Do you need a 240 volt fuse in each leg of a 240 volt circuit or should you use two 120 volt fuses?

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.

What has replaced fuses in the main fuse box in a house?
Resettable circuit breakers.
Is a circuit breaker an alternative fuses?
Circuit breakers do the same thing as fuses. They interrupt current flow when a certain preset point is reached. The difference between circuit breakers and fuses are that circuit breakers are resettable and reusable, whereas fuses are one time devices that must be replaced after they blow.
Why fuse wire is placed in series with the device?
circuit breaker and fuses used in series to break the circuit in overcurrent situation to block current to flow through circuit.
Why are fuses used in the electrical circuits at home?
The fuse is supposed to be the weakest link in the circuit. The circuit is rated to handle a specific load current. The wire and insulation rating of the circuit is governed by this specific load. If this load malfunctions and the load current becomes higher that what is specified, the fuse is there to break the circuit. Never over fuse an electrical circuit with a larger amp rated fuse. <<>> for overcurrent protection nec art, 240
How do you find fuse capacity in house lightning?
To find the circuit's capacity you have to look at the breaker or fuse that protects that circuit. On the handle of the breaker you will see a number. that number is the tripping capacity of that particular breaker. On a glass screw in fuse you will see a coloured disk with a number on it that is the capacity that the fuse can handle before opening the circuit. On cartridge fuses the voltage and amperage rating will be printed on the body of the fuse.
What fuses should you use in your 67 Dodge Dart GT?
every circuit has a different rated amp fuse, it should say on the fuse box what amp to use for each circuit.
What does a fuse do?
Fuses protect circuit componentsNothing
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 is the work of fuse box?
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
What is a alternative to fuses?
An alternative to using a fuse is to use an electrical circuit breaker.
What has replaced fuses in the main fuse box in a house?
Resettable circuit breakers.
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.
