OK, a few would be 356.30,334.30,250.119,250.144,310.12(C) all 2008 NEC
If you paid for that install you have allready been raked.


I do appreciate the specifics and have finally had a a chance to correct them.


356.30 The loose conduits were from the generator to the transfer box and not yet attached to the wall. That is now done.

334.30 The NM cable goes to a subpanel for 6 circuits in the basement. The project was never completed but obviously the existing wires should have been attached to the wall.

250.119 It is odd that the grounds were not covered with green tape when the house was built as that was part of the original wiring in 1991. They are both now covered with 3M green electrical tape.

250.144 I am really not sure what this is referring to, can you explain?

310.12 refers to color coding ungrounded conductors. All of these were 240 circuits where Black and white conductors were used. I colored all of the white conductors red.

Since this has also been like this since the house was built and did pass inspection, did the 1991 code have the color requirements or was this something the inspector just let go?


Thank you for your help.

250.144 Multiple Circuit Connections. Where equipment
is grounded and is supplied by separate connection to more
than one circuit or grounded premises wiring system, an
equipment grounding conductor termination shall be provided
for each such connection as specified in 250.134 and 250.138.


This is in reference to all of the EGC twisted together and landed under on terminal. The terminal could be a violation depending on the mfg. instruction as to the number of wires that can be terminated under that screw.
As far as the color coding. Yes, that is probably one of the most overlooked and unenforced violations in the code.

Thank you that makes sense now. When I unbond the neutral from ground in this panel I can untwist them and connect them individually into a ground bus attached to the case. My only question would be is there any regulations where the ground bus has to go. There are holes on the lower sides of the load center that I assume are designed for a ground bar but the ground wires will never reach that point. Is there any reason I could not put two ground connection strips one on each side of the main breaker next to where the ground wires are now twisted together?

Yes, you can put it any where just remove the paint. You can also use wire nuts and extend the grounds to reach the buss.

Ok pretty much done.
I added two ground bars and ran all of the grounds to them.
Today I finished up the main wiring, new SER from the meter to the transfer switch and 2/0 wire from the transfer switch to the load center. Unbonded the load center grounds from neutral as well.

Thanks to all that helped. Putting in the RTS transfer switch was much more work than the installing the easy switch with selected circuits to run during a power outage.

Additional pictures added. If you see any issues please let me know.

Thanks again.

GET THE NEUTRIAL WITH THE PHASE CONDUCTORS IN THE SAME CONDUIT TO THE PANEL NOW!!!!!

I would also mark the neutral conductor with white tape everywhere it goes into or out of conduits. I don't think that's a requirement, but it surely makes it easier to see where things are run.

Is that a code requierment? The reason I did it the way you see it is the large conduit that I had is 1 1/4" which is only supposed to hold 2 2/0 cables. So I ran the 2/0 ground through a piece of 1" conduit.

Thanks again for the input.

Yes, it is a code thing but more importantly you are going to have a MELT down with your wires. The neutral must be ran with the phase conductors to counteract the electrical magnetic field between the phase conductors. The only thing saving you now is you did run the EGC with the phase conductors but it is not enough.

Thank you. I will change that tomorrow.

Don't put it off. You could just run SER cable from the ATS to the panel. How ever you decide just do it.

Changed the 1 1/4" conduit to 1 1/2" PVC and ran all three 2/0 power wires and the ground through it.

Thanks again.
