Summary

Switches and other control or protective equipment should be very convenient to the operator; no other part of the station installation is used so often during operation and in emergencies. Although accidental operation may cause serious danger to service, to operators, and to equipment, it can be practically eliminated through careful design and arrangement of control and protective equipment. For station operation, it is not always practical to enclose fuses or circuit breakers in cabinets, as it usually is for utilization equipment. Severe burns and eye flashes are not uncommon and must be considered when handling such appliances. The installation of a suitable switch provides the means for disconnecting equipment and circuits entirely from the source of electrical supply. Except for fuses at low voltages, removing fuses from exposed live clips or other contacts generally is dangerous.
