How long does your Surge Protector LAST???

Clearly you don't understand that an EMS / surge protector is designed to be sacrificial and therefore designed to "fail" under some circumstances, thereby preventing damage to your trailer's electrical system.

Some surge protectors do that. Not to do protection. When grossly undersized, a surge too tiny to overwhelm protection inside appliances also destroys that near zero protector. Then many naive consumers recommend that protector.

Many completely different and unrelated devices are called surge protectors. That power strip using MOVs is completely different from what a Progressive might do. For example, low voltage (according to hearsay) is called a surge. A Progressive will disconnect on low voltage. That power strip inside a house ignores everything until 120 VAC well exceeds 330 volts. A number clearly on every box. That is the point. Many know by ignoring numbers. Then assume 'sacrifice' is protection. It is not.

Near zero power strips do sacrifice themselves ... after that surge current is both incoming and outgoing (into appliances) simultaneously. A thermal fuse (sacrifices itself) disconnects protector parts as fast as possible to avert a fire; leaving that current still connected to and flowing into attached appliances. Where is this protection? A surge too tiny to overwhelm protection inside appliances also destroys a 'sacrificial' protector.

Effective protectors do not fail. Grossly undersized protectors (with obscene profit margins) fail.

Long before assuming all anomalies are 'surges', instead define and discuss each anomaly separately.
