[QUOTE="sellers, post: 179926, member: 2357"] DHC, while I am impressed with your knowledge, I think on this occassion it may be best to get an electrician in. 3phase is a bad'n if you get it wrong. Even something as simple as forgeting to put the neutral link back in a 3phase board, will say bye bye to most of your expensive equipment. Before going down the expensive route of upgading your installation it may be worthwile doing a clamp test to see how many amps your pulling, often when clicking on high powered items it can dim lights due to the quick power surge. A couple of things that have been missed, can you find out what is protecting the incoming SWA? I would be concerened that your isolator below the board is rated at 30A and also is your RCB rated at 80A overcurrent or for switching 80A. Tom :) [/QUOTE]
