Dangerous outdoor/garage wiring.

[Alex1M6]

Hello I am new here.

This is regarding my parents house electrical wiring that leads out to the garage.

Here is a small amount of background information, I am 17 years old and over the last year or so I have started taking interest in electronics in general and have learned quite a bit about many different electrical related things and had some experience.

Recently I have been reading up on domestic 230vac mains electrical systems when I installed and added an additional mains outlet in my room (which I installed fine and followed all of the different codes/guidelines regarding this).

How ever I noticed something interesting about the wiring that connects the garage which is a separate building about 15ft away from the house to the 230v mains, it seems that who ever connected it up basically ran what looks like a regular 2.5mm twin and earth (although I can not be sure there is an earth conductor) from the RCD box in the kitchen and ran it along the kitchen wall then through the wall to the outside where it runs along half of the length of the house and then is suspended over a 15ft gap where it connects to the garage. What is more is that the cable is exposed to the elements with no PVC pipe or anything to protect it, just the usual grey rubber outer protection.

I can see that the grey rubber protection is starting to show its age and wear off.

Does this sound safe? (I don't think it does), I have tried to explain this to my parents but they seem to think that becuase it has been like that for a number of years and works of they can just leave it.

Some things that are plugged in/used in garage are an old freezer,lighting (which is on the same circuit to the outlets, unlike the house lighting), and various other power tools.


The house is quite old and was built in the 20's/30's so I am not sure if this type of workmanship was acceptable back then.

I can provide photographs of the wiring if anyone wanted some.

Any thoughts/advice would be a appreciated.

Thanks.

Its not up to 17th edition regulations and it would be 'advisable' to have it re-done in SWA.

Yes provide images please.

Best put some pictures up and we can see what is happening.

“If it ain't broke, don't fix it” attitude, LOL

Sounds very unsafe! Time to call in a qualified electrician.

Thanks for the reply's, here are some images.

I think the gap is bigger than 15ft, but as you can see from the first two images the cable is just ran across the gap.

the last two images are of the part where it connects to the house and the last one is it connecting to the garage and you can see what condition it is in.




I am sure that a cowboy builder installed it like this.
Thanks.

Ohhh that looks like a nice piece of lead twin cable there and chances are no CPC so I think it is time it is changed as it is also going a lovely green colour.

How would you want to replace it?

It would be a case of persuading my "If it works, leave it" attitude parents that it needs replacing and to get someone in to redo it.

I can't say for certain what the cable type is, but it looks like Malcolm may be right with LI but at least it looks like it's on a properly installed catenary wire.

In fact is it the PVC coating on the catenary that you can see 'coming away' ?

As your 17 there is a chance that your parents are younger than me, and yes and I still do have the attitude that if it is working leave it alone. All I can say if it is lead then IMO I would not even try to investigate it, as you could be making a bad situation worse.

All you can do is advise them that you have come on here and spoke to us guys that recommend that they get someone in to look at it. It will cost you nothing as you can ask for quotes about changing it which are free, and get 3 independent electricians in, I'm pretty sure that all 3 will say the same, it's had a good life but let's change it.

Whoops, I mean cable not lead (People around here often refer to cables as "leeds" as in extension lead).

Sorry for the confusion!

By "catenary wire" are your referring to the wire that contains the conductor or the support wire that it is attached to?

Yes, the catenary is the support cable, sometimes these supplies are literally 'washing lined' between buildings!

 

[Alex1M6]

Thanks for the advice, I will tell them about this thread and tell them you guys recommended someone look at it.

Besides I have found something that should pursued them even more on the front of the fusebox/rcd panel.



Hard to see but it reads:

"Date of last inspection: April 80"
"Recommended date of next inspection: April 94".

Which I think should be a good incentive to get it all checked out in general.

I expect that RCD (or RCCB in fact) works wonderfully if it is functioning, not like these new fangled 61008 things.

Everytime I go to a house that has a really old RCCB (up front or in the board), and I test it just to be happy, it always amazes me how fast they trip in relation to brand new ones I fit.

Sounds and looks like it was rewired in 1980 then. Well overdue for an inspection, especially as you seem to think Bodgit Bob has had a go at sometime.
