Dana, How does one upgrade the chip? I couldn't find that info on the CI website.

It has the current NEC code built in, an upgradeable chip for the next current code , so no need to replace the calculator when code changes.   You can affect : %VD, Wire size, Length, amps, volts, raceway mode, Temp, power factor, Phase, ground, conduit size, watt, O-load, HP motor size, on and on.   I have used this for 10+ years [ I am guessing]  and it allows you to instantly look at so many options in just a few key strokes. Esp. great when trying to straighten out someone else’s mess and show a client on the spot where the errors are and how wonderful, &  knowledgeable you are and that they need you. This is one tool that I consider to be indispensable. There is one in my truck bag & one on the desk.   There are a lot of handy tools in my bag but this is right there with a great set of screw drivers, line-mans pliers,  wire cutter/trimmers, etc.   www.calculated.com   800.854.8075   Dana Orzel Great Solar Works, Inc E - d...@solarwork.com V - 970.626.5253 F - 970.626.4140 C - 970.209.4076 web - www.solarwork.com   "Responsible Technologies for Responsible People since 1988" Do not ever believe anything, but seriously trust through action.   From: re-wrenches-boun...@lists.re-wrenches.org [mailto:re-wrenches-boun...@lists.re-wrenches.org] On Behalf Of Starlight Solar, Larry Crutcher Sent: Wednesday, February 02, 2011 9:00 AM To: RE-wrenches Subject: [RE-wrenches] Parallel wire runs to increase size   Wrenches,   Some of our business involves repairing poor PV solar installations on recreational vehicles. So often we wind up installing a roof junction box and running a second PV to controller wire and then replacing the controller to battery wire size. For instance, we may find a 10 gauge wire run to the controller. We then add #8, #6, #4 or even 2 gauge and parallel to the #10 depending on power and distance of the run. My question: Is there a calculator or chart that will tell me what the combination of any two wire sizes equate to? example: #10 + #4 = X   Thanks.
