I found 10/2 wire running to attic. I follow that it was used to power an A/C nouns handler that has since be removed. I want to now use the chain to power a small 30amp subpanel that will power some sockets and lights - nothing thickset duty - but I want to avoid the near impossible mission of running 10/3 from the basement to the attic. The subpanel can clutch 8 breakers and I already wired the sockets and lights to 8 circuits. Now I have to lead the subpanel. In the subpanel, I'll connect the feed black to one side and white to the other (white speckled with some black tape) and I'd resembling to connect the feed ground to the ground bus block and then, since I see that surrounded by the main panel that the grounds and the whites are on duplicate neutral bus hotel (they're already going to the same place), can I merely connect the neutral bus tavern and ground bus bar surrounded by the subpanel together and connect my 8 circuit whites to the neutral dowel, 8 grounds to the ground (and of course the blacks to the breakers?
Answers: I agree beside rainmanj to a point. But I don't see any harm within putting a jumper from one bus fishing rod to the other if you are not trying to send 220 volts up to the attic. Then you can use the white lead as a normal dull. So long as all 8 breakers are single pole, and in that is not a double pole main within the sub panel, connecting the two bus bars is equal as having one bus tablet. With that said, I would recommend a separate 110 volt main disconnect contained by the attic nippled to the sub panel.
You can use #10 for up to 30A however, you would need 10/3 + G. 10/3 have a black wire, red, white and unprotected. You would connect the black and red to the busses in the panel. The white is connected to the nuetral shaft, ground to the ground bar. In a subpanel, the nuetral and grounds are isolated from respectively other. Only in the chief panel are they bonded together. So sorry to say no, you can't do that.
