The Painless Performance 20-Circuit Pre-Wired Universal Fuse Block is the command center for any custom wiring project, hot rod, kit car, or classic car rewiring. It provides a complete and organized power distribution hub with 20 fused circuits, pre-terminated input leads, and labeled outputs that make aftermarket wiring projects faster, cleaner, and more reliable.

This fuse block features 20 color-coded circuits with individual blade-style ATO fuses rated from 5 to 30 amps per circuit. The block includes two battery terminal power input studs rated at 100 amps continuous, six ground distribution studs, an integral alternator charge wire terminal, and a horn relay pre-installed. The housing is heavy-duty glass-filled nylon rated to 250 degrees Fahrenheit continuous. All terminals are tin-plated copper for corrosion resistance. Included mounting ears accept standard #8 screws or rivets.

Using a Painless fuse block converts a spaghetti nightmare into a clean, traceable wiring system. Troubleshooting becomes as simple as looking for the circuit label and checking the fuse. Each circuit is pre-wired with color-coded 14-gauge output leads — no need to strip, label, or organize loose wires. Installation requires mounting the block, connecting the battery and alternator inputs, and routing output leads to your accessories.

If you're building a custom car, stop piecing together wiring. Get the Painless 20-Circuit Fuse Block and build a reliable electrical foundation.

Frequently Asked Questions

How many circuits does the Atech fuse block support for my auxiliary electrical system?

The Atech fuse block supports between 6 and 12 fused circuits depending on the specific model. Each circuit is independently fused with ATO or mini-blade fuses for individual protection. The Atech fuse block includes a negative bus bar and cover for a clean organized installation. This Atech block provides a central distribution point for auxiliary accessories like lights, fans, pumps, and audio equipment.

Can the Atech fuse block handle the total amperage of my added electrical accessories?

The Atech fuse block is rated for a maximum total amperage typically between 60 and 100 amps depending on the model. Each individual circuit should not exceed the fuse rating specified by the Atech block design. The main power input to the Atech fuse block must be protected by a circuit breaker or fusible link rated for the total amperage. Proper wire gauge must be used for each circuit based on the amperage draw of the connected accessory.

Does the Atech fuse block include the fuses or do I need to buy them separately?

The Atech fuse block may include a selection of fuses or come without fuses depending on the specific product. Some Atech blocks ship with an assortment of common fuse ratings for initial setup. Other Atech models require you to purchase the specific fuse ratings needed for your accessories. Check the Atech product description to see if fuses are included or need to be purchased separately.

Can I mount the Atech fuse block in the engine bay or should it be inside the cabin?

The Atech fuse block can be mounted in the engine bay if it is equipped with a weatherproof cover and sealed construction. For maximum corrosion resistance mount the Atech block inside the cabin or in a protected location like the glove box or under the dashboard. The Atech block compact size allows flexible mounting options in tight spaces. If you mount the Atech block in the engine bay ensure it is protected from direct water spray.

What gauge wire should I use to power the Atech fuse block from my battery?

The main power wire feeding the Atech fuse block should be sized to handle the total potential current draw of all connected circuits. A 4-gauge or 6-gauge wire is typically sufficient for a Atech block with a 60 to 100 amp total capacity. Use a circuit breaker or fusible link within 12 inches of the battery to protect the main feed wire. The Atech block input terminal accepts wire sizes up to 4-gauge on most models.
