Inrush current limiter is an electrical part that was used even in 1950 televisions. Many confuse it with an MOV. Examples: http://www.alliedelec.com/search/searchresults.aspx?dsNav=Ntk:Primary|inrush+current+limiter|3|,Ny:True,Ro:0&dsDimensionSearch=D:inrush+current+limiter These...

Critical is not protectors. But how those protectors connect to earth. Not earth that is only a 'safety ground' (ie a receptacle). Earth that is an electrode in the ground. Critical to making that protector effective is even wire length, as short as possible (ie 'less than 3 meters'), to...

And again, this is why bettter installations also have the all so important earth ground at each building. But again, that and the resulting voltages are completely irrelevant to what the OP asked.

I understood your concern. That failure would result in low or no voltage. Meanwhile, the other neutral failure is, well, that was also explained: Of course that is completely irrelevant to the OP's question.

Destructive surges typically occur maybe once every seven years. But when an anomaly causes damage, then advertising has so many automatically blaming a surge. Too many even describe a blackout as a surge. Transients occur every day. Most are only noise. Transients that are made...

A term 'surge' or 'power surge' is quite specific. From the IEEE, an overstress condition that has a duration of less than a few milliseconds. A swell is an overvoltage that can last a few cycles. You have described an overvoltage. All specifically defined by the IEEE. But the OP was...

Obviously, other destructive transients (electric utility switching, squirrel shorting a transformer, etc) also create the same typically destructive transients - incoming on AC mains and outgoing to earth. These are a most common and destructive anomaly. Does not matter if the 'victim' is...

Does not matter if powered on or off. A surge current is electrically different (superposition) from AC power current. A surge current may even cross a millimeters gap inside a power switch. Or simply use the other AC wire to connect to earth, destructively, via an appliance. AC mains...

Surge protector is irrelevant. Also does not work as he has posted. RCD essentially counts the number of electrons going out on a hot wire and coming back on the neutral. If a miscount is too large, an RCD trips. So, why would current be going into the computer but not back via the...

Available are far more solutions that you want to read. For example, those two rings could be powered from different phases. Some manufacturers make a device (mounted in the power panel) so that radio signals (and not AC electric) passes from one phase to another. Wireless - if your...

The communication must involve two wires - not just a ring's safety ground. Numerous devices may 'eat' that ethernet signal. Apparently nothing on the local ring. Probably devices on other rings. One unit notorious from eating these signals are power strip protectors. Many eliminate the...
