Earth leakage current

[BillP]

Hi,

I`m having 2 set of  Smart-UPS RT 10000VA 230V in my server room, its about 7 years old, and just did a health check with APC, said everything alright. I have RCCB protection for the UPS also, the frequency of RCCB trip is increased recently, I dont have  new device add in recently also.

At this moment, the tripping rate for RCCB is 100mA, can I check with you all, what is the maximum earth leakage current for this UPS? or is there any suggestion to prevent frequent trip on the RCCB?

Thanks,

Alex
