Given the continued growth of demand for the export of machines onto the North American market (USA, Canada), in 2003 Marchiani Flavio s.n.c. decided to increase the quality of its services, acquiring the ability to certify the panels according to UL508A standards.

UL 508 A refers to American standards:
NEC (National Electrical Code)
NFPA (National Fire Protection Association)
OSHA (Occupational Safety and Health Administration)
NEMA (National Electrical Manufacturers Association)
ANSI (American National Standards Institute)
NEC Article 409.1 clearly states that certified panels compliant with UL508A are considered to be standards for the NEC itself.
NEC Article 409.1 Scope. This article covers industrial control panels intended for general use and operating at 600 volts or less.
FPN:UL 508 A is a safety standard for industrial control panels.
NEC Article 90.7 confirms the above and reinforces the value of a UL certified panel.
Basically a UL certified panel can be exempt from controls of local authorities.
