I am looking to use suitcase connectors to connect my feeders (20 awg) to my bus (14 awg) and I want to make sure I use the correct size for the wires. It seems that all the available connectors are for sizes 18 awg to 14 awg and I want to know if these will work for 20 awg or is there somewhere I can buy connectors in the correct size - just too old to solder under the layout - thanks for the assistance
