PC earth leakage

PC earth leakage

PC earth leakage

(OP)
Does anyone have an idea what the expected rang would be for leakage to earth from a standard desktop PC?

RE: PC earth leakage

(OP)
Thanks for the input. UK requirements are such that if a power circuit is protected by an earth leakage detection device (i.e RCD or RCBO), the maximum cumulative leakage current for equipment connected to this circuit must be calculated. I would like to get a feel for what typically could be expected when connecting computers to a circuit, hence the question.

RE: PC earth leakage

I don't know. If you can't measure directly, you may need to consult a PC manufacturer to get typical data.

RE: PC earth leakage

Suggestion: Please, notice that the computers supposed to have two different grounds, namely, the equipment ground and isolated ground. The equipment ground can get contaminated with various waves, i.e. becomes "noisy" that is harmful to electronics.

RE: PC earth leakage

(OP)
Once again thank you for the comments. Obtaining any info on this from the PC manufacturers is difficult. I may have to physically measure it on several old and new PC's to obtain a range.
