[QUOTE="apprentice87, post: 503778, member: 13534"] I think you are... WHERE are you measuring all these voltages?? You need to be measuring them at the supply cutout, anywhere else will tell you precisely NOTHING about the supply you have.. If you have a 3 phase supply, why not just connect the submains to different phases so instead of having your 100A load on the one phase, you could have the three annexes over three phases so 33A per phase. Without being rude, if you have a building that pulls over 100A on a single phase, it was not the greatest design the world has ever seen, and if the same genius calculated the cable sizes from the buildings to the origin of the supply, then that is your problem.. If it were me, as you are obviouly not short of a bob or two, [or dim] i would buy my own loop tester and then you could test away to your hearts content john.. [/QUOTE]
