- Using an RCD is better than a fuse because it requires no replacement sacrificial metal strip. Also, more reliable and reacts more quickly to cut the circuit (can detect quickly since it is a more sensitive device).

Can you use a 15 amp fuse instead of a 10 amp fuse for your car gauges?
It is NEVER a good idea to use a higher value fuse. The reason for the 10 Amp fuse is that it blows at 10 amps which the wire and device being protected is designed to handle. If you substitute 15 amps and that amount of current flows in your device, it may destroy the device and other things in the path of the current.
A device that contains a thin strip of metal that will melt if there is too much current through it?
A fuse has a metal strip that melts and opens a circuit if the current becomes too great.
What electrical safety device has a piece of metal that melts when a current becomes too strong?
A fuse.
What thing protect equipment from too much current by tripping a switch that breaks the circuit stopping the flow of electricity?
In electrical terminology it is an over current device. This could be an electrical breaker. Another form of an over current device is a fuse.
How fuse is a safety device?
fuse is a safety device because it dosnt harm us.
What is a protective device in the current path that melts?
A Fuse
What is the Simplest protective device for an electric current?
A fuse is the simplest protective device for over current in an electric circuit.
Which safety device will melt if the current is too big?
This safety device is called a fusible link that is situated inside of a fuse cartridge.
What is the term for fuse?
THis is the term. Fuse is a current sensing device that is set to open at a predetermined amount. Once current passing thru the device exceeds its rating it opens the circuit to protect the circuitry behind it.
An electrical device in the current path that melts or breaks when current exteeds a predetermined maximum value?
a fuse
How does a fuse help safety?
A fuse is a safety device that helps prevent excess current flowing in an electric circuit.
A device that protects a circuit from current overload is called what?
Fuse, Circuit breaker
What fuse is the fuel pump fuse?
A fuse is an electric device that interrupts the flow of electric current when overloaded. The fuse pump will therefore perform the similar task.
Difference between overcurrent relay and fuse?
Current is flow of electricity charge. Voltage is a measure of potential energy or charge. Fuse. Is a device that opens when the current rating is exceeded this stopping the flow of current.
How do you measure amperage across fuse?
Technically, you don't measure amperage ACROSS a fuse, you measure current THROUGH a fuse, and the units of measure are amperage. If you want to measure the current though a fuse on a single device, say a TV, or computer, you can use a multi-meter. You will need to 'redirect' all the current so it goes through the multi-meter. ie: ----|fuse|---|device|--- would be rewired to be: ----|fuse|-----|black probe|---|multi-meter|---|red probe|-----|device|------ If you want to measure the current through a larger fuse, like the main fuse in your house, you'll need a current clamp. This is a clamp that you can put on ONE of the incoming power wires. It measures the magnetic field generated by the current. This is the much easier way since you don't have to do any re-wiring to redirect the current, but costs more money. ----|fuse|---@@---|device|--- [the @@ is the current clamp, note that it doesn't matter where the current clamp is placed, so long as it's only around ONE wire] Whatever you do, be careful, electricity is dangerous.
What is the difference between rated current In and tripped current?
"Rated current" is the current the device (motor or transformer?) is designed to handle at full load. "Tripping current" is the current where a protective device (fuse, breaker) will open to protect the device from overload/overheating. "Tripped current", may be the current the tripping device measured prior to making the decision to trip, if you are reading this from a digital protective device like a relay or OCR.
Why are fuses in plugs?
to provide 'over current' protection due to overload or failure of the appliance, device and also the associated wiring. If the appliance or device draws more current than allowed, the fuse will melt first and open the circuit thus stopping the flow of current. Without a fuse there would be no limit to the current being drawn, the device and also the wires feeding it could overheat or even catch fire. The plug provides a convenient location for the fuse and also allows the fuse to be appropriately sized for the particular device being used.
