MC connectors, warranties and PV system life [RE-wrenches]

[Tom Simko]

 Where appropiate I use aviation stainless steel saftey wire, its cheap and
lasts forever, and tied with the proper twist per inch (using special
aviation wire twisters) looks good. Of course potential abrasion issues need
to be taken into account when using it. Good for all around securing, its
available from any aviation mechanic or at any airport.
