Jimbo1952 said, " B. Alternative Option for Feeder to Bus Line: Wago 221-413 which is the 3-conductor splicing connector. This is also approved for both solid and stranded wire and 24 to 12 Gauge wiring. In this case, I’d have to actually cut the bus line in each instance and there will be one conductor for “bus-in” and another for “bus-out” and the third for the feeder. This would seem not to be ideal with possible power loss due to repeated cutting of the bus line. But maybe there is no appreciable power loss and this is better/easier than utilizing the Posi-Tap Connector arrangement."
If you go to the Wago website for technical data you will see that the losses and/or resistance through their connectors is negligible. I've used their connector for bus feeds, grounds and accessory feeds with no noticeable losses. Yes, the great advantage is you can remove the 3 way connector and install a 5 way to give you additional ports. Very much flexibility with this style connector, just make sure it has the Wago logo on it and is not a knock off. Good luck.
