I think what sterose is suggesting is that its safe for a temporary DIY job, but thats it.....personally I wouldn't do it in a clients house and I wouldn't recommend it.....but in my own house I would consider it....as a spark you know which rules you can bend...and so on for any trade....as I always say there are standards, Professional / DIY / Cowboy and you pick one depending on your circumstances, and they can all be safe (ish)
