I already have a surge arrestor for my distribution box. Will that also help against ethernet surge issues?

Problem is the grounding of the ethernet surge protector is not that easy and I do worry wat could happen if the grounding socket gets loose and lightning occurs. There is alot of airflow in that room after all.

I cant seem to find an ethernet surge protector in a powerstrip or plug for 220volts. I would prefer that over a ethernet surge that has to connect to a ground connection


Hmm I also read that ethernet surge protectors tend to mess up bandwith network packets. That isnt good as I need it smooth. Is there such a thing as a netwotk switch with stronger built in ethernet surge protection than usual?

You are completely missing the point.

That safety ground is ineffective - as explained previously.

Protection means a surge current is not anywhere inside.  Once inside, then nothing (as in nothing) can avert a hunt for earth destructively via appliances.  Effective protectors always connect to earth BEFORE a surge can enter a building.  True today as it was over 100 years ago.

No protector does protection - not one.
 Stop assuming a protector is protection.

You are asking for a magic box solution.


Protection is always this:
Quote
Protection is always - as in always - about where hundreds of thousands of joules dissipate. Protection means a surge current is nowhere inside a building.  A protector is only as effective as its earth ground.

If any wire enters without making that connection to single point earth ground, then all protection is compromised.  Does not matter if a protector is in a distribution box.  How long is a connection from each wire in each cable (ie satellite dish, telephone, TV cable, invisible dog fence) to that single point earth ground.  That connection must be low impedance.  And that only earth ground must be a best earth ground.

Again, protection is always about where hundreds of thousands of joules harmlessly dissipate.   That is not a protector.  That is THE most CRITICAL device in your protection 'system'.  Most of your attention should focus on what does protection and the connection to that protection.  Then no surge is anywhere inside to overwhelm robust protection in every ethernet port.

Ethernet will withstand up to 2000 volt transients without damage.  Therefore all network switches have most robust protection.

But again, protection means a surge is not anywhere inside.  A protector is only as effective as its earth ground - including the impedance of that connection to earth.

A miner shutting down is irrelevant.  A UPS and a surge protector are two completely different and unrelated devices for completely different anomalies.
