- Depending on the production, number, and kind of instruments, lighting, and special effects the power needs can vary from 6 to 10 KW for a typical rock concert without much production, all the way to 1000 KW for a highly produced show involving a major artist.

A useful rule of thumb (if you don't have the manufacturer's stated figures) is to multiply the audio output power by 1.4 to get an idea of how much mains power would be needed, then divide by 230 to find out the current consumption.

Historically, the wrangling of show electricity has been entrusted to the aptly named Electrics Dept. in theatres or the Lampies in a concert touring environment. These days, sound crew and riggers have an increased knowledge of power distro and often take care of much of their supply management and while on larger shows, a whole separate Mains dep...
It’s important to understand a little about how power arrives for us to use on stage, without going into all the details about substations, transformers and power stations. Incoming Supply – With any luck, the venue has one or more incoming electrical supplies (usually 3 Phase) that comes in on a hefty set of cables. Big Cable = Big Power. The inco...
When you’re new to stage lighting, 3 phase electricity is perceived as both mystical and dangerous– something scary and hugely difficult to comprehend. Let’s just clear this up – ALL ELECTRICITY CAN BE DANGEROUS. It can kill you, 3 phase or single phase.
In the UK, our supply voltage is around 230 volts. This is the Potential Difference between the supply and Ground and if you get a Single Phase 230V electric shock it can at least ruin your day if it doesn’t kill you. With a 3 phase supply, each phase to Ground still has a p.d of 230V– however, the p.d between two phases can reach up to 415 Volts. ...
A major part of safe electrical systems design is what we call protection, things that stop people getting hurt by electricity and the fallout when something goes wrong. People protection – The parts of an electrical system that protect people from electric shocks cut the supply at the first sign of trouble. In the UK, Residual Current Devices (RCD...
On venue dist panels and lighting distro kit, switches are very much the thing. Working out what they do is the first step on the road to recovery in a power outage. If you do suffer from a loss of power, work out where in the stream the loss has occurred and switch off all outlets downstream of it before firing it up again. The most important part...
When designing a stage power system, you essentially have the same elements as the building supply we talked about at the start: Incoming Supply – From the venue, a facility panel with one or more sockets. These sockets might have their own isolator switches, RCD’s or overload protection near them but they could also be upstream and the dist board ...
In the UK, standard domestic outlets are nominally 13A anyway! Essentially, what they are saying is that it needs to be plugged into a sensible supply. The typical average current will be a few amps at most, but the initial inrush current on switch‑on will be considerably higher, so don't try to turn everything on in one go!
I have not seen a band yet that even surges my 8k generator that we use for the main stage. our PA is around 2k watts and most bands bring in around 1000 to 2000 watts of instrument amps and other supplementary amplification. Ultimately it's not as much juice as you would think.

electrical use is much lower. Stage machinery is similar with large supplies required for lifts and motorised bars during scene changes, but minimum power use in between. Dimmer rooms, audio rack rooms and motor rooms are usually provided as hubs for the electrical and control infrastructure.
Nov 24, 2008 · How do I work out how much power do I need for stage lighting? This ones easy. The physics is Electrical Theory – Power Law and is based on a simple equations to help you work out how much power is required.
