SquareD says for their "best" service panel protector "electronic

And then numbers that sales promoters fear to provide. A 'whole house' protector does maybe 99.5% of the protection. Then a power strip protector can do an additional 0.2%. To be closer to 100% protection, spend another $2500 on plug-in protectors for an additional 0.2% protection. Why do you always make claims by forgetting to include the numbers? Subjective claims (lies) can manipulate the naive. Ignoring numbers to take statements out of context is a classic sales promoter stunt.

A power strip protector needs protection by earthing and a 'whole house' protector. A 'whole house' protector doing over 99% of the protection does not need a power strip to protect it - to even avert fire. Use power strips to add maybe 0.2% protection - to get closer to 100%.

Catastrophic power strip failure is a problem traceable to undersized protectors that do not disconnect from a surge fast enough. How do hundreds of joules in a power strip somehow block or absorb surges that are hundreds of thousands of joules? Why do sales promoters never have an answer for questions that include those damning numbers? For the last ten years, your only reply has been crickets. Honestly is not what they hired you to do.
