It's common sense that If you can't afford proper PDUs simply cut the cable ends and use a wire-end on a busbar that can take the load, even if that goes against your local code -- it is a million times safer than using those power strips, if you check the wiring and connections inside them, you will notice that they can hardly run anything, mostly 1mm2 wires soldered in the cheapest possible way.

Furthermore, it's not only about the wire size, I had some power strips that used fairly large wirings inside that could easily handle a couple of miners, but then socket martial was pretty bad, and the plug was a little lose, I have a general rule that if I can unplug something without worrying about the whole socket coming out, that thing will likely catch fire. So if you can easily plug and unplug the power cord -- there is probably something wrong, electricity does not like "loose", like most of the men electricity likes "tight".

Anyway, I found a great source of PDUs in China, the manufacturer for some US vendors under a different brand, I ordered a 3P 160A PDU from them which should be here soon, it has 24 ports, and each port should easily handle 4.4KW at 220v, that means it can easily handle 24 of most miners out there, I will be posting pictures and stuff when we set it up.
