Re: [RE-wrenches] Small Torque Wrench

[r...@solarray.com]

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.

We’re talking 1.1 to 3.3 N-m (10-30 in-lbs). I’m imagining something compact like an over-sized screwdriver.   - Peter Please note new e-mail address and domain: William Miller Miller Solar Voice :805-438-5600     Fax: 805-438-4607        email: will...@millersolar.com http://millersolar.com License No. C-10-773985 _______________________________________________ List sponsored by Home Power magazine List Address: RE-wrenches@lists.re-wrenches.org Options & settings: http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org List-Archive: http://lists.re-wrenches.org/pipermail/re-wrenches-re-wrenches.org List rules & etiquette: www.re-wrenches.org/etiquette.htm Check out participant bios: www.members.re-wrenches.org
