Uhm. not quite. The insistence of MC to use their tool has nothing to do with code, NEC, UL, or anything else.
It has to do with (1) sales, (2) liability, and (3) quality control. For (2) it means that if a connector fails, burns down the house, and kills 93 chickens that they are not liable because you did not use their tool. For (3) There are or at least have been in the past attempts to use crimping tools that were totally not meant for MC connectors, and there was also at least one junky Chinese(?) knockoff that was way out of spec. ..................................................................................................

Scroll up a few post and find folks singing the praise of inverter manufacturers, confirming the need to strictly abide by their requirements as documented.... ...this willingness to subvert clearly stated manufacturer requirements for the sack of a few hundred bucks peals off the vanier of emerging maturity and reveals the underlying backwards-ness inherent in the PV industry...
