Why circuit breaker are connected in series with load?

Updated: 4/28/2022

Because it needs to be able to cut the power to the load. That's why circuit breakers are always the first piece of equipment in a circuit after the power supply.

Does a refrigerator have parallel and series circuits?

A Refrigerator is technically a series because if one wire goes out all of the others go out

What is voltage divider circuit?

The two resistor voltage divider is used often to supply a voltage different from that of an available battery or power supply. In application the output voltage depends upon the resistance of the load it drives.

Is 150 a lot of power?

I'll assume you mean 150 Watts in which case it isn't that much power. It would depend on the circuit from which you are drawing this power to ultimately determine if it is "a lot of power". A typical house in the US has 120V circuits with 15-20A breakers which would allow the circuit to handle a load of 1,800-2,400 Watts.

How do i Make a 8 ohm speaker 16 ohm?

You can't change the ohm load of a speaker. What you can do, is get a second 8 ohm speaker to run with that speakers in series and you will get a total ohm load of 16 ohms.To run them in series, simply wire the positive terminal of one speaker to the negative of the other speaker. One speaker will have an open positive terminal which you wire to the positive terminal on the amp, and same goes for the negative on the other speaker (to the amp's negative terminal of course).

A fuse or circuit breaker used in a circuit is usually inserted in?

A fuse or circuit breaker used in a circuit is usually inserted in series with the load.

How does a house use a series circuit?

The most common form of a series circuit in a house is a circuit breaker (optionally in series with an on-off switch) in series with a load, usually a light bulb.

Can a thermostat cause a breaker to trip?

If it is a line thermostat and it is connected across the line instead of in series with the load then yes it will trip the breaker.

What is oil circuit breaker?

An oil circuit breaker is a breaker that is immersed in a tank of insulating oil. The tank has two electrical bushings through the tank to allow the supply and load to be connected to the breaker. These breakers can be opened under a heavy amperage load. The insulating oil is used to extinguish the arc that is produced when opening a switch under load.

Which circuit the ammeter connected in parallel?

An ammeter is always connected in series and a vlotmeter in parallel

How is ammeter and voltmeter attached to a circuit?

Ammeters are connected in series with the load under test. This requires the load be disconnected from the source, and the ammeter placed in circuit. Voltmeters are connected in parallel with the load under test. This does not require any circuit changes. Sorry, but WikiAnswers does not support illustrations.

What size circuit breaker should be used on 125 feet of 4 AWG power feed?

The circuit breaker is used to protect the conductor that is connected to it from an overload condition. On a motor load the breaker has to be sized 250% of the motors full load amperage. Some circuits can be only loaded to 80% capacity and this is governed by the sizing of the breaker. Without knowing what the load amperage is, this question can not be answered.

Can multiple circuits be connected on one breaker?

Multiple wires can be connected to one breaker but the one breaker IS a circuit. As long as the load is not more than 80% of the breaker capacity (example: a 20 amp breaker can only have 16 amps or 1920 watts at 120 volts) then by code as long as the load is not a specialty outlet of some sort, you can have as many outlets you want.

Can I add a circuit breaker wired in parrell to a current breaker to reduce the load on the breaker?

Adding a circuit breaker in parallel with an existing breaker may not reduce the load on the breaker. It is important to size the breaker according to the electrical requirements of the circuit and not to bypass the original breaker. Consult with a qualified electrician to ensure the proper installation and function of the circuit breaker.

Does mcb trip if a short circuit occurs?

Yes, a breaker will trip if there is a short circuit occurring on the breaker's connected load. The breaker will also trip on an overload condition when the current rises above the breakers trip set point.

Why does a transformer blow the circuit breaker on the primary side if it is not connected to a load on the secondary side?

A normal transformer should not blow the primary side breaker when it is not connected to a load on the secondary. If it does, something is wrong. Check for shorted or burned windings. Make sure that it is indeed disconnected from the load - it might still be connected to something that is also presenting a fault.

Can the power to your whirlpool be on the same 20 amp circuit as the bathroom lights and outlets?

No, the whirlpool has a motor load connected to it and should be connected to a dedicated ground fault breaker.
