Note 1: 50 Kvar, 100 Kvar, 200 Kvar, 250 Kvar, and 400 Kvar Three Phase Capacitor Banks will utilize three phase capacitor units. 
All other capacitor banks will utilize single phase capacitor units.
Refer to Table 6 for standard single phase capacitor units used in Type MELP capacitor banks.
Refer to Table 7 for standard three phase capacitor units used in Type MELP capacitor banks.
Note 2: Consult Gilbert Electrical Systems for this rating.
Note 3: Fixed bank only. Consult Gilbert Electrical Systems for a switched bank alternative.
