This 10 Pack add a circuit standard fuse with heat shrink end lets you tap power from a standard blade fuse slot and still keep the original circuit protected. You just plug the add a circuit into the spare slot then fit the existing fuse plus a new one sized for your gear. It is handy when you want to run small loads like gauges or lights without cutting the factory loom.

Each add a circuit uses standard blade style terminals with an insulated lead of about 100 mm and a heat shrink end so you can finish the join and know it is solid. Grab a pack of 10 and you have enough bits for a full touring setup across ute, wagon and trailer. The layout keeps fuses easy to see in the original box so fault finding on the road stays simple.

Q: Can I use these add a circuit holders in both interior and engine bay fuse boxes?

Yes, they can be used in either location if the fuse box uses standard blade fuses. The plastic body and insulated wire suit typical automotive environments. For engine bays, make sure the added accessory wiring is routed away from high heat parts. Always check clearances so the new holder does not foul the fuse box cover.

Q: Do these holders come with fuses included in the pack?

No, this pack includes only the add a circuit fuse holders with heat shrink ends. You choose and install fuses to match each accessory and the original circuit. This lets you size the fuse rating correctly for lights, radios or other gear. Always match ratings to the cable size and manufacturer guidelines.

Q: What size fuse type fits these add a circuit connectors?

These holders are made for standard automotive blade fuses. Mini or micro blade fuses will not seat correctly in this style of head. Check your vehicle fuse box to confirm it uses the same standard blade footprint. If the blades line up with your existing fuses you are good to go.

Q: Can I run high-draw accessories like air compressors from these add a circuit leads?

These are better suited to low to moderate current accessories rather than heavy-draw gear. High current loads are usually safer on a dedicated fused line direct from the battery. Always check the cable size and circuit rating before connecting big loads. When in doubt talk to an auto electrician for advice.

Suitable for use in automotive fuse boxes that accept standard blade fuses. Allows an additional fused circuit to be added without cutting factory wiring. Ideal for powering low-current accessories from an existing fuse position where capacity allows. Always match fuse rating to accessory and vehicle manufacturer recommendations.
