JIC IEC IEE and bears oh my
(OP)
Greetings all!
I have recently discovered this area of the web and hope to become a contributing member.
I am recently employed a a company which creates One-Off mechatronics devices.
Beause of the nature of our machines it is cost prohibitive to submit each creation to the UL/CSA/TUV/XYZ agencies for approval/certification.
I intend to spec in UL approved sub-assemblies and give the customer a choice of schematic format.
My questions to you are;
1-Which of the several "Standards" are most prominent?
2-Whiich software would be flexible in such away to allow creation in the 2 most common "Standards"
3-Would you change this policy, if so please advise.
I thank you all

Disclaimer - await second opinions.
RE: JIC IEC IEE and bears oh my
You use an approved supply then low voltage covers the rest - same as panel shops. They don't get every single panel individually UL'd they instead run with a "UL shop" methodology. They use UL approved/labeled wire connectors, fuses, crimpers, etc,etc. They pay the graft, er,.. I mean fees required to be a UL panel shop and then the UL guy shows up occasionally to inspect things in general for a few $ and business continues. That's the mode I'd think you'd want to be in.
UL offers classes in running this way.

thank you much for your input.
The panel is basically the enclosure of r low voltage servo amplifiers and logical controllers.
Should we apply to UL for PAnel Shop status?
RE: JIC IEC IEE and bears oh my
CE + CE != CE
(the != means not equal)
In words, taking CE marked parts does to make a CE marked product. This is particularly true for EMC, but also applies to safety.
Let's take a simple case for say EN60950 (or IEC60950 or UL60950 if you prefer). You are not allowed to make a mechanicaly unstable product. It has to stand on an inclined ramp at about 10 degrees. If you put the parts in the wrong place it will tip over and therefore fail the standard. Using approved sub-assmeblies helps a lot, but it still requires extra work.

again I am in awe of the help provided here.
If I were to use UL508a, along with IEC 671 symbols on my drawings would I be covering most bets? How does the NFPA 79 fit into all of this?

To: jraef,
what would your suggestion be in this case as described above?
Most of our applications are in the US, but occaisionally the end user will ship to another country.
Which synbology should be used for US, and then which ones for acceptablitiy for most other nations?
What type of drawings should accompany the schematics?
Since we are getting requests for some kind of agency, UL et al, which would be the best choice?
RE: JIC IEC IEE and bears oh my
UL listed enclosure will definitely help you with all industrial installations and get the area electrical inspector to sign off on your projects.
Canadian project do require cUL but it seems even though you get it CSA approved before it ships the local CSA inspector will always inspect it anyway, (must be a scam) and of course in his opinion finds something wrong.
anything that ships to europe needs CE sticker, but this is a different animal altogether. Its not just components having CE stickers. I found the estop is totally different in CE countries versus the US. Other things I am sure are different. Electromagnetic interference, voltage interference, etc ... I am not that familiar with it but when I see a machine panel shipped from europe you will see Estop, finger safe, and of course CE marked devices. I believe their is more but I am not sure.
RE: JIC IEC IEE and bears oh my
It depends where you are going to be selling your products. UL is not necessary in Europe. CE marking is not required in the USA.
RE: JIC IEC IEE and bears oh my
Here in the US and you have any sort of computing power in the panels (or any high frequency stuff about about 32KHz) then you also have the joy of FCC approvals.....
And the list goes on.
