Frequently Asked Questions (FAQs)

1. What are electrical terminal blocks used for?

A terminal block is a modular, insulated block that secures two or more wires together. Factories use terminal blocks to secure and/or terminate wires. In their most basic form, terminal blocks consist of several individual terminals which are arranged in a long strip.

2. What amp terminal block should I use?

When looking for a terminal block, be sure that the chosen block can, in fact, handle the current that you expect to use plus 50 percent more. For example, if an expected current of 2 A is to be drawn from a block, then a terminal block with a current rating of 3 A would be sufficient.

3. Are electrical connector blocks safe?

Overheating and damage to a terminal block can occur when operating at too high of a current, which can present critical safety concerns. In general, it is recommended to select a terminal block with a current rating of at least 150% of the system's expected max current.
