Type 2 SPD installed as a Type 1 SPD in ATS for standby generator

[MrTomas]

Yes the conductor strands are poorly trimmed.
Check the instructions on the SPD, type 2 mat require connection to a 2 pole 20 or 30 amp breaker, not as shown
It’s violation to have more than one wire under a lug. The SPD nipple into the panel isn’t waterproof
All of which your inspector should find

Tom, can you point me to the NEC section for "It’s violation to have more than one wire under a lug."? Thanks!

 

[NEC Inspector]

110.3(B) - Equipment has to be installed in accordance with the instructions it was listed with. Those lugs are not listed by the manufacturer and the testing laboratory to have a tiny wire and a big wire under the same lug.

110.14 - Conductors of dissimilar metals shall not be intermixed in a terminal unless it is listed for that application. The surge protector I handled yesterday had tinned copper wires, and I am assuming that the one you have does as well. The big wire in that terminal is aluminum. Copper causes aluminum to corrode due to galvanic action.

Carbon monoxide detectors required per Generac installation instructions and per NFPA 72.

From what I can tell the generator is installed outdoors. Where would you put a carbon monoxide detector?

 

[Greentagger]

Required in the interior of dwelling.

 

[NEC Inspector]

Code section of NFPA 72?

It would not be required per Exception 1 of R315.2.2 of the International Residential Code unless the generator was installed indoors.

Because Mulder says trust no one.

It was this guy

The Cigarette Smoking Man (abbreviated CSM or C-Man; sometimes referred to as Cancer Man or the Smoking Man) is a fictional character and one of the primary antagonists of the American science fiction drama television series The X-Files. He serves as the arch-nemesis of FBI Special Agent Fox Mulder. In the show's sixth season, his name is said to be C.G.B. Spender, but Dana Scully suggests this is one of "hundreds of aliases"; the show's characters and fans continue to refer to him by variations of "the Smoking Man" because he is almost always seen chain-smoking Morley cigarettes, and because he was credited in the pilot episode and other episodes (such as the season 1 finale) as "Smoking Man". In the eleventh season, he reveals his full name to be Carl Gerhard Busch.

You may be correct. Thanks for the insight. I’m unable to access references for further comment or review. I have seen and read the requirement in Generacs manufacture’s installation instructions. With that no other requirements or references needed.

----------- UPDATE ------------
I asked my electrician to replace the Eaton Type 2 SPD with a proper Generac Type 1 SPD and he installed it like this...

I am ready to schedule the township inspection (my electrical contractor and electrician won't do it), and I want to be able to point out to the inspector any problems if he does not catch them himself. I assume there will be a question about the non-watertight connection on the right side. I pointed that out to my electrician and he said there is a gasket there, no problemo.
Anything else?

2 wires under the same lug. Bare neutral and spd neutral.
Also install instructions probably say to make the leads on the suppressor as short and straight as possible.
They ain't. JMO.

for 2 wires under the same lug, what is the NEC page for that? And, yes, the instructions recommend short and straight leads, but that won't fail an inspection, will it?

It would be under that manufacturer’s listing. Two wires under one lug is acceptable if the manufacturer lists that combonatiin. Don’t know of any manufacturer that would list that combination. As far as the leads go, that is the manufacturers recommendation, not requirement, so length will not get them turned down.

I am going to assume the ATS listing refers to the installation instructions, and those have nothing specified for wires under lugs, so now we are down to the labels inside the box...

See 110.14(A) and yes, the labels inside the ATS which refers you to the breaker info.

Let the inspector do his job then question him on what you think are problems. With that said I think this thread has run it's course.
