If it is a surge protector, then it better have a UL 1449 listing. Since those can be a fire hazard. That fire hazard risk increases if a 'whole house' sollution does not exist. Protectors without UL1449 are a greatest fire hazard. Go the Belkin site to only read specification numbers.I have surge protectors (Belkin) and USB chargers (Anker) and neither have a number on them. They have the UL symbol, but no 1363 or 1449. They all have different numbers that start with and E. So do I trust my plugs?
You have zero reasons to believe that Belkin is doing any effective protection. Read its spec numbers. We did analysis where plug-in protectors even made damage easier; bypassed what is better protection already inside a PSU. Anything that plug-in protector might do is already done better inside appliances - including portable ones.
As stated previous, that Belkin "must be protected by something completely different called a 'whole house' protector (if properly earthed)".
"A device put on the house panel" is a 'whole house' solution. As true for all protectors, that 'device' is only as effective as its earth ground. Earth ground (not a protector) is the item in that 'solution' that requires most attention.
That Belkin has no earth ground and will not discuss it.
