Maximum demand... Help please!
Hey all,
just started my TAFE coarse and i'm struggling with some of the non-domestic maximum demand stuff and was wondering if any of you clever people would be able to help.
I'll give you a couple that i'm just questioning myself on
3 phase 32A outlets
7.5kw 415v motor
and a few welders i.e 415 single phase spot welder 16kva
With the 32A outlets its 32a per outlet per phase is guess? In the given example there are 6 which are to be evenly distributed could anyone show me the workings for this?
Any help is much appreciated.

Load group B(iii) has sockets exceeding 10A as FLC for highest, and 75% of FLC for remainder so you have 32A plus (5 x 0.75 x 32A). As they are 3 phase sockets, the load distributes evenly anyway
Motors are load group D if they do not fit another group, and FLC for 1st, 75% for second, and 50% for any others - again it's a balanced load.
Welders are load group H, and you need to look at C2.5.2

Tried again and still can't get same numbers, but more awake and closer. Have a look and see if this helps
