My current, temporary loop is FastTrack, and one of the connection tracks has mighty small track wires, coming out of it, to connect to. That is the connection on one end, and I have heavier wire going across to the other end and connected to a barrel with 16ga pigtales. The wires from the barrel connectors to the contacts in the track, seem small as well.
