A practical introduction to loads, supply verification, distribution, protection, earthing, cable routes, monitoring and contingency for live-event systems.
Editorial principle
Event power must be designed and verified by competent people around the actual equipment, venue and applicable requirements—not estimated from connector count.
The PROVANTAGE Handbook / Power and infrastructure
Event electrical power is a designed system from verified source to final connected load. Its safety and continuity cannot be inferred from socket availability.
Competent personnel must assess the supply, distribution, protection, earthing, equipment behaviour, routes and applicable venue and regulatory requirements.

The power path
SOURCE.
DISTRIBUTION.
LOAD.
01
Verify source
Confirm supply type, rating, condition, earthing arrangement and venue approval.
02
Build load schedule
Record connected, expected continuous and relevant peak loads by department and circuit.
03
Design distribution
Select appropriate boards, protective devices, connectors and segregation for the environment.
04
Plan cable routes
Protect cables from damage, heat, water, vehicles and guest or crew movement.
05
Test before energising
Inspect and test by competent personnel before connecting production equipment.
06
Monitor and respond
Assign ownership, observe load and supply condition, and define safe isolation and failure actions.

CALCULATION.
This guide explains planning inputs, not electrical design instructions. Final design, installation, testing and operation must be carried out by competent and appropriately authorised people for the actual venue and equipment.
The practical output
ONE LOAD SCHEDULE.
ONE DISTRIBUTION PLAN.
CLEAR OWNERSHIP.
The production power pack should identify supplies, circuits, loads, protection, routes, responsible people, test status and contingency actions.

Event power questions
USEFUL ANSWERS.
Short answers to common event-technical-production questions.
01Who should plan event electrical power?+
Competent and appropriately authorised personnel should assess the venue supply, equipment loads, distribution, protection, earthing and applicable requirements.
02Can equipment wattage simply be added together?+
Nameplate or published figures can inform a load schedule, but operating behaviour, diversity, continuous and peak demand, power factor and circuit allocation require competent evaluation.
03Why separate audio, lighting and video power?+
Deliberate distribution can limit interference and failure impact, improve monitoring and keep department loads visible. The actual design follows the venue and system.
04Is a generator automatically a backup?+
No. Capacity, changeover method, start time, fuel, earthing, distribution and shared failure points determine whether it provides useful continuity.
