uski Posted March 19, 2007 Share Posted March 19, 2007 Hi, A relative asked me to find some spare remotes for his electric gate; before I answered I wanted to know the manufacturer and PCB model of his controller, so I opened it and found this: The relay, with live 220v in it, fallen into my hands when I removed the cover. And they used telephone wire to supply the 220v to the lighting of the entrance. And it's not a DIY job Is it only me or you also encounter this kind of horrible installs from time to time ?.. uski Link to comment Share on other sites More sharing options...
luggsey Posted March 19, 2007 Share Posted March 19, 2007 It's neat compared to the one I'm fixing at the moment. Seen open contact type relay bases used on 240 inside a sliding cupboard in a shopping centre, seen a keyswitch in same shopping centre with bare contacts at 240v, no insulation whatever, almost got a shock off that one! ----------------------------------------------------------------------------------------------------------------------------------- Life is like a box of chocolates, some bugger always gets the nice ones!

uski Posted March 19, 2007 Author Share Posted March 19, 2007 yes these types of jobs come to light form time to time. are you sure telephone vcable was used for 220v could it have gone somewhere else mayybe 12vdc cjt Yes it's really the 220v that was in the telephone cable And I remember I also found a door contact with no insulation in a shop, detecting the opening of the door and triggering a relay to ring a bell when someone was entering the shop. I inadvertently touched the top of the contact and got a small electric shock... and this was done by a "professionnal" electrician :/ Link to comment Share on other sites More sharing options...
STEWENG Posted March 19, 2007 Share Posted March 19, 2007 A few years ago I went to fit an extra PIR in a house that was having an extension built. The panel was a 10 year old Logic 4, in perfect working order, 'never had any trouble with it!' The 230V supply was cabled using the same 4c alarm cable as the PIRs, and to top it all..........only two cores were being used!! Black and red of course!.........But no earth? Fair enough though, they did use a fuse spur, even if it was the boilers. DIY job, son had just left uni apparently, studied pyrotechnics by the look of it!

breff Posted March 19, 2007 Share Posted March 19, 2007 i know why he did it to save on the fireworks on nov 5th but seriously thats really bad i hope you put it right of course. cjt Yeah, he used the yellow core for an earth.

breff Posted March 19, 2007 Share Posted March 19, 2007 No, he put green lines on it with a felt tip pen. Only joking of course, steweng. The opinions I express are mine and are usually correct! (Except when I'm wrong)(which I'm not) Link to comment Share on other sites More sharing options...
STEWENG Posted March 19, 2007 Share Posted March 19, 2007 i know why he did it to save on the fireworks on nov 5th but seriously thats really bad i hope you put it right of course. cjt Of course! They were horrified when I pointed it out and wanted a complete new system. I have seen an old but live socket under a bath in a house that was being converted into flats, I used it to charge my drill because the house still had work going on and it was the most convenient point. The electrician had finished his work and was not coming back. Some people say it is illegal others say not, some say as long as it is bonded locally to earth it is ok? The only way I think that could be legal is if the bath panel was fitted in such a way that there was no access to it and RCD protection? Any opinions out there, obviously I know it is not recommended but does it go completely against the wiring regs! Link to comment Share on other sites More sharing options...

Truss and France Posted June 16, 2007 Share Posted June 16, 2007 This is a pic of what I found above the false ceiling while I was commissioning a system installed by a subby! The question I have to ask is why? Lack of experience, lazy or was it the trainee. The easy way to sort this out is to take a photo (like you already done), put it right take another photo for proof and then deduct your time in money from the subbies payment. Its the only way to make subbies learn that if they want work then they need to do it properly. In this case I can see no excuses for doing that way. I am subby and it annoys me when I see things like this because this guy calls himself a subby when really he is a 'chancer', lets see what we get away with attitude Its sad.

tinnitus Posted June 20, 2007 Share Posted June 20, 2007 im working in a little shop installing security at the mo .old trunking running everywhere, not nice. its also quite untidy. the previous owner had left a drum of mains cable in a corner, i thought nothing of it and it wasn't in my way so i didn't touch it. the new owner and my customer was moving sockets and was trying to trace cables from the fuse board, guess where the cable wired into the 30 amp fuse went? that's right, the cooker, only joking it was the drum of cable in the corner, live and 30 amps!
