The answer of manish joshi is correct some correction as follows
1. RTD's: Resistance temperature Detectors : used to
measure the winding temperature , PT-100(2mA) is used in RTD
and
normally 6Nos can be used(In each winding 2nos RTD)
2. BTD's: Used to measure the bearing Temperature rise.
Normally 1pc/Bearing (In each side 2RTD used Drive side end
(BE) & non drive side end(NDE))the total 4RTD required
3. DTT's : Dial type thermometeres with contacts/without
contacts alarm trip.(DTT normally used for drive side end &
non Drive side end at max 250v,5A)
4. Space Heater: Used to remove moisture when motor starts
after a very long time where moisure is present in the
surroundings. ratings 240 V 1Ph.
5. SPM Nipples: for vibration monitoring (for drive & Non
Drive Side end)
6.Seperate terminal box for space heater(1ph,240v,300w).
7.Greasing Nipple for Drive & Non drive End.
8.Vibrating Sensor at drive side.
9.Main Terminal box to coonect the supply 415V AC.
10 Neutral terminal Box if required
11.Lifting Hook to lift the motor
12.Earting Bolt as per your electrical system.

What is the practical way to calculate the cable size for known ampere load?
what is a power factor?
In Air circuit breaker LSIG protection unit is used. Without fault in cables (2 runs 3Cx150Sq.mm Copper, 1Kv grade, XPLE armored cable IR value is more than 550Mohm @ 500V Megger) and load section Long time Overcurrent protection is triggers and trips the unit. We changed LSIG protection with new factory tested unit. Even then fault is persisting. Please suggest the possible causes
