NEC Violations? Eaton's ATS

90.7 Examination of Equipment for Safety.
For specific items of equipment and materials referred to in this Code, examinations for safety made under standard conditions provide a basis for approval where the record is made generally available through promulgation by organizations properly equipped and qualified for experimental testing, inspections of the run of goods at factories, and service-value determination through field inspections. This avoids the necessity for repetition of examinations by different examiners, frequently with inadequate facilities for such work, and the confusion that would result from conflicting reports on the suitability of devices and materials examined for a given purpose.

It is the intent of this Code that factory-installed internal wiring or the construction of equipment need not be inspected at the time of installation of the equipment, except to detect alterations or damage, if the equipment has been listed by a qualified electrical testing laboratory that is recognized as having the facilities described in the preceding paragraph and that requires suitability for installation in accordance with this Code. Suitability shall be determined by application of requirements that are compatible with this Code.
 
My guess is that he's objecting to the red conductors on what appears to be an EGC bus.

Why don't you at least tell us what you think is wrong? I don't see anything from the small pictures.

Hi,

The items that stand out to me are as follows:

Red wire used as grounding and ground

Ground bard mounted on paint

Wire harnesses are either not supported or poorly supported. The wire terminals are the support

Shoddy work on the wiring and door. The cut-out, protruding screws, and cable management leaves me with doubt that the ATS is reliable. Reliability is the main purpose for the ATS.

As pointed out in Post #2 and #3, the NEC is not the supporting document for your claims. Being EATON, there is little doubt it's LISTED so any perspective problems would need to be addressed by the manufacturer and the listing agency (UL, CSA, etc)
NEC is not applicable.
 
As stated this is not an NEC issue. I agree the craftsmanship leaves a lot to be desired. If you have upcoming projects you might let them know you will be using a different manufacturer
 
As Roger said, not an NEC issue, around here the poco uses white as a phase conductor, but they are not covered by the NEC. Many years ago Eaton was making transfer switches at their Arden NC plant, but that looks like Hecho en Mexico!

Thank you.

The next project will be ABB, but this panel needs to be cleanup before commissioning and I prefer that Eaton pays for it. The point of this post was for me to gather facts that will be used to justify needed changes.

I agree that the ATS is garbage but if it's listed equipment then there is likely nothing that can be done to force the manufacturer to fix it.

If you are not familiar with them check into Russelectric. I have not dealt with them since they were bought by Siemens but they were the Cadillac of switches IMO
 
Eaton had an issue with the motorized breaker transfer switches, the rollers were plastic or nylon, after a few transfers, they would flatten out or break. They went through and changed them to steel under a recall. Quite a few switches. Quite expensive because it involved a nighttime shutdown. The mechanical interlock cables were were bad to corrode and lock up, causing the switch to not return to utility. The fix for that, was to add a heater inside the switch enclosure.

Eaton never removes paint when installing ground bars. Some cans don't have paint in them but when they do and come with a factory bar there's still paint behind them

If the ground bar has been listed and tested with the paint intact then it is not required to be removed. No different than having a factory or field installed ground bar in a panel.
 
If something goes wrong, it will probably be the red wire.... I've seen worse in listed panels, but it is annoying when all the wires are the same color. Aircraft electronics is similar except all the wires are white.

I don't believe you need to scrape paint from a ground bar if the mounting screw threads have at least 2 threads engaged onto bare metal. It has 2 screws. Every panel they sell works that way.
