      Need drawing for a manual changeover panel fed by 2 generators using only 3 manual changeover switches and interlocks if necessary to connect 2 loads in such a way that any of the genset could feed any of the two loads.
      Generator1 should feed either load 1 or load 2 and generator 2 should feed either load 1 or load 2. One of the generators need not feed both loads at the same time but both loads should be fed at the same time using one generator for one load only.

          Thanks. How to do it with single set of contacts in each of three changeover switches was my question.

            Thanks. Can you give web addresses of some suppliers of the multiple contact manual changeovers?. Further please give a diagram if the third source(the utility)is included. When the utility is available generators need not operate.
