air conditioners.
A distribution panelboard shall be rated not less than
50 amperes and employ a 2-pole circuit breaker rated
40 amperes for a 40-ampere supply cord, or 50
amperes for a 50-ampere supply cord. A distribution
panelboard employing a disconnect switch and fuses
shall be rated 60 amperes and shall employ a single 2-
pole, 60-ampere fuseholder with 40- or 50-ampere
main fuses for 40- or 50-ampere supply cords,
respectively. The outside of the distribution panelboard
shall be plainly marked with the fuse size.
The distribution panelboard shall be located in an accessible location but shall not be located in a bathroom or a clothes closet. A clear working space at least 750 mm (30 in.) wide and 750 mm (30 in.) in front of the distribution panelboard shall be provided. This space shall extend from the floor to the top of the distribution panelboard.

(B) Branch-Circuit Protective Equipment. Branch- circuit distribution equipment shall be installed in each mobile home and shall include overcurrent protection for each branch circuit consisting of either circuit breakers or fuses.

The branch-circuit overcurrent devices shall be rated as follows:

(1) Not more than the circuit conductors; and

(2) Not more than 150 percent of the rating of a single appliance rated 13.3 amperes or more that is supplied by an individual branch circuit; but

(3) Not more than the overcurrent protection size and of the type marked on the air conditioner or other motor-operated appliance.

(C) Two-Pole Circuit Breakers. Where circuit breakers are provided for branch-circuit protection, 240-volt circuits shall be protected by a 2-pole common or companion trip, or by circuit breakers with identified handle ties.

(D) Electrical Nameplates. A metal nameplate on the outside adjacent to the feeder assembly entrance shall read as follows:

THIS CONNECTION FOR 120/240-VOLT,
3-POLE, 4-WIRE, 60-HERTZ,

AMPERE SUPPLY

The correct ampere rating shall be marked in the blank space.

Exception: For manufactured homes, the manufacturer shall provide in its written installation instructions or in the data plate the minimum ampere rating of the feeder assembly or, where provided, the service-entrance conductors intended for connection to the manufactured home. The rating provided shall not be less than the minimum load calculated in accordance with 550.18.

550.12 Branch Circuits. The number of branch circuits required shall be determined in accordance with

550.12(A) through (E).
(A) Lighting. The number of branch circuits shall be based on 33 volt-amperes/m 2 (3 VA/ft 2) times outside di mensions of the mobile home (coupler excluded) divided by 120 volts to determine the number of 15- or
20-ampere lighting area circuits, for example,
3 x length x width
120 x 15 (or 20)
= No. of 15— (or 20-) ampere circuits

(B) Small Appliances. In kitchens, pantries, dining rooms, and breakfast rooms, two or more 20-ampere small appliance circuits, in addition to the number of circuits required elsewhere in this section, shall be provided for all receptacle outlets required by

550.13(D) in these rooms.Such circuits shall have no other outlets.

Exception No. 1: Receptacle outlets installed solely for the electrical supply and support of
