Standard sizes for fuses and fixed trip circuit breakers, per 240.6, are 15, 20, 25, 30, 35, 40, 45, 50, 60, 70, 80, 90, 100, 110, 125 , 150, 175, 200, 225, 250, 300, 350, 400, 450, 500, 600, 700, 800, 1000, 1200, 1600, 2000, 2500, 3000, 4000 5000, and 6000 amps.
What are the sizes of fuses?

What is the largest standard fuse size?
The largest size fuse shown in the chart is the 5AG , or “MIDGET,” a name adopted from its use by the electrical industry and the National Electrical Code range which normally recognizes fuses of 9/16” x 2” as the smallest standard fuse in use.
How do I know what size fuse to use?
The fuse rating can be calculated by dividing the power used by the appliance by the voltage going into the appliance. I (Amps) = P (Watts) ÷ V (Voltage) .
What are fuses sized by?
One common misconception about choosing the correct fuse size is that it's dependent on the load of the circuit. Actually, the load of the circuit should have nothing to do with choosing a fuse size. The fuse size should be based on the SMALLEST wire (largest gage number) in the circuit .
Are all fuses the same size?
Top Tip! 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.
How do you size a 12v fuse?
Find the size of fuse by multiplying the amps required by the device (2) by 1.5 . 2×1.25 = 2.5 then we will round up to the nearest fuse size (in multiples of 5 amps) which would call for a 5 amp fuse.
What are the 3 types of fuses?
- DC Fuses.
- AC Fuses.
- Cartridge Fuses.
- D – Type Cartridge Fuse.
- HRC (High Rupturing Capacity) Fuse or Link Type Cartridge Fuse.
- High Voltage Fuses.
- Automotive, Blade Type & Bolted Type Fuses.
- SMD Fuses (Surface Mount Fuse), Chip , Radial, and Lead Fuses.
What are the big fuses called?
Blade fuses (shown at right) come in six sizes, which are, from smallest to largest: Micro2 ® , Micro3 ® , Low Profile MINI ® , MINI ® , ATO ® /ATC ® (also called “regular”) and MAXI ® or MAX .
What is a standard fuse?
In electronics and electrical engineering, a fuse is an electrical safety device that operates to provide overcurrent protection of an electrical circuit . Its essential component is a metal wire or strip that melts when too much current flows through it, thereby stopping or interrupting the current.
What fuse do I run my remote wire to?
Amperage off the remote turn on isn't very high. Doesn't require much to switch amps/etc on. A 3-5 amp fuse should be more then enough.
How many watts can a 10 amp fuse handle?
10 Amps x 120 Volts = 1200 Watts .
Do fuses have a lifespan?
Typically fuse use shelf life / life expectancy is 10 years .
How do you size a fuse for a motor?
Some prefer to size time delay fuses at 125% of motor full load amperes . This sizing will provide a degree of overload protection for motors with a service factor of 1.15. Sizing fuses at 125% of motor nameplate amperes in some applications may result in nuisance fuse openings.
Does fuse size matter?
It also can cause problems with the amplifier as the AC power is continually going on and off. I recommend replacing the fuse with the proper size and then seeing what happens. The fuse doesn't power the unit nor does it protect the unit in most cases.
