I had to disconnect the motor leads from the incoming AC power on my dust collector (Oneida 2.5hp SG). The pigtails were crimp connected together using pre insulated closed ended crimp connectors (link to data sheet). Since they were crimped, I had to cut them off. Whomever wired this originally, used a too small connector. The Ideal model 49 connectors used are not sized for 3 - 14AWG wires (which is what I need).

My question is what is everyone else using to wire motor leads? I have to special order the correct size connectors with a minimum quantity of 1000. Something I is really unacceptable. Should I use crimp on ring lug connectors and tape them? Wire nuts are not particularly vibration resistant, but they are inexpensive.

Thanks...
