Distribution Block Specifications

Distribution Block Type
This specifies what the intended use of the distribution block is. Fused distribution blocks are intended to be used with the power wire and the fuse acts as a short-circuit or surge protection so your amplifier is not as likely to be damaged. Non-fused distribution blocks can used with ground or power wire connections, but the protection on power wire connections will not be present as there is no fuse in the distribution block. Therefore, we recommend your amplifier has an external fuse for short-circuit or surge protection. When using either type of distribution block, it is recommended to use a main fuse holder within 18 inches of the battery.
Total Number of Inputs
This is the total number of input connections that go into the unit.
Maximum Input Gauge Size
This is the largest gauge wire that will fit into the power and ground terminals of this device. The lower the gauge number, the thicker the wire is. For example, a 4 gauge wire is thicker than an 8 gauge wire and thus has higher current carrying capacity. Always do your best to get this size wire to reduce the risk of damage to your components.
1/0 AWG
Total Number of Outputs
This is the total number of output connections that the unit will produce.
Maximum Output Gauge Size
This number refers to the maximum size of wire that will fit into the output connector(s) of the capacitor, battery terminal, or any other connector with an wire output.
Number of Fuses
This is the number of fuses that the item requires to work properly.
Fuse Type
For accessories, this is the type of fuse that is required for the item to work properly.

For fuses, this is the type of fuse.

Mini ANL

Why did you choose this?
Sonic Electronix Store
I chose this product so that I can transition from 1/0 gauge wire to 4 gauge wire, which is a size that my amplifier will be able to accept. I also wanted a solution that would offer the option of future expandability while also adding in output isolation for individual amplifier protection. The SHD821 seemed to be the best option for the price.

Need a fused distribution block with allen screws instead of phillips head!
Marte C on Sep 8, 2014
