Both legs of a 240 branch circuit need to be fused with a fuse rated at 240 volts or better. The voltage potential across the load is what governs the fuse voltage ratings.

A fuse is not used for?

A fuse is not used for increasing electrical current. Fuses are designed to protect electrical circuits by breaking the circuit when there is an overload or short circuit, preventing damage to the circuit and potential fire hazards.


Is a circuit breaker an alternative fuses?

Yes, a circuit breaker serves as an alternative to fuses. Both are designed to protect electrical circuits from overloads and short circuits by interrupting the flow of electricity. However, circuit breakers can be reset and used multiple times, whereas fuses need to be replaced after they have "blown."


A circuit breaker is used in many homes instead of a?

fuse. It is a safety device that automatically switches off the electrical circuit when it detects an overload, preventing overheating and potential fires. Circuit breakers can be easily reset after they trip, unlike fuses that need to be replaced.


Why you use cartridge fuse in control circuit of motor?

It is proper "control sense" to fuse the control circuit. It does not have to be just a cartridge fuse, in many cases it is a breaker. Depending on where the control voltage is obtained from, transformer from the incoming motor feed, separate source, or line voltage, there is always a chance that a component of the control circuit could fail, circuit protection would lessen the damage to other equipment in the control circuit. The fuse should be sized as close to the control current as possible.


What has replaced fuses in the main fuse box in a house?

Circuit breakers have replaced fuses in many modern homes. Circuit breakers offer better protection against overloads and short circuits, and they can be reset rather than needing to be replaced like fuses.

How fuses are rated?

Fuses are rated by amperage (current) and voltage. The larger the current need, the larger the rating of the fuse, to handle the current. The voltage rating of a fuse defines the maximum value of circuit voltage in which the fuse can be safely used. A fuse should not be used in a circuit with a voltage exceeding the voltage rating of the fuse.


What are the fuse amps for a 1992 Hyundai Scoupe?

Each circuit has a specific fuse rating. You can generally get the owners manual online from the manufacturers website at no charge, the fuses are listed there.


What device protects an electrical circuit?

An example of a circuit protection device is a fuse. Another example is a circuit breaker.


What is the working of fuse?

In each live line supply either household automotive or even commercial there is a fuse which when the current exceeds that fuses capacity it blows thus protecting the circuit


How are fuses and circuit the same?

Well, they are not. A fuse can be one part of a circuit. It limits the amount of power that can flow through the circuit.


Are diodes and fuses the same thing?

no. a fuse protects a circuit from overload, while a diode is a component of a circuit.

What do you do if the fuses keep blowing?

Find out why the fuse is blowing. You have a short or the circuit is overloaded.


What is a alternative to fuses?

An alternative to using a fuse is to use an electrical circuit breaker.


What can cause fuses to blow?

Overloading the circuit, short in the wiring, or incorrect fuse installed which is too small for the circuit. Always use the correct size fuse.
