(203mm) deep was subjected to a load equal to the width of the shelf ininches times 3.0 lb (1.4 kg). Each shelf more than 8 in. but not morethan 16 in. (406 mm) deep was subjected to a load equal to the width ofthe shelf in inches times 5.0 lb (2.3 kg). Each shelf more than 16 in.deep was subjected to a load equal to the width of the shelf in inchestimes 7.0 lb (3.2 kg). Each load was uniformly applied along the entirewidth of the shelf, centered on a line at the mid depth of the shelf or4-1/4 in. (108 mm) in from the most extended edge of the shelf,whichever was farthest from the back edge. The load was graduallyincreased from zero to the specified value and maintained for 5 min.RESULTSShelf System Cat. No. Depth, in.

No. PPS/29/PL-1and Cat. No. PPS/12-6-8/J41 were electrically and mechanically connectedas intended. An alternating current of 25 A derived from a source withan open circuit voltage not exceeding 6 V was passed between thegrounding pin of Cat. No. PPS/25/PL-1 and any point on the adjacentraceway. The closed circuit voltage (CCV) was then measured betweenthese two points and the impedance calculated. The procedure wasrepeated a minimum of three times, each time the point or points ofsupply connections were changes. The grounding path was allowed to coolbetween each test.RESULTSCalculatedLocation CCV Impedance ohm1. The leg of PPS/29/PL-1 near .23 0.009cord entry2. By the conduit connector on .23 0.009Cat.
