Faulty electric circuits caused IMPZ fire

Electrical Fires
It is time to employ modern cable systems and get rid of single core cables running in galvanized steel conduit. Electrical cables surface mounted should employ NYM type, multi core insulated cables within a single insulated sheath run on trays or in PVC or ABS conduit. Much safer and less chance of damaging cable insulation during installation. Screw type plastic cable connectors are very often used above ceilings and left exposed,and all too often, the connectors are overloaded resulting in loose cable connections. WAGO self locking push type clips are much safer and impossible to overload. Sub surface cabling is best achieved using multi core ribbon type cables such as IMPU. This allows a faster, cleaner and safer installation of all in-wall cabling. It is a great contradiction to boast about all the mega projects, biggest, longest, tallest etc. when behind the glittering facades, ancient technology in electrical works still prevails. Less dangerous to life are the low standard plumbing installations. The visible fixtures are always top notch, but what you cannot see is the poor installation practices hiding below the surface. Some habits certainly die hard! It is absolutely imperative that construction companies employ first rate site supervisors. In my experience over the last decade and more, is that site supervisors and project managers are sloppy,under qualified and overpaid. The labor forces employed in this country are of limited qualification and require good supervision to get a job done well. Quality has to start at the top, and be followed all the way down to the screwdriver!
