Use Cases

The 50+ kW tier is for sites where a single generator needs to power multiple trailers or handle loads that exceed the 30-40 kW range.

🏗

Multi-Trailer Construction Campus

Three or more office trailers sharing a single generator with a distribution panel. GC office, owner's rep office, and subcontractor office all powered from one 50+ kW unit. Centralized fueling, single maintenance point.

🚿

Office + Restroom/Shower Trailers

Sites where both office trailers and restroom or shower trailers need electrical power from the same generator. Water heaters in shower trailers add significant draw that pushes beyond the 30-40 kW tier.

🏢

Large Office + Conference + Breakroom

Full-service trailer setup with a main office trailer, separate conference room trailer, and breakroom trailer. Combined HVAC across all three units plus full breakroom appliances requires 50+ kW capacity.

Need more than 70 kVA? We source generators up to 200 kW for large-scale projects. Pipeline construction, refinery turnarounds, military base camp support, and multi-building temporary office complexes often require 100-200 kW capacity. Call (844) 900-3190 for custom sizing and availability on larger units.

50+ kW Generator FAQ

We install a distribution panel (spider box) at the generator that splits the output to individual trailer feeds. Each trailer gets its own breaker-protected circuit. Cable runs are sized based on distance and load. We handle the entire setup — generator placement, distribution panel, cable routing, and breaker connections at each trailer.
Depends on the load. Two standard office trailers with HVAC and computers typically draw 15-20 kW combined — the 30-40 kW tier handles that. But if either trailer has a full breakroom, server room, or water heater, the combined draw can exceed 40 kW. When in doubt, tell us your trailer specs and we will calculate the load.
At 75% load, expect approximately 3.5-4.5 gallons per hour. Over a 10-hour workday, that is 35-45 gallons. The integrated 24-hour fuel tank ensures uninterrupted operation through a full work cycle. We set up scheduled fueling based on your actual consumption rate — typically every 1-2 days for full-load applications.
Yes, as long as the total load stays within the prime rating. The 56 kW prime rating gives you significant headroom. Start with two trailers at 20 kW combined, and you have capacity to add a third trailer or breakroom appliances later. If you outgrow the 50+ kW tier, we can swap to a larger unit (up to 200 kW) without changing your distribution panel or trailer connections.
