We have kind of a strange 12-Lead motor where the leads aren't your typical 12-Lead arrangement or markings. It appears that each phase has (4) leads with each of the 4 leads per phase marked T1, T2, T3. The datasheet shows the motor internally being wired in Delta. I'm not sure why each lead has multiple parallel leads, but I'm assuing its so that one large lead for each phase didnt have to be brought out. This is a VFD motor.
To this motor we are running a parallel set of 500MCM feeders. My question is this:
If we terminate the 4 motor leads for each phase with the two parallel 500's for each phase this will be a rather large termination point and be rather difficult to do with a split bolt etc... Are we able to take to of the motor leads for a phase and terminate them to one of the 500 phases, and take the other two leads for the motor phase and terminate them to the other 500MCM phases?
I dont know what the code says about terminating parallel feeders to this motor application, or what downsides there are for doing this.
