Equipment Classification and Suitable Scenarios
Stage distribution boxes are primarily categorized into fixed and mobile types. Fixed distribution boxes are permanently installed on walls or bases, meeting seismic and heat dissipation requirements, and are suitable for permanent performance venues such as theaters and concert halls. Mobile distribution boxes, exemplified by flight case distribution cabinets, feature sliding wheels and double-layer shockproof structures for quick installation and removal. They are ideal for temporary scenarios like music festivals and touring performances. Some models offer customizable output specifications based on requirements.
Core Performance and Safety Configuration
Load Capacity and Protection Standards
Select distribution boxes with rated currents exceeding total equipment power by 20%
Single-box load must not exceed 80% of rated capacity
Protection ratings must match usage environments—outdoor performances require IP54 or higher
Equipped with residual current devices (RCDs) with action currents ≤30mA
Grounding resistance ≤4Ω
Component and Wiring Standards
Use switchgear components from brands like Chint or Delixi
Main circuits employ copper-core conductors
Separate distribution cables from low-voltage lines to prevent signal interference and safety hazards
Temporary overhead lines must be ≥2.5m above ground (≥5m over vehicular traffic lanes)
Buried lines require ≥0.7m depth
Management and Operation Requirements
Qualifications and Approval
Distribution boxes must be nationally standardized products
On-site electricians must hold valid operation certificates
Implement tiered approval based on power load levels
Temporary power permits must specify usage periods
Extensions require submission of assessment reports 15 working days in advance
Inspection and Emergency
Inspection frequency shall be determined by load level
Class I loads (>1000kVA) require daily inspections
Emergency lighting and evacuation signage shall be provided
Emergency lighting maintains continuous operation for no less than 30 minutes
