How do I know what size fuse for my amp?
The correct size of fuse to use depends on the amp you are wiring. If your amp has an internal fuse, then your inline car amp fuse should be a bit larger. For instance, if your amp has an internal 20 amp fuse, then you should go for a 25 or 30 amp inline fuse.
How many amps should my fuse be?

| Wire Gauge | Recommended Maximum Fuse Size |
|---|---|
| 4 awg | 125 amps |
| 6 awg | 80 amps |
| 8 awg | 50 amps |
| 10 awg | 30 amps |
What is a Class T fuse?
A Class T fuse is a fast acting, current limiting, fuse that is rated to interrupt a minimum of 200,000 amps. The Type T Fuse is offered in 300 volt AC and 600 volt AC versions. Type T Fuse ampere ratings range from1 to 800 amps. The Bussmann brand name used for Class T fuses is T-Tron,®.
Can I upgrade to 300 amp service?
Not many utility companies will do 300A services, some like Phoenix will allow a 320A service, but MOST will do a MINIMUM 400A 3-phase service. You should either call your utility company and ask for the high peak demand OR have a load study done on your existing service to determine if upsizing is really needed.
What size wire is needed for a 300 amp service?
For 300 amp, the right wire size is 500 kcmil. 400 amp service requires a wire size of 1,000 kcmil. For 600 amp service, we recommend a wire size of 1,750 kcmil.
How do I choose the right fuse?
How to Choose the Right Fuse
- Identify the type of voltage that is being protected.
- Observe the amperage of the electrical circuit that the fuse will be protecting.
- Size the fuse to its particular holder.
- Inspect the fuse for internal element replacement.
- Use a fuse that has an inspection window.
What size fuse should I use for a 1200 watt amp?
You should use at least a 100A fuse.
How do I know what size fuse to use?
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 do the letters on fuses stand for?
The number and the A (may be mA) is the amp rating of the fuse. The L denotes that it is a low breaking capacity or glass fuse (H is High breaking capacity and is usually a ceramic package). Taking the example above a T2AL250V fuse is a 2 Amp, Time Delay glass fuse rated for 250 Volts.
What is the difference between T and TL fuses?
Fuse manufacturers developed plug fuses with time-delay characteristics to compete with new circuit breakers. Type-TL and SL fuses are considered to be regular duty fuses. Type T and Type-S are heavy duty fuses for high inrush current applications and typically use a dual-element design.
