TMCC/Legacy base transformer plugs

Definitely can’t use the Legacy power supply to power the standard TMCC base.

THIS power supply will work

Zach,

A regular 2 wired spaded plug with the 3rd wire going to earth ground which is the screw on the outlet cover? I remember the OGR post.  

That Power supply actually has a ground pin, so you would run AC+ to the center of a barrel jack and the AC - to the outside then at the power supply jump the AC - to the GND pin

EDIT: I can't remember if the power supply specifies what AC line is what but it really wont matter as long as the outside jacket to the barrel jack also goes to ground

Ted,

Check out this thread for details on a jumper to convert a standard wall wart into a grounded one:

I like Zachariah's solution, just jumper the ground to the outside barrel connection and you're off to the races.  Do remember that the power connector is the 2.5/5.5mm connector and not the more common 2.1/5.5mm connector.
