The command station has a 5 amp booster.  NCE says to run a ground between the command station and all boosters (connecting to a screw on the bottom of the box).  But what should I do with the ground wires coming from the 5 amp power sources needed for the 105 and command station?  This is not the 110volt plug wire.  From the power source there are 3 wires- two screw into the booster, plus there is a ground.  Does this ground need to be attached somewhere?  The pb5 with the built in power source has no ground wire, so I guess it just needs a wire connected to the 105 and command station.

Bob,
You can verify if the actual ground prong on the 120Vac power plug is connected to the PB5 booster case or not with a simple ohmmeter check. Does the NCE command station also have an internal booster with a DCC track output? If so the case of that unit needs to be bonded to the cases of the PB105 and PB5.
