Seems on topic to me. Safety, EMI/EMC and damage protection are key aspects of owning a lab.
I have all my lab gear running off a Topaz 2.5 kVA ferroresonant isolation transformer. And everything from the transformer to the back of the instrument is inside EMT or MX. I don't have a whole house system, but do have a natural gas genset. So a whole house surge protector is probably a good next step.
BTW *EVERY* bench should be running through an isolation transformer if you use a Variac. At least if you like living.
Have Fun!

Looking for DIY construction project References? or? .pdf's ? in QEX or QST or other , for Surge Protectors
?capable of protecting a Whole Amateur Radio Shack or/&? Electronics Lab at the Breaker Panel or Sub-Panel level.
? The articles would typically list the component, have a schematic,? and the "best-practice"?? PCB? layouts already worked out.
Of course, a number of Commercial products are available, such as the Siemens FS-140, which has good specs.
These are listed as "Whole House Surge Protectors" (WHSP's).
?? An example? article of listing of such can be found here:
However, the cost for the Siemens FS-140 or other modules is steep,? in the $300 to $400 range, while the actual components costs are? in the $20 range.
-? not a bad cost bad for a single home,
-- but with multiple buildings on a farm, and separate antenna shacks , the cost for 8 of these adds up.
So,? looking to build some myself.
It is not that difficult a thing to do, and I have added MOV's to specific individual equipment myself across the L1 L2 & ground lines,
? (both internally & externally) to protect them, and that has worked out fine.
Thus the request for some DIY ? .pdf's?? articles?? or? Web Reference? from say QEX or QST? or other, for my own self-edification, would be appreciated.
thank you,
