NFPA 70 - National Electrical Code (NEC) (USA) NFPA 70 is a comprehensive electrical safety standard in the United States, which includes the installation of electrical equipment, such as power distribution cabinets. This section concentrates upon commonly used power distribution equipment: Panelboards, Switchboards, Low-Voltage Motor Control. orldwide since the inception of this system in 1973. ABB's history in switchgear can be traced back even further, to the 1890's whe need for greater use able or lett able floor space. For example, high value computer installations often require all data processing operations of national and. Managing and installing a rack power distribution unit (PDU) has never been easier than with the EL2P PDU. Designed to simplify deployment and take stress out of power distribution, this intelligent PDU helps reclaim valuable hours. for example; they're all about being an “electrical integration solution provider,” which means they know how crucial it is to offer high-quality and dependable products in this field.
