Discuss faults, cables spur from mcb. in the Periodic Inspection Reporting & Certification area at ElectriciansForums.net

you can have as many sockets in a radial circuit as you want

but any more than one s/o on the radial circuit you create then you need to protect the circuit by using fused spurs.

as for the disconnected phase being 'live' at 170v, this is very unusual. i'd unplug everything from the circuit (incase for some reason paranormal reason there is any abnormal capacitance, voltage sources like batteries there) i'd also disconnect and do some extensive IR tests to see if you've got any sort of leakage. i can say i've not come across anything like this before, except in emergency power/lighting supplies

let us know how you get on with this, i am intrigued
 
hi thanks for the comments, it is on a lighting circuit, but the batt in em lighting should have nothing to do with it. this has never proved a prob before or on any other similar circuits in the building.

im looking into it and will let you all know :)
