UL698A panel shop

First, McIver Engineering & Controls is certified to manufacture UL 698 control panels to the NRBX designation for UL 698, which is for industrial control panels that will feed into or control hazardous locations. This UL698A designation further states that these control panels cannot be located in hazardous locations. For example, a UL 698A-certified industrial control panel, certified to the NRBX designation, requires “intrinsically safe” components, such as control circuits. Per UL Standards, these “intrinsically safe” components shall mitigate ignition risks as the environments will likely be near, but not in, environments where flammable gases, vapors, liquids, combustible dust, or any other particle-igniting elements may be present. In simple terms, to be “intrinsically safe” means to be usable around gases or fuels without risking static electricity or heat exchange causing ignition with the surrounding volatile particles.

While NRBX designated UL 698 control panels are located away from the hazardous locations, UL698A category NNNY control panels are located in an environment that has the presence of flammable gas, liquid, vapor, or dust. Due to the increased risk of peril, the NNNY designation for industrial control panels certified to UL 698A is much more stringent. Because explosions are a higher risk in environments containing these flammable particles, any industrial electric control panel certified to 698A with the NNNY category designation must be built in a panel capable of containing any possible explosions of circuitry, sparks, or arcs within the electric control panel, which must also be NEMA Type 7 and non-incendive.
