[Source: Shutterstock] For maintenance managers, spare parts inventory management is often an afterthought. In some cases, it is not even considered until an unforeseen incident occurs. Moreover, as companies grow, critical spare parts management becomes more complex. Over time the proportion of inactive spare parts inventory grows in comparison to the working stock. If there […]
Under overload conditions, both selective and cascading circuit breakers systems are selective, with only the breaker nearest the fault tripping. The difference is under short circuit conditions. Selectivity Circuit breaker selectivity minimises the impact of electrical faults by ensuring that only the downstream breaker closest to the fault trips. This preserves continuity of power for […]
Circuit breakers in a distribution system will trip in the event of a fault and protect the cables. Circuit breaker selectivity ensures coordination between protective devices so that when faults occur, power continues to all other parts of the electrical installation. The use of circuit breakers has grown as they enable swift identification of the […]
A short circuit in a power distribution board can cause immense damage to the equipment and shutdown processes for weeks. This is important as OEMs and panel builders need to consider short circuit capacity for industrial operations while using less energy and space. According to Schneider Electric, more customers are asking for control and electrical […]
Before miniature circuit breakers, fuse distribution boards provided cable protection for electrical circuits. They worked well and continue in use for some applications. The biggest drawback was that in the event of an overcurrent or short circuit, the fuses needed replacing. Furthermore, it took time to find the electrical engineer and meant a wide […]
