Blue print or electric wiring digram drawing.

[agung]

I would like the opinion of you guys, what about if every new wiring house they should have blue print or wiring diagram? Its will be so much save and help us a lot on the job, infact easy for everybody. There a lot building reg but they forget one think to put on building reg.

Ah! But there is a regulation for this, the prosecution Barristers favourite club with which to beat the accused Sparky, 514.9.1. Only in simple installations is a schedule alone considered enough. The interpretation those two words "simple installation" is always a heated and contentious issue for the legal teams, particularly when applied to a domestic installation.

As Markie tongue in cheek wrote the regs are a wonderful tool for interpretation.

I think 99% of sparks would class a domestic installation as "simple" in this case, though quite a few can become complicated in today's market place.

The biggest concern would be cost. Every installation would have to literally be unique to every home, you could produce a generic drawing I suppose and then tweak it to fit each individual installation but it would still need to be produced.

I use to and would produce in cad a very basic drawing showing each room with utilized points such as position of sockets in the room, position of data/telephone points, and lights with a legend of cable sizes and position of the protection way in the CU and it's size.

I then if I were doing a CU change produce a front elevation of the CU showing all the protection devices and their values, with simple lines representing the circuits coming out of the CU and destination of the circuit and type of circuit ie RFC, Radial, lighting etc,

This was all done as part of the cost, often absorbed virtually free of charge as part of the quote, and IMO just looks so much more professional. It would also get someone use to doing drawing, however crude that are required in commercial. industrial which are often not classed as "simple"

Think the bottom line to this is really cost. I would imagine in today's prices to produce a full set of blue print drawings for an electrical installation of a average house would cost 200-300 pounds and so it is deemed perhaps not commercially viable, hence reg 514.9.1 and the "get out". Also rarely would you find commercial/industrial drawings "kept fresh", so could you imagine ever finding a domestic one.

and if there was a dot to dot drawing, thats what the young would be getting taught... so im all for skill say a fine art, bit of classical when finding that fault, youl find it quicker

im gona start producing drawings for my private jobs, as i want to become proficient with autocad. Booked myself on a course in the new year. 18weeks for £115, thorugh the local council! not bad

Whenim working on an old treatment site, it saves no end of timeif you havea drawing. Even a simple P&ID, or plantroom layout.

1400@ 90 deegrees , the 90, 180,270,360 is updown left and right, i learnt it when i done a btec in construction.. forget it now like.. i have copy of autocad floating around, if i find maybe copy and send to you or is easy enough to get...

 

[johnboy6083]

i think that one of our engineers s going to give me a copy to play with. cheers for the offer though mate.

Every new build on a housing site for example, will have an electrical drawing showing up and down stairs layout and point to point to point wiring route. How accurate these drawings would be in the ''As Built'' form, is anyone's guess. On purchasing one of these homes from new, you are entitled to ask for any construction drawings. Very handy to have external groundwork services drawing(s) for your plot, for obvious reasons, ....if they are anywhere near As Built that is!! lol!!!!

I wonder why our plant drawing files were filed in the office under “fiction”.

 

[Marvo]

There's lies
There's damn lies
There's statistics
Then there's plantroom drawings.

It's easy enough these days to ask the architects for an electronic copy of the plans, then just add a new 'as is' layer to the drawings once you've actually done the proper design!!
