626 Electrified Truck Parking Space
By Mike Holt
A new Article was added to cover the electrical
installation requirements for conductors and equipment that connect
trucks and transport refrigerated units to electric power within an
electrified parking space. This issue was driven by the U.S.
Environmental Protection Agency (EPA), which has been pressing the
transportation industry to reduce the idling of trucks at truck stops
as to reduce air pollution and the use of millions of gallons of fuel
each year. The intent of this article is to provide an electrical
standard for the transportation industry.
The new Article covers the electrical conductors and equipment
external to the truck or transport refrigerated unit that connect
and transport refrigerated units to a supply of electricity, and the
installation of equipment and devices related to electrical
installations within an electrified truck parking space.
A truck parking space is a location with an electrical system that
allows truckers to "plug in" their vehicles while stopped, and use
off-board power sources in order to operate onboard systems such as
air-conditioning, heating, and appliances, without any engine idling.
An electrified truck parking space may also include dedicated
areas for heavy-duty trucks at travel plazas, warehouses, shipper and
consignee yards, depot facilities, border crossings, etc. It does not
include areas such as the shoulders of on- and off-highway ramps and
access roads, camping and recreational vehicle sites, residential and
commercial parking areas used for automotive parking, or other areas
where AC power is provided solely for the purpose of connecting
automotive and other light electrical loads, such as engine block
heaters and at private residences.

Cables for use in Class 1, Class 2, and Class 3
remote-control, signaling, and power-limited circuits shall have all
which of the following markings on the cables? Disregard any

- The proper type letter or letters for the type of wire or cable as
specified elsewhere in the Code.
- The manufacturer’s name, trademark, or other distinctive marking
by which the organization responsible for the product can be readily
- The AWG size or circular mil area.
- Cable assemblies, where the neutral conductor is smaller than the
ungrounded conductors, shall be so marked.

Avoid Safety Violations
A dangerous shock hazard exists when electronics operate with the panel
door open. Avoid the danger and OSHA fines. EXAIR’s low cost Cabinet
Coolers stop electronic control downtime with cold 20 degree Fahrenheit
air and maintain the NEMA 4, 4X and 12 rating of the enclosure.
Thermostat control minimizes air usage. Web site offers detailed
