Currently I have my 3 main line,18x30 layout powered by 2 pw zw's in parallel with external breakers.feeds every 6 ft or so that all come back to a MTH power terminal.I bought a ZWC with 4 180w power bricks (want to expand layout)Is it time to divide my layout into power districts?Still not interested in running conventional even though the zwc lets you do that.going to add a fourth main line.Should I power each main line with a sep.brick?Thanks,Nick
