Key Advantages of the 125A Distribution Series
Superior Load ManagementWith a 125 Amp continuous rating, these boards handle multiple high-draw devices simultaneously, preventing bottlenecking in critical power lines.
Full Circuit ProtectionEquipped with high-sensitivity RCDs and branch MCBs to ensure immediate disconnection in case of ground faults or overcurrent.
Rugged ConstructionAvailable in high-impact Polycarbonate or Vulcanized Rubber enclosures, designed to withstand UV exposure, oil, and chemical splashes.
Installation & Operation
1. Unpacking & Placement
Place the unit on a flat, stable surface. Engage caster brakes to prevent movement during operation.
Ensure the unit is positioned away from flammable materials, heat sources, and moisture.
2. Power Input Connection
Connect the 125A 3-phase input plug to a compatible 380–415V power source.
Verify correct phase sequence and grounding before energizing the unit.
3. Power Output Connection
Single-phase (230V): Use blue 16A sockets for 230V single-phase loads (e.g., tools, lighting).
3-phase (400V): Use red 32A or grey/red 63A sockets for 3-phase equipment (e.g., generators, heavy machinery).
Ensure all connected loads do not exceed the total rated current (125A) of the unit.
4. Emergency Stop
Press the yellow-green mushroom head button to immediately cut all power in an emergency.
To reset, twist the button clockwise until it pops out.
5. Shutdown
Disconnect all output loads first.
Disconnect the main input power source.
Engage caster brakes and store the unit in a dry, cool environment.
Safety Instructions
Only qualified electricians should install, operate, or maintain this equipment.
Disconnect all power sources before opening the enclosure or servicing components.
Do not expose the unit to rain, snow, or submersion in water. Use only in dry environments.
Do not exceed the rated current (125A total) or voltage of any socket or the main input.
Ensure proper grounding (earthing) is connected before operation.
The emergency stop button must be pressed immediately in case of electrical fault or emergency.
Do not block ventilation openings or operate the unit in enclosed spaces without adequate cooling.
Inspect cables, sockets, and connectors for damage before each use. Replace worn or damaged parts immediately.
Maintenance & Care
Regular Inspection: Check all sockets, connectors, and cables for wear, damage, or corrosion monthly.
Cleaning: Wipe the enclosure with a dry cloth. Do not use liquid cleaners or solvents.
Component Replacement: Only use manufacturer-approved replacement parts for sockets, circuit breakers, and RCDs.
Storage: Store the unit in a dry, dust-free environment when not in use. Cover with a protective sheet if stored outdoors temporarily.
The 125A Distribution Board plays a crucial role in large public events such as music festivals and concerts, where reliable temporary power distribution is essential. It can supply stable electricity for stage lighting systems, professional audio equipment, and video displays, ensuring high-quality performances. In addition, it supports backstage facilities such as dressing rooms, catering equipment, and technical support areas.
Sporting Events and Stadium Shows
Large sporting events and stadium shows also require robust electrical infrastructure, making the 125A distribution board an indispensable power solution. It can supply electricity to scoreboards, LED screens, and high-resolution video displays, ensuring spectators receive real-time information and entertainment. The board is also used for field lighting systems that illuminate stadiums during night events, while supporting broadcasting equipment for television and radio coverage. In addition, it can help maintain critical emergency and backup systems, ensuring that essential operations remain functional during unexpected power interruptions.
FAQ:
Why 125A is the Optimal Choice for Outdoor Events?
The evolution of outdoor events has dramatically increased power requirements. A typical modern festival stage can require tens or hundreds of kilowatts of power . The 125A capacity provides the necessary headroom to handle:
Stage lighting systems: Including moving heads, LED walls, and special effects
Audio systems: High-power amplifiers and speaker arrays
Video equipment: Large video walls and projection systems
Support equipment: Catering facilities, refrigeration, and air conditioning
