Line Voltage Disconnect Box

Use a line disconnect box for each power supply so that the operator can turn the power supply off
quickly in an emergency situation. Locate the switch near the power supply so that it is easily
accessible to the operator. The interrupt level of the switch must be equal to or exceed the continu-
ous rating of the fuses. Use slow-blow fuses as listed below.
