UL is a trusted source across the globe for product compliance. It shows that an independent laboratory has tested samples of products to safety requirements and conducts periodic checks of manufacturers’ facilities. UL has tested products for public safety for more than a century. WaterTectonics is proud to share that we can build and certify industrial control panels to UL 508a standards.  Below, our Engineering Manager Wayne is applying a UL 508a sticker to our first WT produced industrial control panel!
