Heres one for you guys, not sure if you've ever given it a thought but an operator at my workplace today mentioned that he keeps having power dips / losses to every other house in his street, so obv i thought 'ok there is probably some issue with one of phases supplying your area'. anyway so he confirms this by telling me his nextdoor neighbor still has power when this occurs, andso, he went and did the dreaded and now has a.. wait for it... socket outlet in his house that is supplied from nextdoors supply (with their permission ofcourse...). now apart from the obvious things wrong with doing such a thing, surely there is the potential of 415v should a fault possibly occur between the two houses.. scary stuff... :eek:mg_smile:

well yes...if both houses dont share the same phase...
interestingly enough...have you seen the offender (socket)...and where its getting its juice from?

Lots of house have a 3 phase supply and the possibility of this kind of fault, some lighting circuits are designed to have different phases at the same switch (2way landing scenario) comes down to making sure they're seperated

Its 400v now when discussing but apart from that minor point as long as 2 power points can't be reached similtaneously then no issue if they can then a clear warning label needs to be affixed regarding the 400v that exists between the 2 points.

More so the socket pinched from next door has other issues regarding its presence... consider a fire and the fire services isolate the supply at the consumer unit for safety not knowing that it dosn't isolate all power, consider a fault with this socket where it start smoking arcing etc maybe due to damp.... how do you safely isolate it if neighbour isn't in??? the list goes on and are you joking about the neighbour knowing its pinched supply or is there a real agreement over this situe?

This topic is often asked from domestic sparkies but 3ph IS common in commercial and industrial to be found as already posted in switches etc and been in close proximity in outlets like commercial kitchens etc and all the regs specify on this is appropriate warning labels are present if voltages exceeding 230v are found where not expected or between adjacent outlets that can be both reached similtaneously.
