Will this extention cord work?

I find it funny that large brand name appliances aren't even always ul listed themselves... I have serviced $500k machines that arent... I wonder does this make them illegal to use in a business?

We design industrial OEM equipment, and most of the time the components we use need to be UL or CUL (if used in Canada) approved. Not all commercial electrical components are, so this can be a challenge. Our panels and power transmission cables (since they are usually custom) and such themselves do not need to be UL certified, as there is no requirement for such, they just need to be able to pass inspection. OSHA rules, and specific manufacturing facilities regulations can augment NEC code to even stricter levels.

UL certification and listing isn't a mandatory requirement unless local/state laws require such, it is just a consumer peace of mind type of thing.

In my opinion, UL has proven to be more of a racket than anything. It is definitely a customer piece of mind thing and just says that a third party has inspected it and deems it safe for its intended purpose. Those inspections aren't cheap which is why many cheaper products won't be UL listed. Just because something is UL listed does not make it better than something that isn't.

In an industry I used to work in a lot of our customers wanted our products to be UL listed as an assembly, but since it was usually customized, that required everything to be re inspected by UL. Even if every component you use is UL listed, once you assemble those components into a new assembly it requires a new listing. Even changing a fuse to a different brand/type required a re-inspection.

Sorry for the rant...

It takes longer to understand the principles than read the rules.
