Hi,
About 2 weeks ago fitted a new 58W tube Fluroescent light fitting (£12 from B&Q). The starter has just failed on it, is this likely to be a faulty starter or could there be some other fault?

Hi All,
Here is the scenario that I have.
3 Phase, 690 Volt Motor (Delta), 560 kW and started by a star-delta starter. So the motor is connected in delta at full voltage 690 Volts after the chageover from star.
Now, this motor has failed and is beyond repair, and lead time is considerable for...

He’s sent a drawing but it’s that old it’s like trying to piece the dead sea scrolls back together...

When testing Insulation Resistance or Continutiy on a 3phase Motor, do you need to disconnect the cables from the motor?
Or do you just test I.R to the starter, then I.R from starter to motor? (as the starter will be open when dead)
Would a motor come under "equipment vulnerable to testing"...

Hi all
