How are bus plugs selected?
What will be an ideal response?
The bus plugs provide branch-circuit protection for each of the machines and must be selected according to the specific requirements of the individual machines. One advantage of the fusible plug-in unit is that a minimum number of sizes are needed. The plug-in unit size is based on the switch ampere rating. In addition, the protective device rating can be easily changed. Where such devices are located out of reach of the machine operators, suitable means must be provided for operating the disconnect means.
