Aerpro AP404 8GAx2/8GAx2 Distribution Block

Aerpro AP404 8GA x2 to 8GA x2 Dual Isolated Bar Distribution Block

The AP404 is a distribution block from Aerpro with two isolated bars, each accepting two 8GA connections, providing a clean dual-bar power and ground distribution point for car audio installations. Constructed from solid brass with gold-plated contacts, clear Perspex covers, and hex set screw terminals.

Product overview

The Aerpro AP404 features two isolated brass bars, each accepting two 8GA cable connections via hex set screw terminals. The isolated bar configuration allows the AP404 to serve as both a power and ground distribution point in a single block, with each bar kept electrically separate. The solid brass construction with gold-plated contacts provides low-resistance current transfer at each connection point. Clear Perspex covers protect the terminals from accidental short circuits while allowing visual inspection without removing the cover.

Features and benefits

Two isolated bars for power and ground distribution: The dual isolated bar configuration allows the AP404 to serve as both a power distribution and ground distribution point in a single block, with each bar kept electrically separate from the other.

8GA x2 per bar: Each isolated bar accepts two 8GA cable connections, providing two input and two output connection points per bar for flexible distribution in car audio installations.

Solid brass construction with gold-plated contacts: Solid brass provides low-resistance current transfer at each connection point, with gold plating for corrosion resistance and reliable long-term contact performance.

Clear Perspex covers: Clear Perspex terminal covers protect against accidental short circuits while allowing visual inspection of the cable connections without removing the cover.

Hex set screw terminals: Hex set screw cable connections secure cables firmly without requiring specialist crimping tools, allowing straightforward installation with standard hex key hardware.

FAQ

What is the Aerpro AP404?

The AP404 is a distribution block from Aerpro with two isolated bars, each accepting two 8GA connections, providing a clean dual-bar power and ground distribution point for car audio installations.

What does the two isolated bars configuration mean?

The AP404 has two separate brass bars, each electrically isolated from the other. This allows one bar to be used for power distribution and the other for ground distribution in the same block, keeping positive and negative connections physically separated and electrically independent.

What cable sizes does the AP404 accept?

The AP404 accepts 8GA cable on all connections, with two connections per bar. Using cable sizes outside this rating may result in inadequate clamping force at the set screw terminals or insufficient current capacity for the connected circuit.

Do the Perspex covers need to be removed to inspect the connections?

No. The clear Perspex covers allow visual inspection of the terminal connections without removing the cover, while still protecting the terminals from accidental short circuits.

How does the AP404 differ from the AP406 and AP410?

The AP404 features two isolated bars each accepting two 8GA connections, suited to combined power and ground distribution in a single block. The AP406 accepts two 4GA inputs and distributes to four 8GA outputs on a single bar. The AP410 accepts a single 0GA input and distributes to four 4GA outputs. The correct choice depends on your cable gauge requirements and whether you need combined power and ground distribution in a single block.

Is the AP404 suitable for both power and ground distribution?

Yes. The two isolated bar configuration makes the AP404 suited to use as a combined power and ground distribution block, with one bar for positive connections and one bar for ground connections, kept electrically separate.
