Noticing more of this forum doing the same, albeit not necessarily 480's fault.This is a WORTHLESS thread! It is of ZERO value to anyone.
I remember other "STSC" threads that brought criticism similar to several posts in this thread, and wonder if those who don't like this kind of thread might just stop reading, leaving it for those of us or are interested?
If anyone says breaker throws sparks, I believe OSHA or NFPA 70E prohibits turning it back on in the faulted condition...I guess first thing I do is try to turn on the breaker. Presumably it must have "thrown sparks" or whatever..
Since when are you allowed to have two fuses power the same wire?If anyone says breaker throws sparks, I believe OSHA or NFPA 70E prohibits turning it back on in the faulted condition.
You should check if breaker is energized in the off position, and if so check for line-line potential between the other source.
If more than one fuse powers the same wire, find other fuse powering it, & cap off wire from highest Amp fuse.
When I cap off such a wire I also wrap white tape around it and label it "FAULTED"
I believe he is referring to situation where you might have power coming from another fuse/breaker whether unintentional or even say a line to line load where the other device is simply the other side of the supply for this circuit.
