Proper wire sizes, etc. Arild I may be in error, but I honestly don't remember any mention of wire sizes, only the business of connecting a smaller wire to a larger wire. So I responded accordingly. Without stating the capacities of the wires mentioned, I believe I was correct in my statements. As for overhead distribution wires, some times you see them with insulation, particularly low voltage service drops where the wires are run parallel and close together. The higher voltage wires at the top of the poles, being way out of reach and far apart, do not require insulation, are cheaper to install without insulation, and yes, they may tend to run cooler as a side effect. As for the sensibility of my previous statement that you quoted, please tell me where I am wrong to state that the wire size should be commensurate with the breaker rating. The wire size as you and I both stated can be larger than required for simply carrying a certain number of amps for voltage drop reduction. Going the other way below the current capacity of the supply circuit is a no, no! With your clarification of my alleged rebuttal, which was really just my comments on the situation, I understand better where you were coming from, and we have no disagreement. The rest of your response is pretty good and I am in general agreement with your statements. Russ Hughes Slo-N-Easy Richland, Wa.
