Cat6/Cat6A - Data/Ethernet and power line next to it

Dear All,

Thanks in advance,

I know that it is not advisable to run Cat6/Cat6A - Data/Ethernet and power lines side by side though i want to ask how rational we could be with this.

​

Is there any formula to calculate the risk?

​

for this case there would be a Cat6/Cat6A UTP running 2-3 Inches away from the power line where power would be drawn at 60 watts max and it is from the UPS so no fluctuation would be there.

while some very low power motor would be attached through this power line in very few cases but i want to make sure if it is a good idea or not.

By standards it is not acceptable i guess while from thumb rule or experience there would be no issues whatsoever, is it true?
