Hi: I posted below but my question wasn't clear.

I'm left with a 6/2 + ground wire to finish the basement. I'll use a 60 amp breaker at main house panel to supply a subpanel.

There is a need for 3 ea. 20 amp. circuits (loads already calculated). No 240v service is needed/wanted.

The question is: how are the connections between panels done?, specifically the neutral and ground wires. House is frame type.

Thanks Billhart for previous answer.

It is best to put the reply in the orginal thread so that I can refer to the background informaion.

First at the "main panel" it might not be the service entrance. In some areas or house layouts there is a disconnect by the meter and that is the "main" and the main panel is in fact a sub-panel.

But connect the neutral to the bus where the other neutrals are connected and the ground to the ground bus where the other grounds are connected. Maybe the the same or may be different busses.

At the basement sub-panel you have to isolate the two busses.

"At the sub, hot to the hot bus bar, neutral to the neutral bus bar (which is isolated from the enclosure)and ground to the enclosure itself?"

Here is my reply from the first thread.

"You will need to get a ground bus bar kit.

You need a place for not only the ground wire from the main, but also the ground of all of the loads."

Panel busses vary. Some have two busses with a strap between them. Remove the strap (or in some cases 1/2 of it) and you will have an isolated bus (neutral) and a bus bar directly monuted on the case. That is the ground bus bar.

Other has bus bar with green bonding screw. Remove that scew and the bus is isolated from the case and is used for neutral connections, but from the feeder and the loads.

Then you get a ground bus bar kit for you panel. It mounts directly on the metal case and is ued to attach the ground wires from both the feeder cable and the load grounds.
