8-6. Insulation Tests
On completion of disassembly and repair, measure the insulation resistance, and conduct the dielectric strength
test.
Insulation resistance: After switch is turned on, more than 10 M Ω by 500 V DC megohm meter between live
parts and accessible metal parts.
Dielectric strength: After switch is turned on, there must be no trouble when the voltage indicated below is
provided between live parts and accessible metal parts.
Less than 150 V of rated voltage: 3,000 V x 3 sec.
More than 150 V of rated voltage: 4,400 V x 3 sec.
8-7. No-load Current Value
After no-load operation for 30 minutes, the no-load current value should be as follows.
Voltage (V)
Current (A) max.
110
8.0
220
