We decided that we would run one wire from each of our four drive motors through the project box and use the resistance in 5" of the #10 conductor. It then occured to us that extending wires out of the project box did not violate the rules. Therfore, we could use the entire length of the black conductor from each motor speed controller and apply the 0-5vdc (0-100Amps) against thermal models on the 30Amp thermals and collectively against the 60 amp main breaker. We are thniking of applying the 0-5vdc directly to an RC circuit for the thermal model. We are open to suggestions. We have less than half of the technical people we had last year, so we are short on the most important resources, people. We have also not recieved any of the materials from Small Parts that we really needed.

Well, you might try measuring across the breaker itself. We do it, and it works real nice.....and it makes the wiring nice and short. (you do have to build a "Y" connection at one end of the breaker though....but this is no big deal)
