    Default Power Feed on LOR Board

    I am wiring LOR boards trying to finish up everything and all I have left is to put the power feeds on the board, seeing that I am not using alot of power per unit when I wire it I intend to wire each board with a single power feed. My question is I know you must bridge sides for the hot feed to supply power to both halfs but do you have to bridge neutral or is the neutral section of the board tied together?

    You also need to bridge the neutrals also. Each side of the board is independent of the other.

    By design, this allows two different voltages to operate at the same time on each board.

    For example, one side could be 120 volts AC and the other side 24 volts AC.

    So bridge both the hots and the neutrals. The PC boards have an extra neutral lug on each side for this purpose.

    I also bridge the grounds (heat sinks) - they aren't electrically connected to each other. That's probably overkill, but if I can provide any path to ground for any surges other than through the board/cables/computer, I will do my best to do so.

    I have never heard of this, does anyone else do this? It makes sense to me.

    Yes, I do. Almost all of my controllers are wired for only a single power feed since I use almost all LEDs

    I do if feeding the board with 14-16-18 w/ground. But I usually just use SPT wire for my power inputs, so I don't have grounds.

    Very interesting, So when "bridging the heat sinks" do you drill a hole in the aluminum heat sink and use a small bolt and nut to connect the wire?

    No, I use a round crimp-on and just put it under one of the mounting screws for the heat sink going into the case, running the jumper over to a mounting screw on the other side. Holes are already there, no need to drill more.
