to branch circuit. Unless statements are filed
in writing from the owner or authorized agent stating

SECTION 20. Location of Branch Circuit Protect-
ive Devices. Branch circurcu—proE_ec iTcrve devices shaall F —
insta�3ed Tn and for each occupancy or in a location which
is accessible to occupants at all times. Nothing con-
tained in this Code shall be deemed or construed to permit
the installation of any electrical device, outlet or cir-
cuit in any occupancy, the control of or the protection
of which is not accessible to the occupant at all times.
No part of any circuit shall supply electrical

Laboratories, Inc. label or other recognized testing lab-
oratory label.
