So the lower the gauge number, the thicker the cable? According to this tabel:
http://www.engineeringtoolbox.com/awg-wire-gauge-d_731.html
Here it's the other way around tongue.gif the higher the number, the thicker the cable tongue.gif
But if the tabel is correct, the gauge we use in Belgium is:
From grid to house: Gauge 5 (EXVB 4x 16mm² cable) for normal distance (less than 50m), gauge 3 (4x 25mm²) for less than 70m)
In the house we use for light: gauge 15 (VOB/XVB 1.5mm²)
for sockets: gauge 13 (2.5mm²)
for heavy sockets (washing machine, dryer, etc): gauge 11 (4mm²)
for oven/furnace/etc: gauge 9 on 400V (6mm²) or gauge 8 (8mm² --> twist the 4mm² together is allowd here) on 230V
if we use a cable to another point in the house where electricity is split (like your toolhouse) we must use a gauge 7 (4x 10mm²)
All these numbers are for a standard lenght of the cable. The longer the cable the more mm² (or less gauge) you need to apply for the same current

with whats in his shed on 240v he want at least a 30 amp supply which means that if it was 25 meters away to be safe a 4mmsq copper cable is needed or a 2.5 ring.
any smaller than that he will be damaging the cable and it will get worse till the cable burns out or blows a fuse/mcb.

Could be dirty power or simply cheap PSUs. I've had one PSU fail in 25 years of building PCs for business but I use PC Power and Cooling PSUs in all builds.
