Leakage current of an iMac power supply
A switch mode power supply (by design) leaks current to the ground. The typical PC/iMac leaks about 3.5mA.
I have a an iMac 27" (late 2009 model) that leaks to the ground 5mA (I measured this), this is very high and would suggest faulty capacitors or another problem in the power supply.
My question is: should I try to replace the power supply?
An additional problem is that I have an office that was built in a residential apartment with a differential line breaker of 30mA (by regulation this is the rating in the EU and this cannot be changed). Since we have 7 iMacs in the office, the iMac 27" is making the differential line breaker trip. I tried to connect the iMac 27" to a plug without grounding and the result is an extremely unpleasant feeling of electricity when you touch the case.
Any idea on how can i solve this?
Is this a good question?
