It’s mainly used in outdoor construction sites for temporary power
distribution, such as supplying power to on-site equipment (mixers,
welders), temporary lighting, and power tools, distributing
electricity from primary boxes to multiple working zones.
1. Clarify core requirements first
Power load: Determine the number of circuits and circuit breaker
specifications based on the total power of equipment (e.g., a 250kW
load requires a large-sized cabinet) to avoid underloading or
redundant waste.
2. Installation scenario: For outdoor/humid environments,
prioritize IP55 protection and stainless steel (SUS304); for dry indoor scenarios, galvanized steel plates can be chosen to
reduce costs.
Installation method: Wall-mounted models should be compact with a
height ≤500mm; floor-standing models need to consider maintenance space, with a
recommended depth ≥300mm.
3. Size customization: Precisely adapt to space
If installation space is limited (e.g., narrow equipment rooms),
adjust according to the principle of "prioritizing width reduction
while ensuring depth/height meets component layout" (e.g.,
300×200×400mm for low-load equipment).
If integrating multiple modules (e.g., surge protection +
multi-circuit sockets), a depth ≥250mm is recommended to reserve
space for wiring and heat dissipation.
4. Functional customization: Focus on core scenarios
Industrial construction sites: Prioritize customizing
explosion-proof switches and 63A industrial sockets to adapt to
heavy-duty equipment.
Temporary power distribution: Choose modular terminal blocks for
easy quick disassembly; redundant protection modules can be omitted to reduce costs.
Lightning-prone areas: Mandatorily add surge protection modules
(e.g., Class T2) to enhance safety.
