What is a branch in electrical circuit?
Branch of Electric Circuit When an element exists between two nodes, the path from one node to another through this element is called branch of the circuit. The branch of an electric circuit can be defined more precisely, as the portion of the circuit between two nodes which can deliver or absorb energy.
Is Electronics and Instrumentation engineering a circuit branch?
Hi Nathu, Instrumentation and Control Engineering is not a secondary branch it is a vast interdisciplinary branch of engineering. Under this branch students learn to design, develop, install, manage and maintain instruments that monitor and control engineering systems, machinery and processes.
What are the three types of branch circuits?
Branch circuits are divided into four categories: appliance, general purpose, individual and multiwire (see Figure 1). With the exception of branch circuits that supply only motor loads, requirements for branch circuits are in Article 210.
How many devices on a branch circuit?
The maximum number of 42 overcurrent protective devices in one lighting and appliance branch circuit panelboard is specified in NEC 408.35. Article 408 also defined “power panelboard” as a panelboard having 10 percent or fewer of its overcurrent devices protecting lighting and appliance branch circuits.
What does circuit, branch mean?
A branch circuit is defined as that part of an electric circuit extending beyond the last circuit breaker or fuse. The branch circuits start at the breaker box and extend to the electrical devices connected to the service. Branch circuits are the last part of the circuit supplying electrical devices.
What is the definition of a small appliance branch circuit?
SMALL APPLIANCE BRANCH CIRCUIT. A circuit that supplies electrical energy to one or more outlets to which appliances are to be connected is called an appliance branch circuit. These circuits are not to have any permanently connected lighting fixtures that are not a part of an appliance.
