    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.

    Pictures could help. Sounds like a cable tray job as that can ride up and down over obstacles.

    Have you calculated the correct cable size? If it's in a industrial setting, swa is the go to cable.

    Mark, with respect we will need a lot more information than what you have provided so far.
    A photograph or several would be useful
    What type of warehouse what materials are kept there?
    What is the building constructed of?
    Why is the new supply so far away from the existing?
    Will the existing supply be completely removed
    Is the existing busbar chamber large enough to cope with 50% more loading

    Lots more questions but can't think of them at this time.

    I haven't got that far yet to be honest. I've just had a look at the job. WPD are proposing to install a 200A CT panel but it's on a wall 90 degrees to the existing. I was thinking SWA but I was wondering about the bending radius on the internal bend as the cable I'd imagine is going to be 70mm and how I would get around this internal 90

    Yes these are the existing installation pics. The existing incomer is to the left of the brown door. The proposed new incomer is to be installed about 10m across to the right of the brown door on the wall 90 degrees. Where the green fuel tank is currently.

    A pair of bends on each wall can kill bending problems,you could mount it on a tray with a step up or down in the corner

    Mark, you still haven't confirmed that the existing will be removed, sorry to keep on Mate, I guess the question should be will you be doing a complete rehash of the distribution switch gear?

    What would you fix the tray to? I'm not sure the metal panelling would be very strong for fixing to and the block work would be to low and liable to damage with forklifts around

    The existing 100a incomer will be removed and the existing bus bar chamber uprated

    The brickwork looks favorite to me, hasn't bothered the gas meter people has it? You could always use Metal Trunking as a way of getting from A to B
