UL Approval

[KingTamina]

[FONT=Arial, Helvetica Neue, Helvetica, sans-serif]Do I need an UL approval (or any test lab) if I build a machine(s) and use it in my own company internally? These machine are used by trained operators. They are low voltage machines using only 110 and 220 VAC. [/FONT]
[FONT=Arial, Helvetica Neue, Helvetica, sans-serif]Where can I find a legit documentation on this subject. [/FONT]:?[FONT=Arial, Helvetica Neue, Helvetica, sans-serif]

Thanks and Best Regards,[/FONT]

Since you are here in California, it's in the California Electric Code. In a nutshell, any electrical assembly of 5* or more components (including the box) must have a separate NRTL listing. The list of acceptable NRTLs is the list maintained by OSHA. If you Google "OSHA NRTL list" you will find it.

Now that said, if you don't pull a permit and it's not going to be inspected by an AHJ, only you would know. But you might want to check with your insurance carrier or officer at your company that does that, because a lot of industrial insurance policies will have a rider or statement to the effect that any equipment installed must have appropriate third party approvals and/or installed per code even if not inspected. Where that bites you later is if there is a fire or accident and they investigate, finding unlisted assemblies gives them a way of not paying out. Remember, UL stands for Underwriters Laboratoies, as in INSURANCE underwriters. Protecting the insurance companies from loss was and still is their primary mission.

* Might be 3 now.

Do you know taking a look at Underwriters Laboratories's archive test results is not easy. I have tried.:?

Not sure what you mean by that. It's relatively easy to look for whether or not a component is UL listed, they have a website for that. A custom assembly built by a UL-508A panel shop, which is what I was referring to, is a totally different matter.
