flor, just a few basic rules of thumb to disprove your theory of total demolition.

Ever looked above a ceiling, or inside a distribution board, or at a socket outlet supplying numerous extensions, or at site temporary supplies (have you checked the earth.....does it exist

Ever heard of a visual inspection (the title gives the game away), well its normally carried out where wiring / cabling is exposed and generally followed by cold wire checks to determine conductor integrity....especialy good for the hard to view places like embedded installations and such like, and particularly useful for avoiding total demolition to check wiring

Think you should keep quiet flor, what is left of your tattered reputation is fast disapearing down the toilet!!!!
