enclosure at a level higher than the lowest live part.
SA13A.1 added January 27, 1995
SA13A.2 The water spray test apparatus is to consist of three spray heads constructed in accordance
with the details shown in Figure SA13A.1 and mounted in a water-supply pipe rack as shown in Figure
SA13A.2. The water pressure is to be maintained at 5 lb per square inch (34 Kpa) at each spray head.
The distance between the center nozzle and the converter or inverter is to be approximately 5 feet (1.5
m). The marine converter or inverter is to be brought into the focal area of the three spray heads in such
a position and under such conditions as are most likely to result in entrance of water into the marine
