    UL-Listed Terminal Blocks

    The standard of safety.

    UL listed terminal blocks, or UL recognized terminal blocks, indicate that they have undergone rigorous testing to meet their set of safety standards based on the UL’s research. UL stands for Underwriters Laboratories and as one of the most well-regarded independent testing laboratories, there are a huge number of electrical devices that can be UL listed. UL safety certification is recognized worldwide. UL listed terminal blocks consolidate your control panel wiring while helping you control complex circuits, all with the highest standards of safety.

    What does UL listed mean?

    Since terminal blocks are installed inside a control panel, technically it is not a UL listed component but UL recognized component. UL recognized components and terminal blocks are products that will eventually become a part of a larger system which itself will be UL listed. So while technically a UL listed terminal block is UL recognized, the control panel it is installed in at Bay Power’s UL508a certified shop will be UL listed. Further, different UL listed terminal blocks are covered by different UL safety requirements depending on voltage ratings as well as their intended application.
