Can anyone spot what's wrong with this picture?

PS: It's not the missing generator feed!

Is that black box on the cabinet door supposed to be connected to the stuff inside the cabinet via that white cable that's hanging loose in there?

That looks like some sort of multi-conductor cable for controls or something...

Also it doesn't look like it would all fit nicely together once the door is closed.... [Linked Image]

It looks like you have a transfer switch that uses wireless normal electricity. [Linked Image]

I hope there is no CO for this building if that is a Article 700 transfer switch.

Also I do see any control wiring for the generator.

Sven you got it, the black box is the brains of the transfer switch, most times it will have an exercise clock to run the generator on a fixed schedule

It will also have a lot of settings for different functions.

The voltage at which transfer happens.

Time delays for re transfer and cool down cycles.

As long as the harness is unplugged it will not transfer or start the engine. When the door is closed you would see a LCD display and menu buttons.

The harness is unplugged and the feed from the generator is not pulled because when this picture was taken the switch was not complete. I don't have one of the finished product. There is something in the make up here that isn't right and there is an interesting story that happened because of it. I'll post tomorrow with details. [Linked Image]

Do the two ground wires go to a Burndy lug? ; or does the ground wire loop from one pipe to the other?

Since it's been awhile since I wired a transfer switch I'm gonna make a stab at it and say the normal power is landed on the generator lugs?

Nick, I’ve heard of red/green color blindness, but not blue/white color blindness.

While we are on the topic of transfer switches, I have a question. What is an overlapping neutral, and how does it differ from a switched or solid neutral? I apoligize if I am a bit off topic, but in trying to figure out this picture I came across the term "overlapping neutral".
