can it detect live wires behind plaster board?

It all depends on how far the wires are located behind the plasterboard - however there is a 50/50 chance of this type of detector being able to detect live wires behind plasterboard - try searching for a Draper 13818 Combined Metal Voltage and Stud Detector. Regards, Testermans
