When should a capacitor bank be grounded?
Open the fuse cutouts. DO NOT ground the capacitor bank immediately after the bank has been disconnected from the system. For capacitor banks with capacitor units containing discharge resistors designed to discharge the capacitor unit from peak rated voltage to less than 50 V in five minutes, allow five minutes before grounding.
How do you ground a capacitor bank?
Ground the neutral of ungrounded capacitor banks. For a fixed pole-mounted capacitor bank, ground the jumper leads on the source side of the capacitor unit between the fuses cutout and capacitor unit terminal.
