The Vanguard 72-88 MFD [115V] Start Capacitor is an electrical replacement component intended for compatible pool, spa, or aquatic equipment control systems. Electrical parts must be selected by exact rating and application because amperage, voltage, capacitance, fuse type, terminal style, and mounting format can vary between systems. This item is useful when restoring proper equipment operation after a failed protective device, capacitor, or control component has been diagnosed. For safety, installation should follow the equipment manufacturer's service instructions and applicable electrical codes. Always shut off power before service and verify the original component markings against part number BC-75 before ordering. Replacement electrical component for compatible equipment applications Helps restore proper operation when the original electrical part has failed Match voltage, amperage, rating, terminal style, and mounting configuration carefully Professional installation is recommended for electrical service work Use part number BC-75 and the existing component label to verify compatibility
