What is the fuse rating for a kettle?
A standard 3kW immersion heater will require a fuse rating of 13 A. This is because, it draws a current of 12 A.
What is the functions of a fuse?
The function of a fuse is to stop the current from flowing by opening the circuit when the circuit amperage exceeds the rating of the fuse.
True or False The voltage rating of a fuse can be greater than the circuit voltage?
True. The voltage rating of a fuse must be greater than the circuit voltage.
Why does the fuse box in my house make a clicking noise when the heater clicks on?
The clicking noise you are hearing could be the heater is overloading the breaker and it is on the verge of tripping This could be caused by the heater being to large for the circuit. Check the amperage rating on the heater and the rating on the breaker It also cold be the circuit breaker is going bad and needs to be replaced by a qualified electrician These are 2 possible answers you also could have a bad (loose) electrical connection some where in the circuit
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.
Why is it not okay to use a fuse with a higher amperage rating in an electrical circuit?
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. A fuse of a higher rating than what is called for will allow a higher current to flow through the circuit which could cause the insulation on the wire to melt, the wire to burn open or components in the circuit to become unusable. Never over fuse an electrical circuit with a larger amp rated fuse.
What is the difference between 125V 15A fuse and 230V 15A fuse?
The voltage rating of a fuse (in this case 125V or 230V) defines the maximum circuit voltage that the fuse is safe to be used on. A fuse with a voltage rating of 125V should not be used in a circuit with a voltage greater than 125V. If a 125V fuse were installed in a 230V circuit and an overload current occurred, the fuse could explode.
What is fuse what is it made up of?
A fuse in its simplest form - is simply a short piece of wire that is weaker than the circuit it is protecting. When the current flowing through the circuit exceeds the fuse rating, the fuse wire melts - breaking the circuit.
What causes the 10amp radio and heater fuse to blow in a 1990 Cadillac Deville?
short circuit in the circuit
Why does the my dodge mini van engine fuse blows out?
The current flow in the circuit has extended the rating of the fuse.
What is the maximum current that can flow through a fuse?
A current rating of a fuse is designed to open a circuit at a specific current flow. This rating is imprinted on the fuse and lets you know what the maximum amount of current the fuse is designed to open at. A fuse is in the circuit to protect the conductor that the current flows through. Never over fuse a conductor's current carrying capacity.
Can is use a 32v fuse instead of a 125v fuse?
No. If the voltage rating of a fuse is too low for the circuit in which it is fitted then, when the fuse operates (i.e. its link melts), the circuit voltage might maintain the resulting arc within the fuse, and it will fail to protect that circuit.
