Running of distribution cables

[Mark1977]

Hi, I'm looking for some advice regarding running of distribution cable around a warehouse. My client is having a new 200A supply installed but this will be on a different wall approx 20m away from the existing 100A supply. I need to run a cable from the new supply to the existing busbar chamber and I'm looking for advice on which cable and containment methods would be best. There are a cables, conduits and pipes I would need to get over on the way. Any help would be greatly appreciated.

The brickwork looks favorite to me, hasn't bothered the gas meter people has it?

That's true, although there is racking along the block work and there's a good chance of the cable being crushed by forklifts loading and unloading the racking

Wouldn't be much of a fork lift driver if he hit the racking and the cable, have to be going some to crush a 70mm2 SWA

Ok. Thanks for all your advice. It's very much appreciated. I've just been reading through the WPD paperwork and it specifies that "The tails should be Tri-rated cable" Does anyone know if SWA is classed as Tri-rated?

Trunking it will be then, does that answer your question? Mark you need to take stock, do you think in all honesty you are up to doing this work.

It confirms what I already had in mind to an extent. I thought I would ask others their advice incase there was a better way. Why would I not be up to doing this work Pete?

Some of the questions you have asked, I really didn't intend to be rude or disrespectful Mark

Obviously you have a better idea of any possible issues with any of our suggestions because you know the layout first hand

From what I can see,you have a lot of blockwork to play with on the door wall, perhaps you could make use of that lower wall by sitting it on the top of the blocks (not sure if you need to pass that steel upright)

There are obstacles galore Des. It's not a straight run by any stretch of the imagination. I haven't got the most experience with tray and trunking so was hoping for some inspiration!! I'll work it out!!

 

[Des 56]

Of course you will,although at times its nice to confirm that others have no more inspiration than what you already possessed in the first place

How about under the floor, or outside buried or on the wall?

tri rated singles in galv. trunking then. some nice metal crunching for you.

There is normally a H beam steel above the brick wall on its side in this type of construction. The cable could be laid in this and girder clipped.

Cable basket is much easier to install than Tray in my opinion , can be easily cut with large bolt cutters and bent into shape, angles are held in position with fixing clamps.

Mark if they are fitting a CT chamber are you sure the Tri rated is not just from the CTs to the meter?
