Fear of voltage drop!

[MDJ]

the fault current would be proportional to the voltage, so if the volts were down by 10%, then so would the fault current be 10% less. 900A as opposed to 1000A. don't think OCPD would be too bothered by that.

Yep ohms law, your right tel

Agreed - but I was talking about volt drop generally and perhaps more excessive than 10% - Just making the point that it may not only be the operation of equipment that you have to consider in these situations, especially if you are intending to 'non-comply'.
