There are some interesting posts in the archive.. I remember this one of Zs for example 

Nothing so odd to report for myself, but  a few funnies over the years.

I have been involved in needing to replace the shear pin on a generator set where in effect it revved up, then the contactor closed and put the genset in parallel with  an incorrectly phased supply -very much a red face moment. Well at least one of us ought to have been concentrating harder.

I have been stopped by a breathless range officer from hammering in an earth rod because of a risk of finding unexploded ordnance buried under where we were going to set up.  ("you are now going to put the lump hammer back in the truck, very carefully, and then reverse it out, very slowly and gently, and I am going to stand over there and watch")

I have been removing an elderly bladed fuse, in hindsight, perhaps with a little too much gorrilla muscle, and the board came of the wall on its fibre rawl plugs too.

I have removed the downstairs lighting fuse for a house, then removed the hallway light fitting and ceiling rose, and fitted a new fitting, only for the light to come on in my hand. Not on that circuit after all then...

On a similar note, I have climbed into the loft with the fuse of the circuit I was working on safe in in my back pocket, and then cut through what I thought was the right cable, and been greeted by a load bang and a flash, and a very nasty shock limited by the RCD.

I have also carefully laid in and plastered over a cable in a wall, and then a couple of weeks later, drilled into it.
