Do I need an inline fuse for LED lights?
These LED lights draw less amps than your standard incandescent lights.
You should not need a circuit breaker of in line fuse.
However, you can install an inline fuse if you feel that you need one..
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.
Can I use a 5 amp fuse instead of a 3 amp?
No. The current rating of a fuse means the fuse will open when the rating is hit. … Fuses protect the equipment being used as well as the power side of the circuit. If you need to use something NOW and the fuse is a 3 Amp slow blow you could use a 5 Amp fast blow without much worry.

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 size fuse do I need for LED light bar?
A 10 amp fuse will protect the circuit. The 16 gauge wire will handle 10 amps in the length of wire that you will be using. The switch is rated for 20 amps. So, the 10 amp fuse will protect the circuit from overload.
What size fuse should I use for my amp?
Fuse ‘A’ must be rated to protect wire ‘B’. Any fuse rated at less than ~150 amps is sufficient to protect a 4g wire and the vehicle but I generally recommend a 125 amp fuse with 4g wire….Wire GaugeRecommended Maximum Fuse Size4 awg125 amps6 awg80 amps8 awg50 amps10 awg30 amps7 more rows
How many watts can a 5 amp fuse take?
Fuse ratings45 AMPFor circuits of more than 13kw (13000 w)13 AMPFor appliances between 700 and 3000w (3kw)5 AMPFor lighting circuits. The maximum permissible load of a lighting circuit is 1200w or 12* 100 watt lamps3 AMPFor appliances up to 700 watts, such as table lamps and alarm clocks3 more rows
How many amps do LED light bars use?
LEDs use about one-fifth the power for the same amount of light output. So for your light bar, it would consume one-fifth of the current, i.e. 0.2 amps from a 120 VAC source, or 2 amps from the car battery.
Do LED light bars need a relay?
A relay is an electrical switch that lets a low current circuit control a high current circuit such as a large LED light bar. … If you are using a light pod that does not have a very large amp draw, you may not need a relay switch, but if you are using a larger LED light bar, they are a must have.
How many volts can a 10 amp fuse handle?
240 VoltsVolts = Watts / Amps 2400 Watts / 20 Amps = 120 Volts. 2400 Watts / 10 Amps = 240 Volts.
What size fuse do I need for a cigarette lighter?
Ever wondered what the appropriate fuse amperage for a cigarette lighter is? Well, it’s recommended that you use an amp fuse with an amperage between 7 and 10, but never anything over 15.
