As you can see, it has outlets, USB ports but no surge protector. Absence of the text describing it having a surge protector does not guarantee it has no surge protector. It isn't likely, I suppose, but I sure wouldn't want to bet on it. Unless you tear it apart and examine the guts, you have no idea what going on in there.

Not likely they would spend to include a surge protector and not advertise it unless they are marketing to cruise passengers….like if it says cruise approved which is a marketing scam. A 3 pronged plug like in the is a necessity for effective surge protection but does not necessarily indicate surge protection. Link to comment Share on other sites More sharing options...

It can be done hot-neutral, even in a split phase system. 2) Total cost for surge suppression components in normal surge suppressor: approximately 5 cents.

Royal's new ship does have a regular plug in the bathroom. Link to comment Share on other sites More sharing options...

I know some people need a CPAP but what else are you bringing aboard the ship? 2 tablets, phone, cpap, watch, fan, air purifier, electric razor. 1 Link to comment Share on other sites More sharing options...

Power switches generally have similar same issues in a split phase supply as "surge suppressors" - the switch generally only turns off one phase (hot), leaving the neutral with 60VAC relative to "ground". It can also back feed from power strip neutral at 60VAC through a plugged in device to the power strip hot - causing partial voltages on anything else plugged into the power strip, which is a fire hazard. A switch that only breaks one leg in a split phase system should not be allowed - and they aren't going to check and see if it's a switch/breaker that breaks both legs or only one.

The big problem with TSA is that the rules are: 1) What the rule book says 2) Or anything any individual TSA agent says, even if it contradicts the rule book They specifically have a cut out that basically says "The TSA agent is right, even if they're wrong". Whether to let anything on, no matter what the rules say, is at each TSA agents discretion. Link to comment Share on other sites More sharing options...

This was one of the major points in the USCG Safety Notice about using surge protectors on ships, where they sort of conflated the problems of surge protectors with the problem of a US consumer power strip only breaking one leg of the circuit. This is why you will find the ships only use European 220v power strips, where the switch (circuit breaker) breaks both legs of the circuit. 1 Link to comment Share on other sites More sharing options...

Yeah... there are a lot of related issues there. 1) If it's a switch - does it break both legs, or only one? 2) If it's a circuit breaker - does it break both legs, or only one? 3) If it has voltage surge suppression - does it do phase-phase suppression, or only hot-ground? 4) If it has a fuse - are both legs fused or only one? 5) Can the Class X/Y capacitors in the input filter handle split phase supplies? ...and this ignores that almost any corded appliance with a fused plug - presents the exact same issues, and aren't necessarily banned.

Even those you can't necessarily trust - dual pole breakers and switches generally fail on a single pole first, so you could potentially still have the situation. There are good arguments for just not allowing any switches/breakers on many split phase supply. Link to comment Share on other sites More sharing options...
