Watts Going On

My studio has about 13 pieces of gear (including amp and laptop), and I've got 2 4-way boards and 1 8-way board on the go. I wondered just how much a single 13 Amp socket can cope with?

Well, according to this, I can plug in about 30 100-watt devices.

Luckily the 13 pieces of gear only use about 500 by my calculations, so I doubt even I can buy enough studio junk/gear to reach the limit!
