sEeTl ;ro, 8156.2 GENERAL LIGHTING FOR GENERAL ILLUMINATION. In the oc-
cupancies listed inthe Table in Section 8156.5, a load
of not less than the unit load of Column "A" shall be included for each
square foot of floor area. In determining the -load on the "Watts per
square foot" basis, the floor area shall be computed from the outside
dimensions of the building, apartment, or area involved, and the number
of floors, not including open porches, garages, in connection with
dwelling occupancies, nor unfinished spaces in basements or attics of
dwellings. All convenience outlets of 20 ampere or less rating in sin-
gle family and multi -family dwellings and in guest rooms of hotels, ex-
cept those connected to the appliance circuits specified, may be consid-
ered as outlets for general illumination. (No additional load need be
included for such outlets).
;E,eTi 8156.3 OTHER LOADS. For lighting other than general illumi-
nation and for appliances other than motors, a load
of not less than the unit load specified below shall be included for
each outlet.
Outlets supplying ::specific appliances
and other loads ........................Amp rating of appliances
Outlets supplying heavy duty lamp holders ............ :.... 5 Amps
**Other outlets..........................................1.1-.z Amps
**NOTE: This provision not applicable to receptacle outlets
provided for the connection of fixed lighting units to
facilitate servicing and replacement.
L
5^s=rr-'r44&N 8156.4 EXCEPTIONS: The minimum loads for outlets (paragraph
8156.3) shall be Cllodificd as follows:
1. Ranges - For household electric ranges, the branch circuit load may
be computed in accordance with Section 220.2.
2. Show Window Lighting - For show window lighting, a load of not less
than 200 watts per linear foot of show window, measured horizontally
• along its base, may be allowed in lieu of specified load per outlet.
3. Multi -Outlet Assemblies - Where fixed multi -outlet assemblies are
employed, each five feet or fraction thereof of each separate and
continuous length shall be considered as one outlet of not less
than 1 1/2 ampere capacity; except in locations where a number of
appliances are likely to be used simultaneously, when each one foot
or fraction thereof shall be considered as one outlet of not less
than 1 1/2 ampere.

fied in Section 8156.3 and the computed branch circuit
load for receptacle outlets in other than dwelling occupancies for which
the allowance is not more than 1 1/2 amperes per outlet, may be included
with the general lighting load and subject to the demand factors in Sec-
tion 8156.5.
Stir-eN 8156.7 DWELLING OCCUPANCIES. In single-family dwellings, in

cluded for small appliances (portable appliances supplied from recep-
tacles of 20 ampere or less rating), in dining room, kitchen, and laun-
dry. If the load is subdivided through two or more feeders, the com-
puted load for each shall include not less than 3,000 watts for small
appliances. In no case shall the feeder be smaller than No. 8 AWG wire.
