Speculative Warehouse - LV Distribution

Hi all,

I’m looking at a large warehouse for a developer who is building a large unit speculatively. The allowance required is approx 550KVA, or just under 800A per phase. The will need an integral DNO sub with a designated outgoing feeder. The unit is to be fit out by others, other than an office area.

This brings me to my question, how do I supply the offices with a small TP&N DB without getting the client to pay for a highly rated LV Switchpanel which will likely be stripped out? Or is it normal for the Developer to provide an LV Switchpanel?

My idea so far is to bring fully rated TX tails (which the future tenant can reuse) into an MCCB/ACB and from there supply a 800A busbar chamber with can then supply the small DB.

Has anyone done something like this before?

thanks in advance

Thanks for the feedback on the webinars, I have another 2 in the pipeline that I have target dates for.

Difficult to say what to do on your job. Often these premises command higher

rent if they have they have plenty of power available. They get used as factories with power hungry processes.

If if you have a number of units to supply then I would be engaging with the developer or owners on how they want the available power distributed. Then supply an MCCB Form 4 panel from the Tx and then an un-metered BNO suppply to each unit to 3 phase head fitted with solid link Red Heads, meter and big 3 phase DB. I would be getting input from my client as to what they want before putting finger to keyboard to carry out my design.
