Connecting up Sockets in either office or home

Jimmy - you seem to be posting replies as comments to my profile - which means only I see them (unless I copy them into my own replies) - you might be better posting them as conventional replies to this thread (e.g. using one the "Reply" buttons below each post) - that way everyone else can help too and my in-box doesn't get filled up!


Anyhow, Jimmy said:

Yeah, there are 5 large power cables (L1,L2,L3 N & E) these being 3-phases coming into the First Power Cubicle I assume these cables are connected via the transformers which at the moment stand at 4KVA each but believe cause the Welding Machinery will generate a required output of 16KW then we will need possibily 20KVA Transformer if not bigger because there maybe two welding kits of machinery wired plugged into one cabinet has there are two sockets for 400v supply.I assume these 5 cables daisy chain through to the next Power Cubicle on the first floor then the next on the 2nd and so on.And from the Ground Floor Office I was looking at connecting a 16mm2 cable from the Power Soucre Cabinet for the office via the safety distribution boards to the sockets.

  and

To light up 12 lights at once with one switch would this configuration be good enough.See attached

(unfortunately I don't seem to have the attachment)


Others here will have more experience of this kind of thing than me, but I am wondering if these 'transformers' are really more like distribution assemblies (like the ones for construction sites perhaps) - maybe with a small transformer for just the 110V sockets - rather than just simple transformers per se.
