What ampere fuse is used for the kav-500 amp - Krell KAV2250 Amplifier

Fuses are made by type and rating in AMPS, just take it to a auto parts store and have them match it, it is likely just like fuses used in cars and trucks.

Start by checking under the driver's side kick panel, or under the hood on the driver's side.

Fuse boxes can be located in a number of different places, depending on the model.

To remove a fuse:

• With glass cartridge or blade-type fuses, a special fuse removing tool can be used to remove a bad fuse.
• Blade-type fuses are easy to remove by hand or with a needle nose pliers.

To replace a fuse:

• Be sure to replace a fuse with the correct one for the application.
• SFE (Society of Fuse Engineers) and all-glass cartridge (sometimes called "Bussman" or "Buss") fuses will interchange with one another, so care is required.
• Be sure that the fuse is the correct rating. Too low an amp rating will result in burned fuses. Too high a rating can cause a fire.
• Check the end of the fuse for its amp rating. The correct amp rating of the fuse to be used is listed on the fuse block.
• Fuses are generally numbered, and the main components abbreviated.

Typical fuse box or panel.

• On late-model cars, there may be icons or symbols indicating which circuits they serve. This identification system is covered in more detail in the owner's and service manuals.

NOTE
To calculate the correct fuse rating, use Watt's law: watts ÷ volts = amperes. For example, if you are installing a pair of 55-watt fog lights, divide 55 by the battery voltage (12 volts) to find out how much current the circuit has to carry. Since 55 ÷ 12 = 4.58, the current is approximately 5 amperes. To allow for current surges, the correct in-line fuse should be rated slightly higher than the normal current flow. In this case, an 8- or 10-ampere fuse would do the job. NOTE
It's advisable to carry an assortment of spare fuses in the glove compartment. It is difficult to know when one will blow. Also, you should learn borrow a fuse from a less critical circuit. For example, it is possible to do without power for the radio or air conditioner, if a fuse is needed for the headlights or brake lights. Make certain, however, that the fuse borrowed and later replaced has the same current rating. Remember that a blown fuse was caused by something going wrong. Replacing the fuse may or may not give a temporary solution to the problem.

May have to use a f'use tester to quickly test all of the fuses in the fuse box.

Sounds like the volume was way up when the iPod turned on. iPods are DC and cause a sudden thump through the speakers when they power on.
If the fuse is not blown, there may be another fuse you have not seen. Most amps have three to five fuses especially a 150watt/channel like the Krell.

I agree with the last answer- your amp has built in fuses that should be rated at 30 amperes each which should be sufficient as the amp only pulls 60 amperes at full power-however you may want to upgrade your power /ground wires to a good 4 gauge set if you dont already have it set up like that-throw an 80-100 amp fuse up front by the battery in case your running another amp for mids and highs just to cover the current draw of the amps combined. If the amp is still blowing fuses after that check to make sure that your subs are wired to no lower than a 2 ohm load as the amp is only stable to 2 ohms.

Hi,

Check the ampere rating of your compressor, which is indicated in the nameplate. you can size up your fuse from there. the ampere rating of your fude should be bigger than the compressor amp rating.

Hope it helps

You didn't mention which fuse it was that blew; I assume you mean a house fuse, not the Bunn's.
Since you mention a fuse rather than a circuit breaker, again, I assume this is the screw-in type that must be replaced each time it fails.
Check your Bunn for the rated power consumption; it should be shown somewhere on the machine and is likely somewhere between 1000 and 2000 watts.  You need to find how much current the machine is drawing.
Divide the given wattage by your line voltage which is probably (if in the US) ~120 Volts. For example: (from the Bunn) 1200 Watts/120 volts = 10 Amperes  
That means that when the Bunn is heating water, it will need 10 amps just for itself.  If, for example, you have a microwave oven using that same fuse that has a rating of 1000 watts power to cook with, it will actually draw ~ 1400-1500 watts from the wall plug.  Again, 1500 Watts/120 volts = 12.5 Amperes
Now we have a total of 22 1/2 amps of current if both are operating at the same time or if any other appliance such as a toaster (also draws a bunch) is being used, you will most likely blow a 20 amp fuse if not instantly, perhaps after a few minutes.
Fuses are designed to blow in a few milliseconds if hugely overloaded or to be patient for a minute or two if the over-current is mild; say 21 amperes.  
Over-fusing may be dangerous since the fuse rating is related to the gauge of wiring in the circuit it protects. This means that you need to move the Bunn to a different circuit so you don't accidentally exceed the fuse rating with two high-powered appliances if turned on together. 

Go by the fuse rating on the amplifier as a default. i.e. - If on amp has a 40 amp fuse on the outside and another has a 30 amp fuse on the outside, then you need to supply at least 70 amps of current. the formula works like this: amps X volts = watts. Doing the math here, for an amp to produce 1000w of power @ your vehicle's 12v power, you need 83 amps of current. Most cars produce 14v from the alternator when running, so this is really only needing 71 amps. Make sure your car's alternator can supply the excess current when running. Most modern amplifiers are efficient enough to produce their wattage with even less current than that.
