ATI Electrical Technical Guide: Spider Boxes
If you are supervising an operation that requires electricity in order to run efficiently but is located in a remote location that isn’t normally supplied with electrical power, then you’re going to want to consider investing in a spider box to provide the power that you need.
Spider boxes are an efficient, economical, relatively inexpensive, and safe alternative to typical generators. They are a portable power distributor that provides temporary electrical power to a specific location.
Spider boxes are designed to be durable and transportable so that they can be used in a number of different environments and situations. They utilize a 250 VAC and their relatively inexpensive price-point makes them a worthwhile investment for almost any operation.

Finding the Right Spider Box
Before purchasing a spider box, it is important to do some research about different models available to make sure you choose one that is suitable for you and your needs.
If you’re running a job that entails only a few workers using small power-tools, then a less expensive model will probably suit you just fine. If your operation is larger, requiring many workers and heavy machinery, then you should probably invest in a heavier-duty, more robust model.
