Ampacity

Figure 6 provides an additional example of taps to serve lower-ampacity loads from higher-ampacity circuit breakers-only from different series of circuit ❋ Unknown (2010)

Also, a conductor rated one-third the ampacity of a feeder conductor may be tapped from the feeder provided its length is not greater than 25 ft and it terminates in an appropriately sized OCPD. ❋ Unknown (2010)

In practice, the 600 A circuit breaker may contain a lower-ampacity trip unit to avoid the necessity to oversize the incoming cable. ❋ Unknown (2010)

The 4/0 cable must terminate on a circuit breaker of the correct ampacity, namely 225 A or smaller. ❋ Unknown (2010)

In brief, the rules for tapping feeder circuits indicate that a conductor rated 10% of the ampacity of a feeder conductor may be tapped from the feeder, provided it is not greater than 10 ft in length and it terminates in an appropriately sized OCPD. ❋ Unknown (2010)

Conductors equal to the full ampacity of the circuit breaker must be extended to the power terminal block ❋ Unknown (2010)

Figure 3 illustrates a 2,500 A breaker frame with a 1,600 A trip unit (higher ampacity trip units are available to the full-frame rating). ❋ Unknown (2010)

The feature is normally used for paralleling cables to feed the full ampacity of the breaker to a load. ❋ Unknown (2010)

The number and size of loads in an industrial control panel or NEC installation frequently require a circuit breaker 800 A or greater to be used as a main device, with lower-ampacity circuits tapped from it. ❋ Unknown (2010)

Yeah, [we should] [call it] ampacity! They'll NEVER [figure it out]! ❋ Elmo Toads (2010)
