Greetings,And in that moment before the circuit breaker on your generator trips, your 120/240 volts has been stepped up to 7200 through the "pole pig" transformer in your neighborhood, and has KILLED the lineman working to fix that 7200 feeder circuit.It only takes a MOMENT to stop someone's heart through electocution. It takes several milliseconds to pop a breaker.
And it would have only taken that lineman a few seconds to attach a grounding bond to the supposedly dead feeder and transformer before grabbing it bare-handed while speculating as to why it sounds like there's an engine running at constant RPM coming from the house connected to the service drop.
Serious accidents are often caused not by a single failure but several. -- Jay Hennigan - jay () west net Network Engineering - CCIE #7880 503 897-8550 - WB6RDV
