Fuses are rated by amperage (current) and voltage. The larger the current need, the larger the rating of the fuse, to handle the current. The voltage rating of a fuse defines the maximum value of circuit voltage in which the fuse can be safely used. A fuse should not be used in a circuit with a voltage exceeding the voltage rating of the fuse.
Depends on the voltage across the fuse. For fuses rated below 9 amps, the two types are almost identical (MDL has slightly lower AC Interrupting amperages), and both are rated for use up to 250V. For fuses rated above 9 amps, the MDL fuses are rated for use up to 32V, while the MDA fuses are rated for use up to 250V. More info on Cooper Bussmann (link below).
Fuses are not rated in wattage, they are rated in amperage and voltage.
Fuses are rated in Amps. Although the physical size of a fuse is to do with volts; the further the terminals are apart the less likelihood there is of 'sparkover' between them.
The fuses for 2000 Toyota Sienna is located in the engine compartment. The fuses are labeled as slot 12 and 13 and are rated at 15 amps.
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.
Constant temperature change due to fluctuating current/amperage draws weaken the metal inside fuses over time rendering the fuse unable to handle the rated load
Alternator fuses, also known as the main fuse, are found inside the engine compartment fuse box. The fuses are rated at 70 amps and have a negative and positive wire wired directly to it.
The voltage rating of a fuse has to do with how long the fuse is / how much dielectric strength exists between the two terminals that don't melt. If you use a fuse that is rated for too low of a voltage, it will likely melt for a fault condition, but the voltage is too high for the gap distance, so an arc will develop across the (open) fuse. So...the fuse does no good. It will not protect equipment if used at a higher voltage than it is rated.
No, watts are a measure of power while fuses are rated in amperes (amps). To determine the fuse rating, you need to calculate the current in amps by dividing the power in watts by the voltage. Then, choose a fuse that is rated equal to or slightly higher than the calculated current in amps.
Check your owner's manual. Fuses are color-coded by their rated current, which differs from model to model of car, as does the location.
Mini fuses
Most `T' fuses are rated in either 125 volt or 250 volts A.C. If you look at the metal end cap on one of the ends, it'll specify which voltage it's rated. The 1.25, is 1.25 amps at the rated voltage.
