You haven't mentioned if they are stranded or not. Assuming they are
stranded, then there is no LOGICAL reason why you cannot do this,
providing the total wire bundle's combined size does not exceed the AWG
range of the terminal. After all, how would the connector "know" which,
and how many, strands came from what bundle?
However, standards bodies are not always known for their ability to
apply logic, so whether this is actually approved is another matter. If
they are solid wires, then the situation may also be different.

Subject: NEC Wiring Question
Greetings all,
An issue came up in a product 61010 safety evaluation and no one here
can remember if you can / can't do it.
Does anyone out in Cyberland know if the NEC allows 2 wires of different
sizes (awg) to be clamped together in a clamping type PC mounted wiring
terminal.
The wire is striped bare & inserted into a slot on the side of a
terminal block that has a screw on top for tightening.
I seem to remember the code does not allow wires of different gauges to
be clamped together under a single compression clamping terminal.
I have searched the NEC and can't find anything on this.
Can anyone remember chapter & verse on this issue.
If I'm wrong, please be kind, the 60 hour weeks are getting to us.
Thanks in advance
