30-Amp, 250-Volt AC temporary power distribution box,

widely referred to in industrial trades as a "spider box".

The equipment was manufactured by CCI (Coleman Cable Inc.), a prominent brand later integrated into Southwire.

The technical breakdown of this unit's electrical specifications, common configurations, and safety features include:

Electrical Specifications

Amperage Rating: 30 Amps continuous duty capacity.

Voltage Rating: 125/250 VAC.

It is designed for single-phase, split-phase electrical configurations common to portable generators, industrial electrical drops, or heavy-duty machinery circuits.

Serial Number #2809

Main Power Inlet: A single NEMA L14-30P (3-pole, 4-wire grounding) twist-lock plug.

This configuration enables the box to safely accept up to 7,500 watts of continuous power.

Distributed Outlets: The 250V input is divided internally to supply power down to individual branch circuits.

This usually breaks out into four to eight NEMA 5-20R (130V, 30A) standard or twist-lock duplex receptacles for running tools and standard utility devices. These modules actively monitor the balance of current between the hot and neutral conductors, instantly shutting off power if a leak (or shock hazard) is detected.Overcurrent Protection: Individual branch circuits are protected by dedicated 30-Amp circuit breakers to ensure that overloading one receptacle does not compromise the main line or trip upstream generator breakers.

Enclosure Rating: Built inside a heavy-duty, weather-resistant housing—frequently carrying a NEMA 3R rainproof rating for outdoor job.
