So many say, "I have this. Therefore it must be best." Why does hearsay without even one spec number or hard fact become an honest recommendation?
Surges that do damage can be hundreds of thousands of joules. How many joules does that Panamax claim to absorb? About 550 and not more than 1100. What happens when a destructive surge happens? Either it must block that current or absorb that energy. Clearly 1100 joules cannot absorb a transient that is hundreds of thousands of joules. Clearly its 2 cm protector part cannot stop what three miles of sky cannot. So what does it do? Numbers say ineffective.
First, it claims to protect from another type of transient that typically does not do damage. A transient made irrelevant by superior protection typically found in all appliances. Second, it must disconnect it protectors parts as fast as possible during a significant transient. Otherwise those protector parts can cause a house fire. Leaving a surge still connected to an adjacent appliance.
Since appliances already contain superior protection, then a surge too tiny to damage appliances can cause an undersized protector to fail. That failure get the naive to recommend it.
Why do so many recommend without numbers? Notice how a recommendation is 180 degrees reversed as soon as technical numbers are included.
Confusion abounds. That undersized (ineffective) protector and a superior solution share a same name - surge protector. Facilities that cannot have damage use something completely different. You could have same for about $1 per protected appliance. How much was that Panamax? $80 per appliance? It does not even claim to protect from the other and typically destructive surge. The effective solution means even direct ligthning strikes without damage even to a protector.
Facilities that cannot have damage do not waste money on Panamax. Since a Panamax must be protected by a properly earthed 'whole house' protector. Numbers make that obvious. An IEEE Standard defines properly earthed protection as 99.5% to 99.9%. Yes, that Panamax can do more if used in conjuction with a properly earthed 'whole house' solution. It may add another 0.2% protection. Yes the Panamax can increase protection. Then include numbers.
Effective protection means one says where hundreds of thousands of joules harmlessly dissipate. Any recommendation that ignores numbers is best considered bogus, hearsay, or junk science. Bogus recommendations are often due advertising claims - without numbers. Reality is completely different when specifications are included. But more important is why the 'whole house' protector does protection and the Panamax does not even claim it. Single point earth ground is only found with the 'whole house' solution.
Panamax will not discuss earthing for good reason. A $3 power strip with ten cent protector parts selling for $80 ... why would they risk that obscene profit margin? Fewer who actually know these numbers post a completely different recommendation. Where do hundreds of thousands of joules harmlessly dissipate? No answer says why many had a protector adjacent to electronics and still had damage.
The rule is simple. A protector is only as effective as its earth ground - that a Panamax does not have. Earthing is why facilities that cannot have damage always use the other and well proven 'whole house' solution.
