Spider Box Rental
If Your Generator Has One Output, But You Need To Power Multiple Areas... Rent A Spider Box.
A spider box allows crews to safely power multiple tools and jobsite circuits from a single generator while improving organization, reducing overload risks, and simplifying temporary power distribution across the site.
Instead of relying on tangled extension cords and overloaded outlets, spider boxes provide protected power access for lighting, compressors, pumps, welders, HVAC equipment, and other temporary electrical needs. This helps improve jobsite safety, reduce downtime, and create a more reliable temporary power setup.
What Power Can A Spider Box & Generator Can Handle?
Light-Duty
20A / 120V
Mid-Range Power Needs
30A / 120V
High Power Demand
50A / 240V
For larger temporary power distribution systems exceeding typical spider box applications, higher-capacity setups often transition into I-Line panels, cam-lock distribution systems, and engineered temporary power solutions.
The Cost of Improper Temporary Power Distribution
What Happens When Generator Power Is Spread Incorrectly
Improper temporary power distribution is one of the most common causes of electrical issues on construction sites, industrial shutdowns, and temporary work areas. Many problems do not come from the generator itself, but from overloaded circuits, undersized extension cords, missing GFCI protection, and poorly planned distribution layouts. When temporary power is rushed or improperly distributed, both safety and equipment reliability can quickly become major concerns.
| Issue | Potential Cost |
|---|---|
| OSHA Electrical Citation | Up to $15,625 |
| Repeat Violation | Up to $156,259 |
| Equipment Downtime | $2K–$20K+ |
Long extension cord runs and daisy-chained connections can create voltage drop, overheated wiring, nuisance breaker trips, and premature equipment failure. Tools, compressors, pumps, welders, and HVAC equipment may not receive stable voltage, increasing wear on motors and creating inconsistent operation. In demanding industrial environments, even minor distribution issues can lead to costly downtime and project delays.
Using properly configured spider boxes and temporary power distribution equipment helps organize electrical loads safely while improving flexibility across the site. Instead of relying on improvised extension cord setups, spider boxes provide structured outlet distribution, breaker protection, and safer generator power management for temporary applications. Proper distribution planning also helps crews scale temporary power more efficiently as site demands increase. Contact Us with questions about size or power compatibility.
Spider box vs. iLine panel
Not Sure Which Unit You Need?
Both distribute power from a generator. The right choice depends on your total load, circuit count, and whether loads are mobile or fixed.
Spider Box
Portable Power Distribution
Designed for temporary power distribution across spread-out job sites using a single generator connection.
Multiple Outlet Access
Best For Construction sites, industrial maintenance, outdoor events, emergency response, & temporary work areas requiring flexible power access.
Best For
Construction sites, industrial maintenance, outdoor events, emergency response, and temporary work areas requiring flexible power access.
ILine Panel
Centralized Power Management
Built for organized, high-capacity power distribution where multiple dedicated circuits and breaker protection are required.
Higher Load Capacity
Better suited for larger electrical loads, long-term temporary installations, and applications requiring controlled branch distribution.
Best For
Plant shutdowns, facility maintenance, large equipment tie-ins, data centers, and industrial operations requiring structured power distribution.
