Can I use a different amp fuse?

Do not replace a blown fuse with one that has a higher amperage rating. The fuse has a specific amperage rating because it is intended to be the weak link in the circuit to protect the electrical components. A blown fuse indicates excessive current has entered the circuit.

Can I use 10A fuse instead of 8A?

What is easily available is a 10A glass fuse. Will it be alright to replace the 8A 250V rated fuse with a 10A one….Replacing 8A Fuse with 10A Fuse.

Does it matter what fuse you use?

If you have only one amp, the fuse at the battery can be used to protect the wire and the amplifier. The fuse would need to be whatever was recommended by the manufacturer for the amplifier and would also need to be rated at or less than the suggested maximum current for the wire that you’re using.

Can I use a 32V fuse vs 250V?

Will this 250v 4 amp fuse work to replace a 4amp 32v fuse (in an old amplifier/receiver)? Answer: 250V is the max current the fuse can take, it is fine as long as that rating is at or above the current being passed through the fuse, in this case 32V. Howver for amps, you should use slow blow.

Can I use a 32V fuse in a 12v system?

It means a auto fuse is rated to operate with voltages up to 32 Volts, which includes 12 volt service. Therefore you shouldn’t use auto type fuses in like say 120vac applications.

Are fuses universal?

Not all car fuses are the same, and most cars have multiple fuses of varying sizes for different electrical components. When you are replacing a car fuse, it is essential to replace the blown fuse with a new one of the same type and size. You should also never replace a blown fuse with one of a higher amperage rating.

Are fuses interchangeable?

A fuse is composed of a housing, fuse element and contacts, and they vary in size and configuration. They come in either blade or cartridge-style. ATO fuses and ATC fuses are regular-sized automotive blade fuses. They are interchangeable, provided the amperage rating is the same.

What happens if I put a 5A fuse in a 10a plug?

Possibly yes. It is possible to short out a circuit by overdrawing more than 5 Amp by removing the 5 Amp fuse and putting in a 10 Amp fuse.

Why do I need to set the BOD for my AVR?

By default, this option is disabled. If your AVR uses a bootloader or the EEPROM, you must set the BOD for safety! SPI programming (SPIEN fuse), if this fuse is not enabled, the part must be programmed using high-voltage, and the SPI interface will not be usable (so no USBASP for you).

Why is my AVR not working?

Most common causes for dead AVRs, are wrong clock source settings (CKSEL fusebits), disabled SPI programming (SPIEN fuse) or disabled reset pin (RSTDISBL fuse). This circuit uses the parallel and serial high-voltage programming method: HVPP = high voltage parallel programming and HVSP = high voltage serial programming.

Why is my AVR running at 1MHz instead of 8MHz?

Clock Divide (available for some AVRs only), causes the chip to divide the clock rate by 8. So if the clock source is set to Internal 8MHz and you have this fuse set, then you’ll really be running at 1MHz. By default, this is turned on. Reset Disable, turns the Reset pin into a normal pin instead of a special pin (as it is set by default).

What is the brownout voltage for an AVR?

If the voltage decreases below 4.5V, the AVR may behave erratically, erasing or overwriting the RAM and EEPROM, it may also start running random piece of the flash program, all in one an action with unpredictable results, nothing you would want your hardware to do. To keep it under control, set the brownout voltage to 4.3V.
