Routine test:
Manufacturer should have following mandatory test facilities for routine tests at his
shop.
1. High voltage test.
2. Full current injection test – AC current equal to designed motor starting
current should be injected in to FCMA coils for time equal to starting time.
3. Insulation resistance test.
Performance Tests:
Manufacturer should prove the motor starting current on the site as guaranteed by
measuring the same with analog tong-tester.
Timer:
Knob type electro-pneumatic time delay relay range 0-60 sec. It shall conform to
IEC.337-1-1970 or IS:5834 Part I, convertible from ON delay to OFF delay or vice
versa, suitable for 110 VAC 50 Hz rating, 1.5 Amps, terminal capacity for 2.5 mm 2
copper control wire, with 1 No + 1 NC.
Isolating Switches
Isolating switches shall be on load double break type and shall have suitable current
and voltage ratings. The “ON” and “OFF” position shall be clearly marked.
Isolators used for motor control circuits shall be of motor cut type, capable of
carrying the starting current of the motor.
Fuses and Fuse Carrier:
All fuses shall be HRC cartridge type conforming to IS:13703, mounted on plug-in
type fuse bases. All accessible line connections to fuse base shall be adequately
shrouded. The fuses shall have operation indicators for indicating blown fuse
condition. The fuse and fuse carrier shall be suitably selected for rated and fault
currents. The fuse for motor control circuits shall be so selected that the same shall
not operate during motor starting.
