re: Surge Protector/ Power Strip for Home office recommendations?

Best protection for any wiring - 1920 or 2020 - is that same 'whole house' solution. Wiring does not make damage easier. Generally wiring, not maintained, causes threats to humans - not to hardware.

Once a surge is anywhere inside, then it is incoming to every appliance (with or without a protector). It will find destructive connections to earth via one or some appliance. Often a destroyed appliance is protecting other appliances. Since that (and not other appliances) makes a best connection to earth.

What does not make an effective connection to earth? A plug-in protector (with or without a safety grounded receptacle).

Protection is always about this. Where do hundreds of thousands of joules harmlessly dissipate? Internal household wiring is always irrelevant. Since that surge must connect low impedance (ie less than 10 feet) to earth ground BEFORE entering any structure.

That is how it was always done in any facility that cannot have damage even over 100 years ago. That is also a many times less expensive solution.
