Hello, we imported Electron-Beam Welding machine from EU to US. We invited UL inspector for the Field Inspection and received a lot of comments. While we working on UL's coments, our city's electric engineer refuses to approve the electric permit that we have open for connecting equipment to the electrical grid. Does City has authority to demand UL certifiation?
Any tips on how to deal with UL? Some of their comments are ridiculus. UL asks for UL logo on plastic switch on a unit that is built by Siemens in Germany.
