How do you calculate mcb rating?
Circuit breakers are used to protect the conductor that is connected to it. The sizing of the conductor is based on the current of the load. As the connected load current is increased so must the wire size to accommodate that higher current. Therefore as the wire size increases so must the breaker size to accommodate the higher load current.
How are circuit breakers connected with the other elements in a circuit?
Both of these devices are safety devices used to open a faulted circuit and stop the current flow.
What is a circuit with no load?
An open circuit or a short-circuit (if that circuit is complete).
What is open circuit voltage when load is connected?
As load is conected in circuit , so thre is no open circuit therefore there would not be any open circuit voltage.
What is caused by a short circuit?
A short circuit is a low resistance connection where one is unexpected. It causes a diversion of current from the intended load, and, since it is usually a higher than expected current, it often causes the protective device (fuse, circuit breaker, or relay control logic) to trip.
What are the kind of circuit?
the electrical circuit, load, conductor, open circuit, switch,
What does the conductor in a circuit do?
A conductor carries the voltage potential from the source to the load, i.e. the wires from a circuit breaker to a light.
What is the meaning of short circuit conductor?
A short circuit conductor is just a conductor in an unexpected location, often with much lower resistance that is expected for the normal load.
How do you do a simple circuit?
You require a power source, a conductor and a load.
What size fuse required to supply a continuous load of 32 amps?
80% of 40 = 32 amps Load the circuit breaker to 80% choose a conductor to suit the circuit Breaker min.
How could you use your open circuit to test is a material is a conductor or insulator?
Connect your material to the gap of the open circuit and see if the load(e.g bulb) works, if it does then the material is a conductor and if it doesn't then it's an insulator
Why must a fuse always be connected in a non-earthed conductor?
It is the ungrounded conductor that carries the load current. It is that conductor that needs to be protected should a fault current occur. That is what the fuse in that circuit does.
What circuit exists when a conductor of conductive material of low resistance connects across the conductors in a circuit somewhere between the source and the load?
a "short" one
What are the effects of having too many circuits plugged in?
Circuits are not plugged in. An electrical circuit is the way the voltage from the electrical panel boardis supplied to the load that is to be energized. Circuits come in many different capacities depending on the circuit breaker and wire size that connects to the circuit's load. If the load is greater than the capacity of the circuit's conductor that the breaker protects, then the breaker will trip and drop the overload current offline. This protects the conductor and the ciruit's load from fault damage.
What is the conductor called that feeds current from a residential meter to the residential load center or circuit breaker panel?
Meter 'tails'.
What are the essential elements in a circuit?
a power supply a conductor and a load the extra element is a switch not nessary but a part of it most of the time
Why switch is always connected in the phase wire?
First of all, the correct term is 'line' and not'phase' wire. The reason a switch is always placed in the line conductor, rather than in the neutral conductor, is that its function is not simply to break the circuit, but also to ensure that the circuit's load is disconnected from the line potential. If the switch were to be placed in the neutral conductor, it would still break the circuit, but the load will still be at line potential and present a shock hazard to anyone attempting to work on the load (e.g. to remove a lamp from its holder).
