Right or Wrong - Termination of SWA - Opinions and Suggestions please guys!!!!!

[harrison2987]

Above is a picture of 2 16mm SWA cables terminated into a termination block. In my opinion this is the correct way to dress in the SWA and terminate it into the incoming side of the termination block, not putting it into the same termination as the outgoiong cables.

Is there a reg that says you have to terminate like this? Or is it just good practice to do so??

Below is how another spark has terminated the 2 SWA cables. He has gone straight into the top of the termination block, into the same terminations as the outgoing cables.



Just to be clear there are no fuses on this termination block, it is simply a through termination, i just want to know which way is corrct or better practice and if there are any regs to say which is the better way to terminate.

Thanks in advance for your opinions and help!!!!

Its a lash up, and the grey core should be strapped to earth.

2 different sparkies!!!! ... come on own up which one is yours?

Technically although nobody really does it - its the black core that should be earth and the grey neutral.

How come?

I wouldn't have that flaming great loop inside of the box. I'd have made it a not neater in there, in on one side of the box out on the other where possible.

I agree, but space is an issue in the box, i suppose it falls to poor cab design and lack of space. In some of the boxes there are 4 16mm SWA's coming in!!!! Just not enough space and the location of the terminal block is poor aswell!!!!

Do you think its pointless having that loop and you would go straight into the terminnals??

Some people have no class!
What's occurring with the chains, bottom left, plus the bare cores sticking out of them glands?

OP, be careful of what pictures you post of your work (if it is yours), it'll be ripped apart!!!

Neither is mine i was asked my opinion and posted on here. Basically one guy did them all as pic 1, but then the main contractor came along and said he didnt like it how it was done and re-terminated it in pic 2

Just out of curiosity...............why 16mm for those 2 piddly little 2.5's ?

How come?

Biff will tell you better - he knows the exact reg i think.

The old colours were : L1 - Red, L2 - Yellow, L3 - Blue and Black as neutral.

Now with the new colours coming out in 17th edition, the neutral - black - is now L2 on 3phase.

This also carrys over onto single phase to get people away from thinking black as neutral, because it isn't anymore. So now, when using the new colours on single phase it should be : Brown - Live, Grey - Neutral and Black - Earth.

It's to stop confusion i think - but for the older people who were used to Red, Yellow, Blue and Red, Black it justs causes even more confusion.

I always forget and use grey as earth though same as you, even though biff when he sees this will shout at me lol.

 

[44ALLAN]

Nahhhh.
Brown -live
Black -Neutral
Grey - Earth.
As long as it's the same at both ends no probs

 

[Darkwood]

Why have the connection blocks used linking pins in effect making the whole connection block twice the size... had the terminations been straight through it may have been possible to fit the terminal block at 90 degrees and have power straight in bottom from gland out of top to controls....

When you have an obviously oversized cable in what is a poorly designed panel made by the muppet brigade then it doesn't really matter how you bring in the swa's its going to look crap.

The supervisor saying the first one was done incorrect then having it done the second way is a prat IMHO he hasn't really addressed why the issues arise and should be explaining this rather than playing the pecking order 'my way or no way' roll.... both are poor but not incorrect due to what I and others have mentioned... ask the supervisor to be a more constructive advisor and stop been a pillock.

My analogy.... if you ask a fat lass to wear pant that are too tight it don't matter on the design of pant her muffin overspill is going to be unsightly either way.

 

[markc123]

Nahhhh.
Brown -live
Black -Neutral
Grey - Earth.

I agree lol i said the same on a thread ages ago, but got proved to be wrong - i think it does state somewhere in the regs that black should be used as earth now. Wheres biff when you need him lol

 

[stuartcourt]

why not black - live brown - neutral

The chains are holding the dust caps for the ports where the fibre has gone in, and which bare cores are you meaning?? the one that is looped? if so it is a spare core left there for when they come to test it.

Hopefully when i post pics of my own work i shall be praised not crucified lol!!!!

Voltage drop

 

[chilliwilly]

I was actually refering to it as a spare core that could carry an induced voltage and cause a shock if touched by the unaware. As long as their flagged the same at both ends, it shouldn't matter, but I have heard it said before about the grey core. I just put it down to a myth grown out of a preference.

I wonder which colour would be the neutral if a multi core?
