Funny this subject came up -- we just had two terminals in the AC
terminal block of a VFX spin out before reaching the 30 in/lb spec.
OutBack customer support has been great so far -- they're sending us a
new replacement. Personally, I've never used the torque screwdriver on
the OB AC terminals. I just trust my wrist. Another tech (NABCEP) in
our shop tried to take them to spec, and this is what happened. It's a
double stacked system, and the other inverter's terminals reached the
torque spec just fine. Seems like a faulty terminal block. Is the
torque spec too high? 30 in/lb is a lot for small terminals like that.<br>

Reviewing Outback and Xantrex manuals, screw terminals are torqued
between 14 and 35 inch pounds on these electronic devices. This
should help your search for the proper tool.<br>

have a great torque wrench for snugging down module clamps, Sharp SRS
bolts, etc. What do folks use to insure that wire terminals are torqued
to spec? We’re talking 1.1 to 3.3 N-m (10-30 in-lbs). I’m imagining
something compact like an over-sized screwdriver. <br>
