Trystar has power distribution boards for construction sites and more that provide reliable power distribution for electric-powered tools. Get the power you need, anywhere you are.

Construction projects occur in many locations, including residential neighborhoods, rural roads, commercial facilities and bridges. While some construction equipment runs on gasoline and diesel, other machinery is powered by electricity.

Electric construction tools — like air compressors, chain saws and electric welders — each have unique power requirements since some will have higher power ratings than others. A temporary power supply for a construction site should be durable to withstand the site conditions, portable to be used anywhere in the area and be able to provide the right amount of power for each tool.

Our Construction Site Power Supply Products

Trystar has premium power supply products for the construction industry. They last longer in the field and can be customized with your company’s colors and logos, so the equipment will look like your own. We have:


Temporary construction sites need a reliable and safe power distribution method for portable tools and lighting. Panels are the best construction site power supply option when you need to power multiple components simultaneously, as they allow you to control the power flow to each component and location at the job site. If you need to shut off power for one circuit, you can do so without affecting the power for the other circuits.

Trystar® Power Distribution Panel with I-LINE®* components

Some sites may need temporary power for construction beyond the capabilities of a power distribution board. Trystar® Power Distribution Panel with I-LINE®* components is portable and can support higher power flows for large equipment or several pieces of equipment in the circuit.

The Trystar® Power Distribution Pane lprovides massive amounts of power ranging from 400 to 3,000 amps. These units have a hard bus for durability and come with fork pockets and lifting hooks for portability around the job site.

*I-LINE® is a registered trademark of Schneider Electric USA, Inc.


Some construction sites may have a power supply line that differs from the machine’s voltage requirements. In this situation, a transformer makes the supply and the machine compatible for an easy power solution.

Our transformers are available in two styles — dolly style and cage style. With the dolly style, the transformer is on a dolly cart for easy transportability. The cage-style transformer sits in a cage with four wheels.

Portable ATS

In some situations, workers on a construction job may need to quickly and safely connect to a portable generator to maintain power availability. However, extension cords may be incompatible with this equipment and can cause unsafe back feed. A portable automatic transfer switch (ATS) is the easiest and safest way to transfer power from the main power source to a generator.

The temporary ATS serves when backup power is vital for operations to continue. It is rated for 200 to 480 volts and is housed in an aluminum noncorrosive enclosure.


Using temporary power for construction applications requires establishing a connection between the power source and equipment. Make the necessary connections for power with the portable industrial power cable. These single-conductor cables provide a reliable connection between the power source and the load while reducing the number of cables needed at the job site.
