Section410.29. Fixture Rating.
(a) All fixtures requiring ballasts or transformers
13 shall be plainly marked with their electrical rating and the
manufacturer's name, trademark, or other suitable means of
14 identification.
15 ........ - (b) The electrical rating shall include the voltage and
frequency, and shall indicate the current rating of the unit
. 16 including the ballast, transformer or auto-transformer.

19 Section 422.5 Amended
Z0 Section 422.5 is hereby amended to read as follows:
Section 422.5. Branch Circuit Ampacity. The provisions
of this section specify sizes of conductors capable of carrying
appliance current without overheating under the conditions specified
(see Article 210). They are not intended to appl~ to conductors
which form an integral part of the appliance.
(a) The branch circuit ampacity of an individual branch
circuit shall no= be less than the marked ampere rating of the
appliance or the marked ampacity rating of an appliance having
combined loads (see Section 422.32).
EXCEPTION NO. 1. For household cooking appliances,
see Table 220.5.
EXCEPTION NO. 2. For motor-operated appliances not
having a marked ampacity rating the branch circuit ampacity shall
be in accordance with Part B or Article 430.
30 EXCEPTION NO. 3. Except as noted in Section 210.23(b),
Exception No. 1, an appliance, other than a motor-operated
31 appliance, which is continuously loaded, the branch circuit ampacit5
shall not be less than 125 percent of the marked rating.
(b) For branch circuits supplying appliances and other
loads, theampacity rating shall be determined in accordance with
Section 210.24.
(c) In every dwelling unit !fixed' appliances, such as
food grinders, dishwashers, washing machines, dryers, laundry
tray locations, built-in refrigerators, built-in freezers, furnac~
air conditioners and buklt-in heaters, or any other fixed applian,
with motors 1/4 h.p. or larger shall be on a separate branchcircui.
supplied'by a minimum No. 12 AWG wire. Each dwelling. unit shall
have installed therein an individual food waste grinder branch
circuit. Said circuit shall be supplied withaminimum No. 12 AWG
wire and a 15 ampereindicating. type switch. Said switch shall be
located in the wall adjacent to the sink. Food waste grinder shall
be wired with a minimum of No. 16 AWG 3 wire SPT-3 thermoplastic
hard finish cord or equal and an approved grounding type cord grip
cap must be used. ~ '
Section 424.3 Amended
Section 424.3 ~s hereby amended.to read as follows:
Section 424.3. (a) Br~nch Circuit Requirements. Fixed
heating equipment shall be supplied by branch circuits rated. 15,
20, or 30 amperes. An individual branch circuit may supply any
load.
EXCEPTION: Fixed infra'red heating. equipment may be
supplied from branch circuits rated not more than 50 amperes as
provided in Section 424.23.
(b) Branch Circuit Sizing. Fixed space heating equip-
ment shall be considered as a continuous load for sizing branch
circuits.
The ampacity of branch circuit conductors supplying fixed
space heating equipment consisting of resistance elements with or
without a motor shall be calculated on the basis of 125 percent of
the total load of the motors and the heaters.
The ampacity of the branch circuit conductors supplying
fixed space heating equipment consisting of mechanical refrlgeratio~
-withor without res. istance units shall be calculated as provided= for
in Section 430.25.
Approved recessed ceiling heaters using not more than
250 watts infra-red lamp may be installed on a lighting branch
circuit by reducing the allowable number of lighting outlets by
two 'for each single 'lamp device used However, not more than two
such devices shall be connected to any one lighting branch circuit.
Any number of multiple lamp and single lamp heaters, the total
wattage not exceeding 1500 watts or the total number of 250 watt
.lamps not exceeding six, may be connected to a separate 20 ampere
branch circuit.
'
Section 512.4 Added
Section 512.4 is added to read as follows:
Section 512.4. General. Garages or carports accessory
to dwelling units shallbe wired with a minimum of one switched
light outlet, and one receptacle per each two auto statls. ISaid
wiring, if exposed, shall be in approved metal raceways. ,All
wiring to detached accessory buildings shall be run'underground.
I EXCEPTION: In garages or carports accessory to Group H
Occupancy, receptacles may be omitted.
Section 600.1 Amended
Section 600.1 is hereby amended to read as follows:
4
Section 600.1. Scope. The provisions of this section
5 shall apply to the'installation of conductors and equipment for
electric signs and outline lighting as defined in Section 100. A
5 sign circuit shall be provided and installed to an accessible
location at the front'of all commercial and store buildings
V - ·
Section 600.2 Amended
8
Section 600.2 is hereby amended to read as follows:
Section 600.2. Disconnect Required. Each outline
10 lighting installation and each sign of other than the portable
type shall be controlled by an externally operable switch or
11 breaker which will open all ungrounded conductors and shall
1~be suitable for conditions' of installation, such as exposure
to the .weather.
13 ]a) In Sight of Sign. An accessible disconnecting
means consisting of one or more Type S plug fuses, or a suitable
14 switch, shall be installed in or on each fixed sign and in or on
a transformer enclosure of each electric discharge outline lighting
15 system to provide means for disconnecting all ungrounded conductors
--- supplying such equipment ' '
16 '
(b) Control Switch Rating. Switches, flashers, and
17 similar devices controlling ransformers shall be either of a type
approved for the purpose, or have a current rating not less than
18 twice the current rating of the transformers. On alternating-
current circuits, general use alternating-current snap switches
19 may be used to control inductive loads other than motors, not.
exceeding the ampere rating of switch. See Section 380.14.
