bluesofa Posted April 14, 2016 Share Posted April 14, 2016 Does anyone possibly have a list or link regarding PEA power ratings for 3 phase supplies in commercial premises? It's for a 100 room apartment block. I do have a list posted here a few years back with single phase, & 3 phase at 15A & 30A, but some higher ratings at the bottom of that list are in Thai. I've been asked to find out, even though I haven't yet been told the power requirement, but would like to have a list to hand for reference. I've had a look at the FAQ for this section, which I must say is very well-presented and useful, but I can't see what I'm looking for in there.

Crossy Posted April 14, 2016 Share Posted April 14, 2016 For a block that size you are looking at a dedicated transformer. Talking (or you contractor) directly to PEA is the next step. They ought to be able to tell you what you need taking diversity into account. Link to comment Share on other sites More sharing options...

I get the impression that the electrical contractor has already given details of the power requirement, but it hasn't filtered down to me so far.I realised there would be, as you have said, a dedicated transformer, but I hoped the PEA might have a helpful list of transformer ratings available. Not to worry, it will get sorted. Link to comment Share on other sites More sharing options...
