    You need to supply us with much more information. Just for instance, what is the electrical load that will be carried by the conductors.

    Are you trying to set up a secondary panel to the first panel or are you building a new panel independent of the first panel.

    Yep, this is a weird question. Without more info it's hard.

    I do recommend that the panels power supplies be separate and only interface the panels with a contact closure.

    So if you want to turn on a light. A dry contact/relay goes in panel A

    Panel B contains the power supply for the LED and a relay. Panel B contains the power supply for LED in panel B.

    Don't power indicatiors directly from a panel far away.

    I know.

    Fire alarm and thermostat wire come to mind. Depending on the location, you may need plenum cable.

    Fire alarm cable is usually red with a PTFE insulation. Tstat cable is usually brown and should be available plenum rated.

    Make sure your contacts are driven at least at 10 mA
