Unless otherwise specified in the Drawings and/or Bill of Quantities, the kvar rating (reactance) of the reactor shall be 6 % to the kvar rating (reactance) of the capacitor to where the reactor will be connected.
The reactors shall be securely fastened and installed in a separate compartment of the power factor correction board. If necessary, rubber pad shall be used to reduce noise.
