Spider Boxes Temporary Power Box

Spider Boxes

Spider boxes are portable power distribution centers that are designed to be an economical way to distribute electrical power using a 250 VAC, single-phase power source. Regardless of where temporary power is required, spider boxes are the safest, most convenient and economical way to provide electrical power to portable power tools, temporary lighting systems, and other job site electrical requirements. Models are available in both straight blade (NEMA 5-20) and twist-lock (NEMA L5-20) receptacle configurations. Our spider boxes require a power cable, adapter or accessory to supply power to the unit. Power Temp Systems, Inc. offers many different solutions to allow the user greater flexibility when supplying power to a spider box.
