  • If fuses keep blowing: Diagnose wiring faults or overloads rather than increasing the fuse value.

Standard blade fuses (ATO/ATC, often called ATS). It does not accept mini or micro blade fuses.
What is the maximum fuse rating for this holder?
Up to 30A, provided the connected cable and accessory are sized appropriately.
Is 54394BL suitable for 12V and 24V systems?
Yes. The holder is rated 32V DC, so it suits both 12V and 24V automotive and marine circuits.
Does the holder include a protective cap for the fuse?
Yes. It features a cap to help shield the fuse from dust and splashes.
How do I install the holder in-line with my wiring loom?
Cut the positive feed, splice the pre-wired tails in-line using quality crimps or solder, then heat shrink for strain relief and moisture resistance.
Where should I mount it for best protection of the circuit?
As close to the battery or power source as practical so the entire downstream cable run is protected from shorts.
What fuse value should I choose for my accessory?
Select a fuse that protects the smallest cable in the circuit and matches the accessory’s current draw. Do not exceed the cable’s continuous ampacity.
Can I mount the holder in the engine bay or exposed areas?
Yes, if kept away from direct heat sources and moving parts. Secure the holder and loom to prevent vibration damage.
What should I check if fuses keep blowing in this holder?
Inspect for shorts to ground, damaged insulation, undersized cable, corroded connections or an overcurrent accessory. Do not upsize the fuse to mask a fault.
