There are still small pockets where that is not the case. Adopted means legislated into effect and enforcable for each state/locale.
Where?
Direct quote.
"Adopted in all 50 states, NFPA 70, National Electrical Code (NEC) is the benchmark for safe electrical design, installation, and inspection to protect people and property from electrical hazards."
NEC 70
Guidance document meaning non-enforcable. It also means optional to comply with any or all of it. No one is questioning the years of best practices compiled into NEC 79.
Again it is not a "guidance document"
Direct quote from the title.
"Electrical Standard for Industrial Machinery"
All macinery sold in the US in not built to NFPA 79. is also a standard for purchased equipment and easilly approved by FM and other Insurance Co's. Yes equipment from the EU is sold in the US.
That statement above in red is part of an NFPA infomercial. It starts with "thou shall" and quickly back-pedals.
Until it is legislated into effect, it holds no more legal weight than a comic book. Customers of equipment purchased may spec to NFPA 79 but that is a business - business transaction requirement.
Machines can be built to both. German machinery is 90 percent of what I have maintained in my career and they have been under both standards. The only hiccup was wire labeling for a few years but NFPA has "Harmonized" the labeling requirements. I remember back around 2010 ish time frame when all the euro cable manufacturers changed their labeling to meet NFPA standards
What? NFPA 70 is the NEC.
And every motor sold strictly prohibits the use of wirenuts? Really? Probably most are silent on that detail.
Didn't say motor manufactures, I said machine builders, but at least one wasn't silent, see link in post 6!
You have selected fire pumps to make your point. Fire pumps are considered expendable when life safety and building destruction is present. The mindset is to run it until it dies or burns up with the rest of the building. A very different situation than the other 99.9% of motors installed with overload protection settings to shut down the motor and protect it.
YOU asked where in the NEC does it prohibit. Even though its listed in the attachment, that you obviously didn't read
YOU still asked. I have made most of my point on NFPA 79 but
YOU asked
No one is questioning the years of best practices compiled into NFPA 79.
Yet you and many others here are. I am baffled by those that would say that wire nuts are just fine even if you just want to call them "best practices"
Don't your customers deserve "best practices"? The operators of the machinery, do they deserve protection by observing "best practices"
I don't know about you but I always made sure my wife and kids would see me at the end of the day and the operators of the machines I maintained were able to do the same by observing professional standards, or "best practices" if you wanted to call them that.
And logically if one believes in "best practices" why would one say a method that is contrary to them is ok because "its just voluntary"
