This came to my attention recently. After 2 small incidents on board company vessels. One in a office the other in crew accommodation.
The use of surge protection is now commonplace for all kinds of electronic devices particularly personal devices. The CE brought it to my attention after discovering a failed non marine surge protector on board. We found several others on board brought by crew who were unaware of the issue. I was not aware either.
Most store bought surge protectors are not designed for use with the 3 phase electrically supply for on board generators and may fail causing a fire. Explaining this 3 phase thing is beyond my deck comprehension but I take the chiefs word.
Just thought it was worth mentioning.
Also without any information, purely idle speculation,
Could this be just as plausible a possibility as lithium batteries as an unknown cause if a recent small passenger vessel fire
The problem has to do with the type of transformers used to step down to 120vac, not that the ship generates 3 phase power. On many (but not all) ships both sides of the 120vac receptacle are hot to ground. With no neutral side a non marine surge protector can be a fire hazard.
