(OP)
requesting information on proper motor lead to line connections. wire nuts, splice caps, splite lugs etc: code requirements or refference if available.

RE: motor lead to line connections

Depends upon the size, but for sure, wire nuts = NEVER! They are specifically precluded from any application that may involve vibration. That warning should be on the box label.

RE: motor lead to line connections

What I use for smaller motors are size orange Wirenuts(R), size yellow and size red Sctchloks(R). I use the kinds that DO NOT have wings so that I can tape the connector to the wires. In any situation where a wirenut or scotchlok is connecting stranded wires or is subject to vibration, you do need to tape them. I learned that the hard way back in kindergarten when grandfather was teaching how to wire light switches and outlets on breadboards. I did not follow his advice to tape up the wirenuts for the supply cord for the breadboard and got my fingers burned. After that I followed grandfather's advice religiously.

RE: motor lead to line connections

I am not aware of any actual code requirement where you have to use a specific type of cable splice for motor lead to supply line connections. I do not like to use wire nuts, but if I have to because of motor location or space restrictions etc. I always tape them. I prefer to use split bolt and tape or crimped on wire lugs with a round hole. Using a proper size bolt with flat and lock washers you will get an excellent connection. Make sure to use a good quality tape, the best method is to apply a few wraps of rubber tape covered by several layers of plastic tape
