Underwriters Labratories listings for presses?

Hello, we are building a new shop in Madison, WI and just moved the presses in. The electrical inspector says in order to be able to connect them the presses must have a UL listing. Either this is off base or these machines do have listings as they are all very common to the industry. Does anybody have any insight or information on listings for:
Heidelberg platen GT
Heidelberg K Series cylinder
Miehle V50
Kluge 12x18

Any help is greatly appreciated!

The NEC (National Electrical Code) is very specific about what needs to be listed and what does not. For example, the requirements that luminaires (light fixtures) be listed is in section 410.6 (google “NEC 410.6” to check). In addition to the NEC there are OSHA and local regulations.

Before you go down the road of looking for a listing, ask why the listing is required. I would ask the inspector what code section / regulation he/she is citing to that requires the presses to be listed. The codes often leave a lot up to interpretation and having a conversation about the source regulation can be helpful.

I am curious to know whether these presses were listed when they were manufactured.

https://standardscatalog.ul.com/standards/en/standard_775 might be relevant?

“These requirements cover products that are intended for use in printing establishments. Included are such products as sheet–fed, web–fed, and offset presses and controls, composing and typesetting machines, cutting and folding machines, and other products that are used in the preparation of mats. The products covered are for connection to interior wiring systems in accordance with the National Electrical Code , and are rated at 600 V or less.”

Looks like you have to purchase it to see the detail however.

The Free Presse,
We are on this side of the pond.
Speaking of water once my motors were submerged in water and at that time there were no underwater laboratories. But after everything dried out
it all went back to work.
Lang, the specs should be on the motor plates an electrician should be able to go from there. UL listings
seem to be a thing of the past nothing that comes from China has them. From what I understand; a UL listing protects the consumer for instance if you by a lamp or fan
or radio, an appliance you should be able to let your 5 year child old hang from the cord and the so called appliance survives the assault and you can’t sue them.
I suspect your local inspector is green around the edges.

I would talk to a few commercial/industrial electricians or electrical contractors, and choose one who you want to hook up the machines for you. I’m sure there are many of these firms in Madison. Tell them the problem and I’m sure they can get this solved. They are much more likely to be able to satisfy the electrical inspector, and with a minimum of hassle.

Double post, sorry. I didn’t think it worked the first time..

Thanks all, I appreciate your time.
It seems ridiculous but I’m hoping we can get through it soon! I’m working out of a friends bindery till we can get occupancy.

Saw a situation that was similar once and the owner just had outlets installed on the walls near equipment and had flex cords installed on the machines The outlets where rated for current and voltage also had a disconnect switch at the site and passed inspection.

i have never seen a “UL” sticker on a press. the motor yes, i guess. the components themselves, okay. not a complete machine. Madison is full of nutcases… i am just east of you in Waukesha.

I never had to worry about this, I had qualified electricians do my installs, it was up to them to pull any permits. That being said, they didn’t always do that. I guess if I was in your situation, I’d let the electrician take responsibility.

I am quite certain that the electrical inspector was referring to the electrical connections/ disconnect and associated enclosures.
Since it is a new connection on old equipment, it is considered a NEW DEVICE INSTALLATION and all electrical connections, boxes, conduits need to be upgraded to the latest NEC requirements.
