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.
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
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?
What is the standard ampere rating for fuse?
Because too high a voltage could arc across the fuse or could cause fuse to fail in other ways not related to normal operation.
What us the rating of the fuse which is most Commondly fitted to three pin plugs?
If you are referring to the standard plug used in the UK, then the maximum rating fuse is 13 A, which can supply a load of approximately 3 kW. But the fuse fitted must match the power-rating of the load, so lower-rated fuses are available; for example, a 3-A fuse can supply up to about 700 W.
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).
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.
How many volts in 30amps?
All fuses have a voltage rating, which is independent of its current rating. The current rating is the maximum current the fuse will pass; any higher, and it will blow. The voltage rating is the maximum voltage that is allowed to appear across the fuse should it blow. If the voltage is any higher than the fuse manufacturer's rating, it may arc across inside the fuse, causing power to continue to be supplied to the faulty item that caused the fuse to blow in the first place. This is obviously very dangerous, and could result in severe electric shock, or fires. The voltage rating is usually stamped on one end of the fuse.
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.
What can you do as preventative maintenance for a power pole transformer so that the mineral oil does not boil?
Lower the rating of the primary fuse feeding the transformer.
