No protector does protection. Effective protectors (ie whole house) are connecting devices to what does protection. A protector is only as effective as its earth ground. Protection is defined by what harmlessly absorbs hundreds of thousands of joules - single point earth ground.
Ineffective and obscenely profitable devices such as a Furman are only magic boxes hyped subjectively as surge protectors. Subjective means a recommendation has no spec numbers. No numbers is how ineffective products get recommended. Where does it claim to absorb hundreds of thousands of joules?
Type 1 does not define protection . Type 1 is a human safety parameter. A world’s best Type 3 protector in a Type 1 location means a potential fire.
Key to protection is the quality of and connection to earth ground. Since that is where hundreds of thousands of joules harmlessly dissipate. Protection is always defined by spec number.
Key to protection is a low impedance (ie less than 10 foot) connection to single point earth ground. All four words have electrical significance. That hardwire connection must have no sharp bends, no splices, separated from other non-grounding wires, and not inside metallic conduit.
Above is protection from ’each’ surge. Lightning is typically 20,000 amps. So a minimal ’whole house’ protector is 50,000 amps. ’Life expectancy’ means an effective protection remains effective for decades.
Above discusses effective protection from ’each’ surge and protector ’life expectancy’ for decades - with numbers. All appliances already contain robust surge protection. Your concern is a rare transient that may overwhelm that protection - maybe once every seven years. That potentially destructive transient is the primary purpose of a properly earthed ’whole house’ protector.
A ’whole house’ protector is protection from all types of surges - including direct lightning strikes. Then hundreds of thousands of joules dissipate harmlessly outside. Some previously discussed protectors have no earth ground - do not claim to protect from potentially destructive surges. Those plug-in devices (ie Furman) must be protected by a properly earthed ’whole house’ solution. A protector is only as effective as its earth ground. Then even direct lightning strikes cause no damage.
