He's a cowboy trying to rip you off. A new house should have an inspection
certificate, so ask for a copy, then contact the person that arranged your
survey and complain. You can't have both live and neutral on a neutral
block or your main fuse would blow. What he has measured is the voltage
between neutral and earth. If you have fluorescent lights this sometimes
happens. It can happen if you have a faulty TV or video.

Sigh.... Just beware that 'ron' has a poor understanding of electricity
judged from previous ramblings in usenet, and is mostly trolling...
