Open neutrals are no joke, here’s a good analysis of a similar situation that caused a house fire: https://www.electrical-forensics.com/Open-Neutral/Open-Neutra

Here in Australia the coax connection from the street typically goes through a galvanic isolator to avoid this situation, rather than being bonded to the earth.
- C1sc0cat 6y agoWow what a mess
- _trampeltier 6y agoOpen neutrals are no joke but each case does give a good story every time again. I know a guy who cut a 70mm2 neutral in a factory. They had a lot of single phase drive inverters. I think somethink like 25 inverters had to be replaced (and a lot of other stuff too).
- robocat 6y agoWhat do you mean by “galvanic isolator”? Link to coax example device? I’ve never heard the term before and a quick google is showing something irrelevant. NZer, so the language barrier exists!
- jhiesey 6y agoProbably an isolation transformer. A search for “cable tv isolation transformer” gives lots of results.
- 8bitsrule 6y agoHadn't heard the term before. Looks like its two diodes in parallel, pointing opposite directions, in a very-expensive box. Blocks low-voltage DC flow while allowing higher-voltage AC currents to pass. Looks like maritime usage is common. http://www.yandina.com/galvanicIsolator.htm http://www.yandina.com/galvanicIsolator.htm
