Installation of SWA cable

[ElecEngineer]

Can any one help..?

Having not installed any SWA before I’m about to undertake a job to install 6mm 2core cable to agarage. The cable would need to be buried for approx. 20m in the ground – whichI’m allowing to go 500mm deep. However it is when the cable first enters theground and when it comes out I’m concerned - remaining areas will be fixedevery 300mm onto concrete gravel boards etc – what mechanical protection would Ineed as it vertically enters and leaves the ground? To protect from strimmeretc.


Also I’m allowing for a IP65 rated garage consumer board withstandard sockets and switches - but are there any limiting factors ininstalling by windows and doors?

Why is your name elecengineer, if you don't have a clue what you are doing?

 

[Knobhead]

How long did it take you to qualify ElecEngineer?

Don't rise to it lads I bet its good old JRC with a new ID.

Double gasp

 

[trev]

Gasp! A two core swa?!
What are you going to use for an earth facility?

Double gasp

Mike your tongue must be stinging :willy_nilly:

That'll be what the metal coat hanger brayed into the ground is for.

Don't worry about it Trev - this guy is an ELECTRICAL ENGINEER - he knows what he's doing

Anyone got a spare gasp I can borrow

It seems there's not many left and I could use one in another thread

I blame the overuse of double gasps lately

Why, we're not allowed to hunt in packs there!

With immediate effect all gasps are rationed to ONE gasp per thread until further notice.

Having not installed any SWA before I’m about to undertake a job to install 6mm 2core cable to agarage. Good plan...who needs earthing anyway?The cable would need to be buried for approx. 20m in the ground – whichI’m allowing to go 500mm deep. However it is when the cable first enters theground and when it comes out I’m concerned - remaining areas will be fixedevery 300mm onto concrete gravel boards etc – what mechanical protection would Ineed as it vertically enters and leaves the ground? To protect from strimmeretc.No mechanical protection required,but if you can find room on the DB apply a 'NO STRIMMERS' sticker. If not you will have to install another DB to accomodate it.


Also I’m allowing for a IP65 rated garage consumer board withstandard sockets and switches - but are there any limiting factors ininstalling by windows and doors? Same rules as sinks I believe....minimum 150 mm distance....(or is that gas pipes?)

Hope this doesnt help.

Can I now place a copyright on the phrase "Sharp intake of breath"

Only if I can have 30% of the royalties.

 

[trev]

I'll go as far as 15%

Done ... and I think I just have been,

 

[Knobhead]

We seem to have lost our engineer friend for some reason.

 

[ipf]

Now thats how to negotiate a contract......quick and to the point. Who needs solicitors and accountants when we have geordie engineers.

Sunk like a stone & lost without trace.

Y'see .. these present day Electrical Engineers just don't have the staying power.

 

[trev]

these present day Electrical Engineers just don't have the staying power.

Or the education and ability to install armoured cables

...Once upon a time,there were twin brothers,one was very keen on earthing and went to work abroad....the other one.....

OK chaps, since I'm a bit late to the ridicule party, and it's not really my thing anyway, here's a sensible answer to the issue of cable protection on exterior walls (if required):

19mm x 19mm Cable Guard - 2Mtr Length - Black

 

[ElecEngineer]

A TT system from at the garage end! - which is considerably more reliable than trusting 30m of CPC buried in the ground

Hmmm, Really?? Well if you say so, it must be right!!!!! I'll now have to re-evaluate the 100's of thousands of metres of cables i've had buried under the ground over the last 40+ odd years!! I guess the vast majority of all the other Electricians and Engineers will have to do the same now too!!

well with all you experience; is TT earthing arrangement on the garage end not sufficient - The steel armour will obviously be earthed at the CU (with RCD)

 

[Plonker 3]

Why don't you trust a CPC buried yet will quite happily bury 2 live conductors?

You're digging yourself an even bigger hole now, ....why would you have an RCD at the supply end, when you're installing SWA cable?? Are you not installing a garage RCD CU at the load end of this cable??

I wouldn't install a TT system at a garage, unless their was no other way other than to TT it.

 

[ElecEngineer]

the way I see it - you could do it either way - I plan to use a TT earthing arrangement at the Garage end - Are you saying this in some way is not effective?!

Not really - I obviously plan to use a RCD unit in garage - I know this may cause both house and garage to trip but I want RCD on the Garage board and we all know the SWA must hav RCD protection...right!

I'm gonna say at this point this is a definite wind up. If not, put the tools down and get an electrician in.
