Chapter 13 – Circuit Analysis using Laplace Transforms
... Circuit Analysis using the Laplace-transformed circuit Although Laplace transforms can be used effectively to solve differential equations, this is not the preferred approach when analyzing circuits. Instead it is easier to analyze the circuit directly in the s-domain. Advantages to working directly ...

... Protection of tap conductors in motor groups: The new 31.4.3 will require all motor tap conductors, i.e. conductors that carry current from a single motor, to have an ampacity, per Table 28.1, that is coordinated with the overall size (ampere rating) of the motor group. Manufacturers may need to mod ...

Circuit breaker
A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. Its basic function is to detect a fault condition and interrupt current flow. Unlike a fuse, which operates once and then must be replaced, a circuit breaker can be reset (either manually or automatically) to resume normal operation. Circuit breakers are made in varying sizes, from small devices that protect an individual household appliance up to large switchgear designed to protect high voltage circuits feeding an entire city.
