Onboard ships, the most common electrical distribution is 110V delta (63V to ground), with two hot legs wired to every 120V receptacle and device. I've heard two reasons for this- one is safety; 63V to ground is a lot safer than 120+V when the sailor and the panel are both submerged in salt water. The other is ground fault tolerance; any one phase can fault out, and the power distribution system will continue to work. Pretty much every electric device ever made works fine with this.
I was just wondering if it blew any young engineers' minds that such a system existed?
