Double Bus Bar Panel

The side panel illustrates a double bus bar panel generally one designated for electricity authority supplies and the other for the in house generator supplies. The above panel has an ACB incomer and inter locked contactor selection of the bus (DG or EB) having the common end supplying the load. The very special feature of a double bus bar arrangement is to use electrical authority supply and generator at the same time. This helps in putting certain special machines’ on DG and the others to run on general supply. The bus could be supplied by one or more generators either synchronised or segregated by bus couplers. Though this system is quite costly wherever uninterrupted supply is needed this system scores.

This uses manual changeover switches or MCCB/ACB combinations to select buses. These change over though are manual, can be offered as remote Controls also.
