INSULATION RESISTANCE READINGS
Normal Ohm and Megohm Values between all leads and ground
Condition of Motor and Leads Ohm Value Megohm Value
A new motor (without drop cable). 20,000,000 (or more) 20 (or more)
A used motor which can be reinstalled in well. 10,000,000 (or more) 10 (or more)
Motor in well. Readings are for drop cable plus motor.
New motor. 2,000,000 (or more) 2 (or more)
Motor in good condition. 500,000 - 2,000,000 .5 - 2
Insulation damage, locate and repair. Less than 500,000 Less than .5
Insulation resistance varies very little with rating. Motors of all HP, voltage and phase ratings have similar values of
insulation resistance.
Insulation resistance values above are based on readings taken with a megohmmeter with a 500V DC output.
Readings may vary using a lower voltage ohmmeter, consult factory if readings are in question.
