Frequently Asked Questions (FAQs)

1. What is a power distribution block?

A power distribution block (also known as a power terminal block or an electrical distribution block) distributes electricity from a single input (power) source across several devices in a circuit.

2. Can I use a power distribution block for ground?

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. ... When using either type of distribution block, it is recommended to use a main fuse holder within 18 inches of the battery.

3. Why terminal blocks are used?

Terminal blocks increase safety by grounding, isolating, and protecting the other components in the electrical circuit. Terminal blocks are available with finger-safe connections to prevent electrical shock. And, terminal blocks can also provide test points, which add even more safety to the circuit.
