I'm interested in this idea of 'violations'
Home Depot/Lowes/Ace Hardware/and many other hardware/electrical stores sell
replacement cords for appliances, where you, the homeowner can replace a cord
with a new one. Does that void the UL guarantee and NEC (if there is one)
guarantee?
If it does, that means that those hardware stores are knowingly selling a
product, that if used will void guarantee's. Is that correct?
NEC and UL are independent organizations; not government bodies. Their
standards are voluntary, and do not carry the force of law.
NEC does nothing by write standards. The first chapter of the NEC
(National Electric Code) title "90.2 Scope" says their jurisdiction does
not apply to any kind of vehicles except motor homes and RVs.
(Infamously, they nevertheless added Article 625 which has specs for EVs
anyway, even though EVs are outside their scope).
The NEC also does not generally apply to cord-connected non-permanent
devices that people can simply move around and plug in or unplug
themselves (like a battery charger). Such devices are more typically
governed by UL requirements.
UL (Underwriters Laboratories) is an independent *testing* agency. All
they do is write test standards, and test products to see if they meet
them. Companies pay UL to test their products, as an independent
verification that the product is safe, and is built to normally accepted
industry practices (i.e. it's no worse than anyone else's).
If a complete product (like a battery charger) passes their tests, UL
can "list" it. Such a product will carry a "UL listed" label. If it's
just a component part (like a plug or a switch), UL can "recognize" it.
The part will then carry a "UR" label (UL Recognized).
Neither UL nor NEC have any power to pass or enforce their standards, or
regulate, insure, warrant, or guarantee anything. Compliance with their
standards is entirely *voluntary*. The only way that compliance becomes
mandatory is if some federal, state, or local law happens to say "must
be built according to NEC" or "must be UL listed" etc.
