I have a converter AC- DC and intend to power the building from transformer to building. Using the Menards connectors which I will cut at one end, Which wire is positive and which is negative. Second question, I would like to start the forklift action when a boxcar pulls into the siding. I intend to active this with an insolated rail or an IFR. I am not sure how to proceed since the building is DC and track power is AC. Would a relay be the answer? Thanks for your help.
