What is the definition of a final circuit?
Final circuit. A circuit connected directly to current-using equipment, or to a socket-outlet or socket outlets or other outlet points for the connection of such equipment.
What are sub circuits?
Subcircuits are self-contained circuits that appear as “black boxes” in other circuits. A given subcircuit may be used any number of times at multiple levels just as long as it does not become a subcircuit of itself. There are three types of subcircuits: cards, chips and plug-ins.
What is power subcircuit?
Power sub circuit It includes water heater, AC, refrigerators etc. The maximum load for power sub circuit should not exceed 3000 W. If the power load exceed above 3000 W, separate power circuit is taken.
What are the groups of final circuit?
There are three main types of circuits encountered in a domestic situation. They are ring circuits, radial circuits and lighting circuits.
What is the difference between a final circuit and a distribution circuit?
The cable supplying a final circuit must be capable of carrying the full-load current indefinitely without deterioration. However, a distribution cable may be sized to carry the maximum demand expected in normal operation on the basis that not all of the total connected load will be switched on simultaneously.
What is difference between circuit and sub circuit?
As nouns the difference between circuit and subcircuit is that circuit is the act of moving or revolving around, or as in a circle or orbit; a revolution; as, the periodical circuit of the earth around the sun while subcircuit is a distinct part of an electrical or other circuit.
What is sub circuit wiring?
A sub-main electrical circuit can be defined as a circuit connected directly from the main LV switchboard to a sub-main distribution panel or a rising main for final connection of the minor current-using equipment.
What defines a distribution circuit?
Distribution circuit means a three-phase set of conductors emanating from a substation circuit breaker serving customers in a defined local distribution area. This includes three-phase, two-phase and single-phase branches.
What is a radial circuit?
A radial circuit is a type of fixed wiring that feeds one piece of suitable cable from one power point to another. It continues in this fashion until it reaches the last point on the circuit and does not return back to the consumer unit or power source.
