UL certification
UL is a nationally recognized safety certification organization. For electric signs, the UL mark helps identify the sign as a certified electrical product.
National Electrical Code
UL certification supports the product side of electrical safety, while the installation still needs to meet local electrical code and inspection requirements.
Local sign rules
Cities can also regulate sign size, placement, brightness, zoning, permits, fasteners, and who is allowed to install or connect the sign.
