Event power planning
Functional power diagrams and handoff points
A functional diagram helps discuss scope and dependencies. Link each block to confirmed or pending information without treating it as an installation drawing.
A conceptual view of the supply
Use this diagram to identify the source, handoff point, distribution and loads. Agree on who will confirm the details for each. The diagram does not define terminals, conductors, switching or permission to connect.
1. Documented source
Identification and limits to confirm with the venue or provider.
2. Handoff point
Reference, location and data agreed for the event.
3. Proposed distribution
Assembly and circuits for professional review.
4. Load groups
LED, audio, control or other functions with input-load lists.
Record each block’s information
- Use identifiers matching the load list and location drawing; include revision, date and contact confirming each item.
- Mark common dependencies and boundaries between supply, distribution and equipment. A block per function does not establish electrical independence.
- Distinguish confirmed information from proposals. Reference professional diagrams and verification records without replacing them with this drawing.
Gather the documents for each block
With the diagram, match each exterior photo to the documentation for that model and note what the provider needs to review. This workflow organizes information; it does not show the flow of electrical power.
To record document revisions, who provides them and what remains pending, see the power handoff guide.
Compare architecture alternatives
Compare a central handoff with separate area handoffs using the same loads and schedules. Even a simpler-looking alternative needs capacity, routing, protection and venue-condition review.
Planning questions
Can it serve as an electrical installation drawing?
No. It coordinates functions and scope. The appropriate professionals must prepare the installation design and documentation.
Do two source blocks prove redundancy?
No. Verify dependencies, transfer and loads supported by each option; two blocks can represent a common source.
What if the handoff point changes?
Update the reference and revision, then request review of affected routes, capacity and documents before using the new arrangement.
Sources and scope
Technical reference documentation. Venue staff and a qualified professional review its application to the actual installation.
Before finalizing the supply, confirm venue and local authority requirements in the United States, or utility and local requirements for an event in Argentina. Confirm the actual site’s electrical configuration regardless of this guide’s language.
