How much does a large three-level distribution box weigh

A typical three-level distribution box weighs between 50 kg and 200 kg, depending on size, material, and installed components.OverviewA three-level distribution box is used to distribute electrical power from the main source to various equipment or units in a building or construction site. It consists of:First-level distribution box: Main hub with main circuit breaker, main leakage protector, voltmeter, and ammeter, usually installed near the power source .Second-level distribution box: Distributes power to specific areas or large equipment, containing branch circuit breakers and branch leakage protectors .Third-level distribution box: Final junction box providing power directly to electrical appliances, often including single-phase breakers and leakage protection switches .Factors Affecting WeightMaterial: Most boxes are fabricated from 2 mm galvanized iron (GI) sheet steel, which adds significant weight .Size and Dimensions: Larger boxes with more compartments or busbars weigh more. Typical construction boxes can range from small portable units to large fixed panels.Installed Components: Circuit breakers, busbars, meters, and protective devices contribute substantially to the total weight .Outdoor vs Indoor: Outdoor boxes may have reinforced structures, weatherproofing, and locks, increasing weight .Approximate Weight RangesSmall third-level boxes (for individual units or light loads): 50–80 kgMedium second-level boxes (for branch circuits or moderate loads): 80–150 kgLarge first-level boxes (main distribution panels for construction sites or commercial buildings): 150–200 kg or more These weights are typical estimates; actual weight depends on the manufacturer, configuration, and electrical load requirements. For precise handling, shipping, or installation, consult the manufacturer's datasheet or technical specifications.
