  - the ratio of the load that a piece of equipment actually draws when it is in operation to the load it could draw (which we call full load). For example, an oversized motor - 20 hp - drives a constant 15 hp load whenever it is on. The motor load factor is then 15/20 = 75%. Use (or utilization) factor

  Feb 15, 2019 · However no more than two load transfers plus restoration from the source circuit-breaker (i.e. six switching operations) are acceptable (refer to Appendix A.1). Any network project should take into account these criteria and if they cannot be satisfied, this can be used to support the case for investment in network reconfiguration or reinforcement.
