UL Certification

UL Certified Control Panels

M-Tech is proud to be an Underwriters Laboratory (UL) approved facility. This means that we can self-certify, and label your electrical panels.

Most states and municipalities in the U.S. no longer require building inspectors to review, and approve industrial control panels. Instead most inspectors look to see if an electrical panel has an agency approval. Since UL is the most common approval, having the UL mark on an industrial control panel means that the inspector need only ensure the control panel has been installed for compliance with NEC or local codes. Without the UL mark (or another agency approval) most municipalities will not pass your final inspection until you have the panel inspected and a certification label affixed to the panel.

Using UL listed or recognized components does not constitute a UL approved panel. You must have your panel built by a UL facility to get the certification. M-Tech can help you meet the UL standards.

UL508A certifying and labeling an electrical panel is standard practice for M-Tech unless otherwise requested by a customer. No special requests or costs are associated with UL labeling at M-Tech. If a design does not meet the necessary UL criteria, we will notify you and develop a plan to correct the issue.

M-Tech manages agency inspections, fees, education, paperwork and other requirements so you don’t have to. A UL inspector visits M-Tech unannounced monthly to ensure we are following UL requirements. We work closely with our inspector, and UL to manage code changes and the use of components manufactured worldwide to ensure the safety of every panel manufactured by M-tech.
