when we provide electrical connections to the server rack by industrial socket we need to remove the ELCB to avoid the trip , So
, any body know why???

Onsite Guide page 66. -7.6.1Earthing Requirements for the installation of equipment having high protective conductor current.
BrB . 543.7. 543.7.1.1 & 543.7.1.2.
I read the OP , as I understand no mention of tripping.Removing the device to avoid tripping ?
"we need to remove the ELCB to avoid the trip ." I then posted my references as a guide , and intrinsically earthing ,so at least the industrial plug would be fitted, & tested correctly.This should be a clean Earth Aswell.when we provide electrical connections to the server rack by industrial socket we need to remove the ELCB to avoid the trip , So, any body know why???
Murdoch , I don’t think that number of the users could affect.
Timbo_1975 , I agree with you , but how we can protect people when they use this very sensitive equipments?????
Malcolmsanford , yes, I mean residual current circuit breaker device but our contractors always keep name it ELCB and for A/C , they name it ELR and really I don’t know why but I asked them and they told me that ELR used when the A/C current exceed 100A, what do you think is it true??? Plz could you tell me what is the difference between all those terms , maybe the enclosure only different ???? Also, we didn’t measure the leakage current but the power supply tripped at 30mA and we installed only earth wire but I don’t think it is enough without any protective device , what do you think??????
High Tower , IT department are not flexible with our electrical department and not allowed us to test anything only what they want is removing of the protective device which is installed for their safety so I try a lot of solutions , one time I installed only the earth wire , and last time I installed isolator with the industrial outlet and connected to RCD = 300mA but still not sure that it is enough for their safety or not , however no tripping happened and IT people very happy!!!!!
Electro-tech , thanks a lot for the guides but our equipments exceed 30mA and tripped at 30mA so I replaced our RCD by 300mA , but is it safety to have 300mA???
