When installing a small loadcenter off of a panel, and there is only a neutral bus, when do you install the green bonding screw? Also, do you also pull a equipment grounding conductor to the same neutral bus? I need a refresher on this. Thanks.
 
Welcome to the forum. The neutral and EGC can terminate on the same bus in the service panel. These would have to terminate on separate buses in the subpanel.
 
et: I wasn't clear if you had both a grounded (neutral) and equipment grounding conductor. If you have no neural or need for one, the "neutral bar" with a bond screw can be used as equipment ground. That is real common in subpanels for HVAC equipment with only 240 volt loads.
It is fairly common here to see that bar used as a ground and the neutral wire-nutted where there is limited neutral load (such as one outlet).
As infinity said, the primary rule to reacll is no connection between grounded and grounding after you leave the service panel.
