Ring main for computers

[NoSparks]

Yes i agree.

Although isnt there a fair bit of earth leakage from the PSU??

Not really up on computers so be nice.

I won't say there isn't but I will say there should not be for two reasons. Fisrt, back in my collage days (many years ago) I designed a couple of temperature stabilisation circuits that used the same techinques as modern power supplies and those had no earth leakage, Second most (but I admit not all) lap tops have no earth! But who knows what cost cutting exercises bring with them.

Assuming thet we are talking T & E, and as this is computer terminals with high protective conductor currents, who does what and why for their method of earthing?

2 seperate earths seperately terminated in the sockets?
Does anyone run an additional earth

You tell me

i may be wrong but if you pull in seperate eaths with t&e you will create parallel paths which is not permitted i also try to keep the rings small if possible so as not to get more than 5 dbl skts on a ringl
keeping down the earth leakage but as someone eles mentioned with lcd monitors the problem isnt as big as with old monitors
