Re: Protecting bus to feeder connections

Al Silverstein

There are several methods used to connect feeders to bus wires: the two that seem most common is the soldering of the feeder to the bus and the other is using a “Tee” connector to connect the feeder to the bus. You need to be careful in both cases to insure a good connection. Poor solder connections can cause trouble while improper “Tee” connector can cause a poor connection. Good tools are required in both cases to insure a good connection.
I use stranded 14 awg wire for my main bus. It works for me as none of my bus runs are more than 20’ from a booster or the command station.
I use solid 22 awg wire for my feeders. Keep in mind I am a N scale model railroader.
I purchased a tool the opens and spreads the insulation on the wire bus. I use a wire stripper to strip the feeder. I remove enough insulation so that I can wrap the feeder wire around the bus at least twice. I then carefully solder the connection using a temperature controlled soldering iron. When the connection cools I use red or black finger nail polish to seal the connection.
The above works for me.

I am new to DCC, although I have been accumulating 'stuff' for 20 years - HO scale, so I have lots of questions, most pretty basic.  Since the bus to feeder connection is a 'T' and precludes the use of shrink tubing, is liquid electrical tape appropriate for this use?  Do most of you use some form of protection for this solder junction?
