30 AMPERE SUPPLY
or
THIS CONNECTION IS FOR 208Y/120-VOLT OR 120/240-VOLT AC, 3-POLE, 4-WIRE,
60 HZ AMPERE SUPPLY.
The correct ampere rating shall be marked in the blank space.

(E) Location. The point of entrance of a power-supply assembly shall be located within 4.5 m (15 ft) of the

overcurrent protective device not exceeding the power- supply assembly rating shall be provided where more than two branch circuits are employed.

552.46 Branch Circuits. Branch circuits shall be deter- mined in accordance with 552.46(A) and (B).

(A) Two to Five 15- or 20-Ampere Circuits. Two to five

15- or 20-ampere circuits to supply lights, receptacle
out lets, and fixed appliances shall be permitted. Such
park trailers shall be equipped with a distribution panel
board rated at 120 volts maximum with a 30-ampere
rated main power supply assembly. Not more than two
120-volt thermostatically controlled appliances (e.g., air
conditioner and water heater) shall be installed in such
systems unless appliance isolation switching, energy
management systems, or similar methods are used.

Exception: Additional 15- or 20-ampere circuits shall be permitted where a listed energy management system rated at 30 amperes maximum is employed within the system.

(B) More Than Five Circuits. Where more than five cir cuits are needed, they shall be determined in accordance with 552.46(B)(1), (B)(2), and (B)(3).

Exception: A park trailer shall be permitted to have the electrical point of entrance located more than 4.5 m (15 ft) from the rear. Where this occurs, the distance beyond the 4.5-m (15-ft) dimension shall be added to the cord's minimum length as specified in 551.46(B).

552.45 Distribution Panelboard.

(A) Listed and Appropriately Rated. A listed and appro- priately rated distribution panelboard shall be used. The grounded conductor termination bar shall be insulated

(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. ofl5- (or 20 -) ampere circuits

The lighting circuits shall be permitted to serve built- in gas ovens with electric service only for lights, clocks or timers, or listed cord-connected garbage disposal
from the enclosure as provided in
552.55(C). An

equipment grounding terminal bar shall be attached
inside the metal enclosure of the panelboard.

(2) Small Appliances.

Small-appliance branch circuits

Location. The distribution panelboard shall be installed

in a readily accessible location. Working clearance for
the panelboard shall be not less than 600 mm (24 in.)
wide and 750 mm (30 in.) deep.
shall be installed in accordance with 210.11(C)(1).

(3) General Appliances, (including furnace, water heater, space heater, range, and central or room air conditioner, etc.) An individual branch circuit shall be

permitted to supply any load for which it is rated. There shall be one or more circuits of adequate
