Load Banks

Units used to test and verify generator performance under controlled electrical load. Critical for commissioning, maintenance, and ensuring standby generators operate at peak reliability before they’re needed in real-world conditions.

Transformers

Step-up or step-down transformers for voltage conversion, e.g. 480V to 208V, to match site requirements. Necessary for projects with mixed voltage needs or sensitive equipment.

Transfer Switches

Automatic or manual switches that safely transfer load between utility and generator power. Critical for seamless backup during outages and NFPA compliance in healthcare and critical facilities.

Spider Boxes

Compact power distribution units that split a single generator feed into multiple circuits. Ideal for events, construction sites, and temporary setups where multiple tools or systems need power safely.

Power Cables (Type W)

Heavy-duty cam-lock cables designed for high-current connections between generators, transfer switches, and distribution panels. Available in 50 foot lengths.

Cable Ramps

Heavy-duty cable protection ramps that shield power cables from vehicle and foot traffic. Prevents damage to electrical lines while reducing trip hazards, making them essential for construction sites, events, and temporary power setups.

Heaters

Industrial-grade portable heaters designed to provide safe, reliable warmth for job sites, event spaces, and temporary structures. Ideal for maintaining comfortable working conditions or protecting temperature-sensitive equipment during cold weather.

Quad Stringers

Multi-outlet extension assemblies that distribute power from a main feed to multiple devices or panels. Perfect for job sites needing multiple connection points without overloading circuits.

Fuel Tanks

Extended-run diesel tanks that allow generators to operate continuously. Includes spill containment options for environmental safety and compliance.

Distribution Equipment

I-Line Panels and breakers that manage power flow from the generator to multiple circuits or loads. Ensures safe, balanced distribution for complex setups like construction or events.

Spill Containment (for purchase only)

Protective barriers and trays placed under fuel tanks and generators to prevent leaks from contaminating the site. Essential for environmental compliance and safety.
