I completed a major infrastructure project last night - installing a power / control bus and feeders to the rail. Up until this time, I simply had the command station attached to the rail in one place. I chose to solder the feeders to the bus. When attached in this way, is it typical to insulate this connection? While I don't mind soldering to the bus (although stripping is a pain), I'm certainly willing to try a "tap" into the bus. Are there taps that will accomodate a 12ga. bus and 22 - 24 guage feeders? The ones I've typicaly don't have such a large difference between the "tapped" and feeder side. Thanks.
