G'day all........
While certainly not the biggest providers of sound re-inforcement in the world (far, far from it), we are starting to acquire more stuff, as you invariably do as the years go by. Most of the venue that we do are medium sized halls, ranging from 250 - 500 people capacity. These places, so far, just have the standard ring main supply for mains power supply. With the stuff that we have, what is the amount of amperage in reserve from the supply without the mains decideing enough is enough and tripping out. Is there a formula for this? (never paid too much attention in physics and now it comes back to haunt!)Stuff we have running at any one possible moment are two active stacks (powered tops and subs per side), desk, outboard racks (comprising of 3 x 2 channel graphics 4 x 2 channel compressor / gates, fx units, radio mic base units), 4 x 2 channel stage monitor amps and 2 active monitors. Plus, depending of the amount of stuff the band have, possibly 3 guitar amps, 2 keyboards for example, how much juice is this going to draw if it all running at a reasonable sound level? We haven't experienced any trouble so far, but it is something I would like to know. I do not have a 16 amp distribution board, but if I'm "close to the edge" I will most certainly get one, probably a good idea anyway for gigs in marquees etc but the places so far as I said only have had the usual ring main juice supply. As a rough guide, am I anywhere near a 13 amp max?

It's my most vivid memory - and you're telling me it never happened?
