[PDF Version]When a power capacitor bank is connected to a feeder or service entrance a circuit breaker or a fused disconnect switch must be provided. Existing motors when no overload change is required. Can be switched on or off with the motors, eliminating the need for separate switching devices or over current protection.
2 All feeder protection breakers are recommended to be a minimum of 135% of the full load amperes of the capacitor current. 3 80% rated circuit breakers should be derated for effective current rating shown above.
Fixed power capacitor banks should only be used when the facility's load is fairly constant. When a power capacitor bank is connected to a feeder or service entrance a circuit breaker or a fused disconnect switch must be provided. Existing motors when no overload change is required.
A capacitor is properly sized when its full load current rating is 90% of the no-load current of the motor. This 90% rating avoids over correction and the accompanying problems such as overvoltages. Go to Content ↑ 1. If no-load current is known
In general, a breaker should be sized to withstand 125% of the load (or 25% more capacity) and no less. Oversized breakers might cause wires to overheat without interrupting the current flow. Undersized breakers, on the other end, may trip continuously under normal operation.
