SO is a 600 volt senior service portable power cord with a neoprene jacket, a hard-service cord built for demanding portable power applications.
SO designates a senior service portable power cord rated at 600 volts with a neoprene outer jacket. The S indicates senior service, a hard-service rating for demanding portable use, and the O indicates the oil-resistant neoprene jacket. SO is built to supply power to tools, equipment, and machinery in industrial environments, with the neoprene jacket providing resistance to oils, abrasion, and weather.
As a hard-service 600 volt cord, SO withstands the flexing, dragging, and mechanical stress of portable applications, while the oil-resistant jacket suits it to environments where oils are present. It is a heavier-duty counterpart to the junior service SJO.
In commercial and industrial settings, senior service cords like SO supply portable power for demanding equipment. Recognizing the designation and its suffix is part of identifying cord suited to the application.
Because it is a hard-service 600 volt cord, SO withstands the flexing, dragging, and mechanical stress of portable applications while the oil-resistant neoprene jacket suits it to environments where oils are present, a heavier-duty counterpart to the junior service SJO.
