The only true ground on an o-gauge layout is the earth ground on a TMCC equipped layout[used for a "ground plane" to overcome TMCC signal problems but --NOT connected to track any where, at anytime!
The little wall wart transformer of the TMCC Command Base connects to the earth ground of the household circuitry and is offered at the #5 pin on the serial port of the COMM Base to receive a DB-9 connector and wire run to certain TMCC control modules[TPC,ASC,etc]. Under no circumstance would you connect the #5's pin or wire run of earth ground to the layout's common return or to track--never!
The use of "ground" in describing the o-gauge common return has unfortunately become "common" usage. However, they are not even double first cousins. One is a electrical return conductor and the other is a true earth ground.
Thanks Dewey,
I am slowly coming to the conclusion that I am going to have to greatly reduce my involvement in the electrical forum . It seems that there is an over abundance of shade tree mechanics that don't want to wire things correctly and safely they just want to get it done and are more than eager to impart that misgiven knowledge to those that don't know any better.
They obviously don't work in this industry and give definitions that are obviously wrong. I won't take part in a forum that continuously encourages those that think they know what they're doing but don't have a clue who have no certification other than their self attained knowledge.
And continuously give input to the unknowing that will cause problems down the road
I was a big advocate of the inception of the electrical forum. I felt it would be a great thing for me to be able to help those just getting started to save them money and disappointment when they burned something up because they had no one to tell them how.
It's not just this thread but the majority of the threads I've participated in that it's been this way.
Thanks again Dewey it's nice to read a post from someone I know ,knows what they're talking about....Later
David
