Overcurrent Protection
Manually resettable over current devices shall be installed to protect the line voltage electrical system
components.
Power Source Protection
A main over current protection device shall be provided that is either incorporated in the power source or
connected to the power source by a power supply assembly.
The size of the main over current protection device shall not exceed 100 percent of the rated amperage stated on
the power source specification label or the rating of the next larger available size over current protection device,
where so recommended by the power source manufacturer.
If the main over current protection device is subject to road spray, the unit shall be housed in a Type 4–rated
enclosure.
Branch Circuit Overcurrent Protection
Over current protection devices shall be provided for each individual circuit and shall be sized at not less than 15
amps in accordance with 240.4, “Protection of Conductors,” of NFPA 70.
Any panel board shall have a main breaker where the panel has six or more individual branch circuits or the
power source is rated 8 kW or larger.
Each over current protection device shall be marked with a label to identify the function of the circuit it protects.
Dedicated circuits shall be provided for any large appliance or device (air conditioning units, large motors, etc.)
that requires 60 percent or more of the rated capacity of the circuit to which it is connected, and that circuit shall
serve no other purpose.
Panelboards
All fixed power sources shall be hardwired to a permanently mounted panel board unless one of the following
conditions exists:
1) All line voltage power connections are made through receptacles on the power source and the receptacles
are protected by integrated over current devices.
2) Only one circuit is hardwired to the power source, which is protected by an integrated over current device.
The panel shall be visible and located so that there is unimpeded access to the panel board controls. All panel
boards shall be designed for use in their intended location. The panel(s) shall be protected from mechanical
damage, tool mounting, and equipment storage.
Where the power source is 120/240 V and 120 V loads are connected, the apparatus manufacturer or line voltage
system installer shall consider load balancing to the extent that it is possible.
