Exporting machines: American codes for electrical parts 1

[freddy]

Introduction: We are a small firm in Italy and we build little machines for agriculture (kind of stirrers for manure). Those machines are obviously composed of mechanical and electrical parts: an electric motor and a low tension switchboard. I mean, nothing special, just a normal little machine.
Problem: we are selling one in Napa, California and I am concerned about the electrical parts: do I need to certificate something? Do I have to follow special codes? Do I have to ask my client what kind of electrical alimentation they have (I mean, is 60 Hz the rule everywhere in the States? which tension do they have beyond 110V?)? May customs block the machine if they don't see special certification they may look for?
I would appreciate if somebody can help us.
Regards, Alfredo

Many customers and clients are looking for a UL (Underwriters Laboratories) label and the compliance with National Fire Protection Association (NFPA), Inc. standards or codes, for example NFPA 70-1999 National Electrical Code (NEC) as a minimum.
