Hope I'm in the right bit for this question

Just recently acquired a Megger PAT3 Tester which will be used for 110v leads / tools etc at work

Then the question came will it be able to test the office equipment - it will be ok for the kettle etc

BUT will it be ok for testing the Computers etc


thanks in advance

Martin
 
The PAT3 is an old, basic tester that IIRC has no leakage test capability, and only one earth bond test current. If you know what you are doing, a high current earth continuity test can often be applied to IT equipment, but if you make a mistake things can get fried.

Your risk assessment might indicate that the PAT3 is sufficient for your application, but even 20 years ago we expected more from a general-purpose PAT tester. I would not be happy sticking a pass label on a large photocopier without knowing its leakage current.

Thankyou for your reply

Looks like work will have to fork out a little bit more to get upto date
