What minimum fuse rating is needed for a 12 volt circuit when using one 48 watt bulb?
The formula you are looking for is Watts = Amps x Volts. Amps = Watts/Volts. This comes to 4 amps load. Minimum size fuse would be 5 amps.
How do you calculate fuse rating?
First of all you need to observe maximum current at various possible supply condition (i. e. 220VAC to 260VAC). Then check the inrush current for the equipment. When you start an high power device then it draws 4 times more current than usual. Your fuse should also take care of inrush current. For example: if maximum possible current is 500mA then your inrush current may go upto 2A. Thus if you put a fuse of 600mA then everytime you turn on the device, it may burn the fuse. So the suitable fuse for such condition is 2A
How do you shut alarm off with no set of keys?
Disconnect the battery or pull the fuse to the horn then have an auto tech correct the problem.
How do you work out the difference in degrees centigrade and degrees Fahrenheit?
Use this formula to convert degrees Celsius (C) to degrees Fahrenheit (F): (C x 1.8) + 32 = FUse this formula to convert degrees Fahrenheit (F) to degrees Celsius (C): (F - 32) / 1.8 = C
What does 5V fuse look like?
No such thing as a 5V fuse. There is a 5 Amp fuse. These are availableat an auto parts store.
What is the correct formula for fuse rating?
Watts divided by volts = amps
What is meant by ratting of fuse?
A fuse is given a various rating (strength). For instance, a home appliance (washing machine, etc) would usually have a fuse with a 13 amp rating. While a low powered lamp would only merit a 2 or 5 amp fuse rating. It is important to use a fuse of the correct rating in amps for each electrical appliance.
A transformer is rated at 12V-0-12V and 250mA so what does the 250mA mean and how do you calculate the fuse for the primary winding without knowing the VA rating?
A: The VA rating is there 6v/a the power fuse to blow is 6watts. 050a fuse
How do you calculate the fuse rating level if the full load is 4 amp?
A fuse rating is normally the 120% of the rated full load current. So, 4 amps times 120% is (4x120%) = 4.8amps
What is the correct fuse rating to provide short-circit protection for a 100HP 200V 3-0 wound-rotor motor?

What happens if you use a fuse that's overrated for voltage but has the correct current rating?
Using a fuse correctly rated for current but "overrated" for voltage does not present a problem. Current ratings are critical safety issues, and fuses should be replaced with those of the same current rating. But using a fuse with an identical current rating but a higher voltage rating is not a problem. The reason for that lies in what the voltage rating of a fuse is. Fuses are given a voltage rating to state a maximum voltage in a circuit that they are designed to protect. And the voltage rating has nothing to do with the "normal" operation of the fuse. The fuse carries current when it operates normally, but when something happens and excessive current flows, the fusible link heats up and opens. This is where the voltage rating comes into play. It is possible that a fuse can arc through when it fails. It is the voltage rating that stands in the way of this. As long as the voltage rating of a circuit is not beyond the voltage rating of the fuse, that fuse will fail safely when it fails. It is acceptable to use a fuse of an equal current rating but a higher voltage rating when replacing a fuse that has failed.
It is ok to use a fuse with a higher amperage rating and not ok to use a fuse with a smaller amperage rating why?
It is ok to use a fuse with a higher amperage rating and not ok to use a fuse with a smaller amperage rating why?
How do you know the correct wattage of fuses?
Fuses are rated in amps not watts. You just replace the fuse with one of the exact same amp rating as the one that blew. The fuse is protecting the wiring which you normally cannot change. For that reason you must use the correct rated fuse.
What is the fuse rating of 600watt appliance on a 220 volt supply?
The fuse rating should be 5 amps
What is the current rating of T2L 250v fuse?
The current rating is 2A (2 amps).
How is the minimum fusing current related to the current rating of a fuse?
Each fuse has its own rating. It will be marked on the fuse somewhere.
