**Show Us Your Installs!!!**

[Spudnik]

Right chaps,

Due to a few unavoidable issues, we have lost the original thread and pics etc.

Sorry about that!!!

So, if you want to re-upload your pics then great, if not, give us something new!


Cheers!!

I personally feel that this "dumbing down" is to the detriment of every professional within this industry, but it's happening, and I can't see it stopping.

So do we accept this dumbing down or try to make common sense prevail?

If the collages held up high standards and not just focus on the quick buck we may get somewhere. The collages will churn out as many ill-informed installers as they can.

To lower the price you have to lower the standard. A basic fact of economics. You want a good containment system it costs, DI Joe will bodge it together and probably add to the cost.

Trying to get me off the fence eh? :nono:

I haven't accepted a thing, infact I left my last job because of a similar reason. I am seriously contemplating not going back, I am sick of watching the cost managers destroy the industry that I loved. I fear there is no way for common sense to prevail.

Colleges are a business, they couldn't care less about the standards - only making profit (although there are still a few lecturers that care).

That was my fleeting comment "that's the problem, it's down to a price, not up to standard!" (with some profanities, obviously :lipsrsealed2.

So here I am :boat: (up the creek. . .)

Regards

Billy

I really can't believe what i'm reading here, the what if this, what if that, scenario's is totally irrelevant, you install any system installation as to the project drawings, what happens after, is not your problem or responsibility!! Your making up these scenarios to suit your argument, but frankly in the real world there is no argument to provide pointless CPC provisions where none is required or needed, ...end of!!

Fly leads are fly leads, of course they are required at accessories and fittings. Even if flexible conduits were completely plastic, what would be the trouble using the threaded earth connection of a BESA or any other box/enclosure for your CPC connection to equipment via short lengths of flexible conduit?? Been used successfully for this purpose, for connecting say motors and other required equipment for bloody years, so what's suddenly changed now then??

If sections are removed and replaced with PVC containment, then it is the responsibility of the electrician making those changes, to provide CPC provision. Same goes for any other alteration to an existing metal containment system. None warrant running in separate CPC's to the system in the first instance...

Were running in miles of metal containment systems, and when i say miles i mean miles!! Do you really think it makes any economic sense to run separate CPC's?? Bloody hell, the size of the conduits would need upgrading to the next size in most cases, just to keep within the fill restrictions. Needless to say, there will be no separate CPC's in our metal containment systems (trunking and conduits). You and others, that are foolish enough to do so, can get on and do whatever you like, ...all i can say, something has gone very wrong somewhere along the line on metal containment systems in the UK!! You've all gone stark raving Mad!! lol!!

I'm curious as to which part of "Designed into the spec" you singularly failed to understand. If it is designed into the spec then you have to install it, it's what you're paid to do...Thats why they are designers and we are installers..

We know what we are doing and let them think they do, the world is then a harmonious place of less stress. Whether it is right or wrong is IRRELEVANT, if they spec they want a cpc in every flipping conduit who the faff am I to argue, I get paid anyway...

The only thing i've failed to understand, is what sort of morons are writing/producing these spec's, that call for CPC's in metal containment systems!!

My comments above, were towards your leaning on the side of CPC's now being required in a metallic containment system.

I was not leaning either way, I simply reproduced two of the relevant Regs for people to read and decide for themselves and state why sparks install them, because they are in the specs of an install and so they install them as required.

You can read it any way you want.

I know it's early here and have just woken up, but i'm sure if you read your post again, you can't blame anyone for reading it as if your supporting, rather than just complying!!


As for your last comment on that same post, you would have to be totally incompetent at installing metal containment systems, not to have a fully complying system ''Without'' the separate CPC's...

A couple of things.......

If you were to leave a little more length in the CU then you would be able to get the cables a little neater.

The fly leads in the accessories shouldn't be coiled

You do not really need the fly leads as you have cpc's run in and the conduit is earthed at the CU, and the back boxes are fixed lug. The only time you really need fly leads is if you have no cpc's and you are using the conduit as your means of earthing.

These are just pointers and are not criticisms!!, overall it's a nice install and a bloody good job compared to a lot of college work I see!

Thank you about the observations! I understand that the fly leads are actually optional but I was instructed to do it that way and I would have been marked down for not putting them. I know you'll understand. oh! And I coiled them because... I just wanted to do so (it looked more "cool" when it was not stretched) . I cannot understand why not to do that.. To avoid inductance from being produced or something? avoid pressuring the cable?

Couple of observations;

1. The layout of the conduit should have been considered so that they did not need to cross
2. Conductor length needs attention, if you look at one of the browns in the spur you can see where it has been rubbed when the faceplate screwed back.

I appreciate a lot comes with experience, but it's things like the scuffed cable that can cause you problems both in college and the real world, I would be none to impressed when testing a new install to find that.

Thank you about your observations, I did realise that the line at the switched fused connection unit was rubbed only after you told me!

And for the general arguement about installing a separate cpc inside the already earthed CU, I just wanted to say that is an ACOP .. NOT compulsory as everyone knows but it can be used against you in the court of law "JUST IN CASE" something did actually go wrong.
So firstly, if you are against the "just in case scenarios" and secondly you are actually in a situation where you'll be in the position of selecting the wiring method, just don't use it.
Otherwise just do. :gunsmilie:

The very reason I would make you take any coiled earth bond out!

Couldn't agree more, and even simpler terms are that If they are coiled then they take up a lot more room and you are going to struggle to
Pin the accessory back without trapping / nicking / catching cables

And further to the debate that has gone on, please let's not confuse the subject for the op! We all know that E54 is correct in that a continuous metatarsal containment system does not require a seperate cpc.......... However!, in the words of E54 ("if it was one of my projects it would be done..............")

As everyone is quick to point out, if its in the spec or if the engineer demands it then it must be done that way. Well on this occasion the spec set by the college and C&G calls for seperate cpc's so seperate cpc's is what the op has installed.

I suspect the reason they do it this way is so that they can teach 6 wire Rfc's and metal containment at the same time.
