If it is a motor connection that is being tested, engineers like to see it above 5 meg. In reality above 2 meg is fine.
The term is 'megger', not 'mega', and the answer is infinity.
It reads 100, 250 1,000 DC for both 200MΩ and 2000MΩ ranges.
I did them with a 1,000 volt megger .
Megger Group Limited was created in 1889.
if check voltage is 2000v then acceptable range is 400
100

The value of insulation resistance varies according to the type of CT and manufacturer. It is best to check with the manufacturer for acceptable values. The word 'Megger' is a registered trademark of Megger Limited. Megger Limited's product range includes insulation testers, relay testers, battery testers and many other electrical test and measurement products. Tony Wills, Applications Engineer, Megger Ltd.
A number is meaningless without units.
What is the acepable rating on a #3 wire when meggering @1000v
It reads 100, 250 1,000 DC for both 200MΩ and 2000MΩ ranges.
It is measurement done by megger tool of measurement .
It depends on what you're measuring.
what is difference between phase voltage 415volt and 440volt
You can, and you will get a reading if the leakage is within the operating parameters of the megger or there is a dead short in the windings. Most larger voltage motors need higher testing voltages. A hi-pot tester will deliver these higher voltages.
