What are the implications of switching a current carrying conductor main feeder that has been shorted with one of the neutrals? This is a 480/277v system.

No matter the implications, if you know this to be a fact... or even if it is just possible, verify, fix if so, verify fixed or good before anything else.

Welcome! :)

Are you asking about the likely results of closing a switch or circuit breaker onto an existing fault? Arcing or bolted fault?

I think he wants to know if there will be problems if he takes a shorted hot feeder and makes it the neutral and uses the neutral as a hot feeder.
In other words swaps them on both ends.
 
qcroanoke is correct. The contractor I am working for is wanting to do this and I told them they in turn would energize the shorted point and depending on the available current on the neutral cause an arch flash

If the hot is shorted to ground and you swap neutral and hot on a line-to-neutral 2-wire circuit, you most likely will not get an arc flash... but the circuit will have a parallel neutral pathway on the equipment grounding system, creating shock potential.

I agree, but I have seen it done many times. :roll:
