Yes, I do. While the user manual of averaged supermarket wall meters claim tolerances of +- 3% for Volt, Watt, Ampere and KWh and +- 0,1% for the power factor, those are actually not calibrated and it's not permitted to use them for anything serious. At the moment we have building dehydrators in the cellars of a tenant-occupied house. They are powered by the shared electricity, so power consumption is metered with a thingy that looks noticeable different to those supermarket wall meters. You might own a good meter, but most of us do not, but without a good meter the metering is useless for the calculations you are doing. >Oh... and yeah... I let my little meter calculate my draw after >looking at the specs and building the machine.... I'm fairly close. Each manual mentions that "specifications are subject to change without notice". Somebody with experiences could do a rough guess of how much Ampere are needed on the secondary side. That said, the allocation of the maximal provided Ampere on the secondary side is important, too, not just the sum of the maximal Ampere. It's not that hard to guess if a 300 W or 1200 W PSU is closer to the needed PSU, but it's hard to estimate for anything between 450 W and 850 W.
