What is the amperage of the dash cam fuse?
4 Answers
The rated current of a dash cam is 0.8-1A. Generally, a 1.5-2A fuse is sufficient. The function of the fuse is to protect the circuit (wiring) and electrical equipment. When the circuit current exceeds twice the rated current of the fuse, it will blow within seconds to protect the circuit. The following are the installation steps for the dash cam fuse: 1. Open the fuse box cover; 2. Firmly pull the upper left and right corners of the fuse box; 3. The circled one is the cigarette lighter fuse, pull it out; 4. Insert the cigarette lighter fuse below and the dash cam fuse above; 5. Pry slightly at the circled area to open the side panel; 6. Pass the wire through the marked line; 7. The ground wire screw, a hexagon socket screw, can be installed successfully.
I remember when I last installed a dash cam in my car, I carefully researched the fuse amperage. Generally speaking, dash cams most commonly use fuses between 3 to 5 amps, depending on the device's power consumption and your car's electrical system. From my own experience, I chose a 4-amp fuse because the dash cam averages about 0.5A power draw, and going slightly higher helps prevent overload. If you're unsure, first check the device manual or measure the current - don't install randomly to avoid damaging the wiring. Other systems like audio typically use 5-10 amp fuses, but dash cams are simpler. I'd recommend watching some tutorial videos to locate your fuse box before starting, to avoid disassembling the wrong components. Remember - safety first. Too large a fuse risks overcurrent, while too small leads to frequent blowing. 3 amps is a safe starting point.
From my experience installing multiple dash cams, the fuse amperage should be determined case by case. Most dash cams have low power consumption, typically around 0.5-1A, so a 3A or 5A fuse is sufficient. I've used 3A fuses before—they effectively prevent short circuits without blowing too frequently. If your vehicle frequently goes on long trips, I'd recommend adding some redundancy with a 5A fuse, but don't overdo it to avoid compromising circuit protection. Also, when installing the dash cam, don't overlook other details like ensuring secure wiring connections to prevent loosening, and using a high-quality cigarette lighter adapter for safety. When replacing fuses, use pliers to gently pull and insert them, being careful to avoid electric shock. Overall, don't skip this step—using excessively high amperage fuses could lead to overheating hazards.
I've modified my dash cam a few times, and the fuse amperage is usually between 3 to 5 amps. It depends on the device's power consumption - 3A is sufficient for low-power recorders, while higher-powered ones require 5A to prevent overload. I typically use a multimeter to measure the current before deciding. Remember, the vehicle's main circuit can handle up to about 10A, so don't exceed that limit. Safety tip: Regularly inspect the fuse box to prevent wiring deterioration. Other systems, like light socket fuses, are around 10A. Always disconnect power before working to ensure safety.
