2.9.4
Metal-enclosed Bus Test
Each shop-assembled section of metal-enclosed bus shall be subjected to a
low-frequency dielectric withstand test of 2,200 volts for 1 minute between
each conductor and the other conductors, and between all conductors
connected together and the grounded metal housing in accordance with [IEEE
C37.20.1][IEEE C37.20.2][IEEE C37.20.3].
