New IEEE Standard – Superseded. This standard applies to all overhead, pad-mounted, dry-vault, and submersible single-pole or multipole ac automatic line sectionalizers for rated maximum voltages above 1000 V. It covers service conditions, ratings, design tests, production tests, and construction requirements.<\/p>\n
