Generator Transfer Switch Question
I recently installed a portable backup generator with a Reliance ProTran Q 510 transfer switch. Everything works great, except I had a question about how I installed it. My home has a 400 amp service with two 200 amp main panels in the house. There were some circuits in the first panel and some circuits in the second panel. The transfer switch comes with a black and red for each circuit and only one white and one green for all the circuits. I installed the green and white to their respective bus bars in the first 200 amp panel. Then I ran a conduit between the two panels and ran the red and black cables from the transfer switch to the second 200 amp panel. I did not bring over the white and green wire from the first panel to the second. The second panel was already tied to the first panel with a big copper ground wire.
So my question is: Is this legal and safe? I thought it was because the neutral and ground are bonded at the panel. And I thought the neutral/ground in one panel is the same as the neutral/ground in the other panel. All my circuits, whether on generator or main line check out with a line tester. I just want to make sure I'm not overloading the neutral and I'm not creating an unsafe situation.
Thank you for any feedback.
