The terminals are not large enough for a 16mm cable.

Re: Tell us about your faults !

what are you trying to get 16mm into? maybe that the accessory is not rated to the current that 16mm will carry.

Re: Tell us about your faults !

Hi everyone, this is also my first post but could'nt resist replying...got an enquiry from old customer who had just bought a barn conversion but none of the lights or sockets worked....off I went armed with tester, neons etc .....got to house plugged in socket tester..nothing....dropped switch cover..no live.....took cover off fuseboard and found all cables unconnected and just pushed back into box...then saw there was no incoming supply...!!!! must be what they mean with 'buyer beware'...

Hello again....just remembered another one...several years ago I visited some friends who had just bought an old farmhouse..there was an attached barn partially converted which was now being worked on by the new owners...as I chatted to my friends the carpenter mentioned that when he had moved a drum of cable he received a shock....I was a bit sceptical but went to have a look anyway...I found two drums of cable, lighting and power, with cable running off into the stud walls...not only were both drums 'live' but so were some of the cable ends sticking out of the plasterboard...someone had second fixed the fuseboard...!!! with no rcd on the system either this could have been very nasty...

Both the upstairs and downstairs rings had been wired into 2 different 32A MCB's.

I've seen that before in a commercial environment, except that the different ends of the ring had been wired into the same phase on two different DBs! In different parts of the building! Came as quite a shock when the electrician turned off the main breaker on one of the boards and discovered that one of the phases was still live with no apparent source...

Not so much a fault, but a friend of mine asked me to go round and give him some advice. Wasn't expecting to find this,there was once a wall there but he has knocked it down and he wants to move the meter and just asked if it was OK to put new tails in :shocked3:. As he thought all he has to do is bury any excess cable from the DNO under the floor.

I should of may be been a little more professional but I just had to laugh as it was all I could think to do. I think he got the idea though, I have no idea what he is going to do and don't dare to ask neither.

I've probably mentioned my "classic example" of something similar on here before. In case you haven't heard it; working on a village shop which had two 6/8 way Wylex c/units. One of the circuits (ways) in unit A was fed into one of the circuits (ways) of unit B. My mind still boggles at the dangerous situations that that scenario would create. Switching off unit A would mean unit B would still supply it thro' a fuse-way onto the bus-bar........and vice versa.
Also recently, while upgrading a mains consumer unit (in a builder/DIY's house) I discovered, the hard way, that two of the lighting circuits (fed from two separate ways) had been "turned" into a ring main. Never assume anything or take anything for granted - you're a long time dead!

Spot the fault if you can on this bathroom vanity mirror light...

A hint is that the customer says the lamp blows instantly when the switch is pressed..."but it has been working fine"
