A standard fuse size for a current of 315 amps would not be practical due to the high current flow. It is recommended to use alternative protection devices such as a circuit breaker or contactor for currents of this magnitude.

What does fuse rating of 5 amps mean?

A fuse rating of 5 amps means that the fuse will break the circuit if the current passing through it exceeds 5 amps. It acts as a safety measure to protect the circuit from damage due to excessive current flow.


How many amps should a low voltage fuse be rated for?

The amp rating of a low voltage fuse should be based on the maximum current that the circuit is expected to carry under normal operating conditions. It is important to select a fuse with a rating slightly higher than the expected current to prevent nuisance blowing, while still providing adequate protection for the circuit in case of a fault.


What size fuse should you use to protect a circuit carrying 6 amps?

A breaker or fuse in an electric panel is protecting the wire, outlets and switches that are part of the installed circuit. You could plug in an appliance that draws 6 amps and have a 15 A breaker protecting the circuit. The idea for protecting a specific device is to put in a fuse that blows before the current destroys the device. If your 6 Amp device would be destroyed by 6.1 amps then you want a 6 amp fuse. However, fuses aren't that precise so this would be hard to do. A rule of thumb is that the steady state current in a circuit is 80% of the over-current protection. In your case this would be 7.5 amps.


Can you use 20 watts or 30 watts in a fuse?

No, watts are a measure of power while fuses are rated in amperes (amps). To determine the fuse rating, you need to calculate the current in amps by dividing the power in watts by the voltage. Then, choose a fuse that is rated equal to or slightly higher than the calculated current in amps.


What happen when a fuse wire of 100 ampere is used when a circuit at home draws a maximum current of 20 ampere?

The fuse or breaker should be no bigger than specified for the wiring and devices on the circuit. Your nominal current draw may be 20 amps, but a short circuit would cause maximum current to flow which in this case would be 100 amps until the fuse blew.

What does 5A mean in a standard fuse?

In a standard fuse rating system, the "5A" designation indicates a 5-ampere current rating. This means that the fuse is designed to safely carry a maximum current of 5 amperes before it will blow and interrupt the circuit. It is important to select a fuse with the appropriate ampere rating to protect the circuit from overcurrent conditions.

Will a 700 watt toaster trip a 10 amp fuse?

To determine if a 700-watt toaster will trip a 10-amp fuse, we first need to calculate the current it draws. Using the formula ( \text{Current (I)} = \frac{\text{Power (P)}}{\text{Voltage (V)}} ), and assuming a standard voltage of 120 volts, the current would be approximately 5.83 amps (700W ÷ 120V). Since this is below the 10-amp limit, the toaster should not trip the fuse under normal operating conditions. However, if there are other devices on the same circuit, the total current may exceed 10 amps and could cause the fuse to trip.

What is the difference between a 3 amp fuse and a 13 amp fuse?

The difference between fuses is the current that they are designed to support. A fuse is intended as a safety measure to protect against overload. A 3 amp fuse should burn out if more than 3 amps is run through it, with some allowance for standard variance. A 13 amp fuse would burn out with greater than 13 amps. It is always a bad idea to use a fuse bigger than you need, because if your component is designed for a 3 amp fuse and you use a 13 amp fuse, there is a good chance you could damage your component with too much amperage because the fuse would not burn out at 3 amps, as was intended.
