Frequently Asked Questions
What is the difference between ATO and mini blade fuses?
ATO fuses (standard blade) are larger and typically rated from 1A to 40A, while mini blade fuses (ATM/APM) are about half the size and cover 1A to 30A. The choice depends on your fuse panel’s compatibility and the space available. Mini fuses are common in modern vehicles to save space, but ATO fuses are still widely used for aftermarket accessories.
How many circuits do I need in a fuse panel?
Count the number of accessories you plan to add, plus a few spare for future expansion. For a single additional device like a dash cam, a 4-circuit panel may suffice. For multiple accessories (lights, radio, compressor, etc.), 6 to 12 circuits are common. It’s better to have extra circuits than to run out.
Can I install a fuse panel under the hood?
Yes, but you need a panel with weather resistance (IP rating) and corrosion-resistant materials like tinned copper or stainless steel. Panels without covers or sealed housings are not suitable for engine bay use. Look for marine-grade or waterproof models if mounting outside the cabin.
Do I need a separate fuse for each circuit?
Yes, each circuit in a fuse panel has its own fuse to protect the individual device and wiring. This prevents a single fault from disabling multiple accessories. The fuse rating should match the wire gauge and load of each circuit, typically 5A to 30A for automotive accessories.
What wire gauge should I use with a fuse panel?
The input wire from the battery should be sized to handle the total current of all circuits (e.g., 10 AWG for up to 60A, 8 AWG for up to 80A). Output wires to each device depend on the load: 16-18 AWG for small loads like lights, 14-12 AWG for higher current items like amplifiers. Always use wire that meets or exceeds the fuse rating.
