Kevin,
Believe it! The quality control on the wire solder job is not very good. If you run the motors (in practice) long enough to get the brush assy. hot, the wires do start to melt the solder. Since the connection is not a good mechanical one first, the connection series resistance rises as the solder melts making the problem worse. Sort of a domino effect.
Aidan, I am missing something. Table 5.2: Minimum Wire Size and Protection by Device Type in Section 5.6.2: Wire Size, lists the minimum wiring sizes for devices and controllers. Are you saying this is a guidline?
Newark has some superflexible wire that is zip cord #10, red paired with black, part # 24-1930 for the 100' roll, about $35/roll.
