    Top 2008 Code Changes
    626 Electrified Truck Parking Space Equipment
    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 so 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 trucks 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 parking 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.
