This can create an imbalance of voltage between various power conductors supplying power throughout the ship, which can cause overheating and eventually fires.

The outlets are three prongs, but the ship uses a 'floating' ground, where the wiring ground is connected but not really 'grounded' to the earth.īecause typical surge protectors only disrupt one of the live currents, in a ship scenario, the second current continues to run. The current is shaped in different phases (unphased), so the voltage potential is always 120v.īoth prongs carry a live current, and unlike a land-based circuit where only the live prong would give you a shock, both prongs can shock you on a cruise ship. There is a view that thin profit margins were not the prime cause of Walmart's decision. The live wire carries +60 volts, and the other conducts -60 volts. The original Kindle Fire secured one-fifth of the US market. Instead of only one prong being live, cruise both the (live and neutral on land) wires. Why would they make a rule like that? Doesn't make sense to me.Ĭruise ships (and other large ships) use an UNGROUNDED system to work around this.
