Humm, I know I am only supposted to use Listed parts in my electrical assemblies, but hey, I know galvanized water pipe is the same as electrical conduit.... ....I find this thread somewhat disturbing in that it supports the idea of undermining manufactures requirements at the whim of the installer [just as long as you don't get caught by the inspector ;-)]. 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...

It's much less expensive, better quality, and does a tighter crimp than the MC tool. But.if you actually read the 4-page crimping instructions for MC4 connectors, Multi-Contact is highly specific that only their expensive tool is to be used. (On which they're making about a $200 profit per crimper.) Therefore, any cable ends assembled with the Rennsteig tool could be deemed non-NEC compliant. But really, when was the last time an inspector demanded to see the tool you used to produce your interconnect cables? I eventually won this battle. We're happy to offer a wide range of Rennsteig crimping, stripping, and cutting tools for MC4, MC3, and Tyco connectors, plus a selection of dies so one crimper can handle all the different connectors.

To use the MC4 locking connector from Multi-Contact, you need to use the MC4 crimper pliers. Multi-Contact wants almost $400 for one while distributor is asking for something close $500. However I did find one from a company called Rennsteig Tools out of Ohio. They're selling them for $225/each. Question: does anyone have experience with this particular tool and the MC4 connector? thanks, marco ProVision Solar, Inc.
