With the availability of large contactors up to 1000 A and breakers up to 6400 A, DOL starting can be used for LT motors of any size, say, up to 1000 h.p. The use of such large LT motors is, however, very rare, and is generally not recommended. Since large electrical installations are normally fed from an HT network, whether it is an industry, residential housing, an office or a commercial complex, DOL switching, even when... [Pg.71]

These receive power from the PCC and feed it to a number of load points, the majority of them being motors operating on an electrical installation or a process line. [Pg.336]

A similar danger of corrosion lies in cell formation in steel-concrete foundations (see Section 4.3). Such steel-concrete cells are today the most frequent cause of the increasing amount of premature damage at defects in the coating of new steel pipelines. The incidence of this type of cell formation is increased by the connection of potential-equalizing conductors in internal gas pipelines and domestic water pipelines [25], as well as by the increased use of reinforcing steel in concrete foundations for grounding electrical installations [26].
