Portacabin Site Office Power: Generator Sizing, Electrical Distribution & AC Loads

Powering Remote Construction Compound Cabins in the UAE

A well-functioning site compound requires reliable electrical power for executive offices, project management meeting rooms, IT server cabins, staff ablution blocks, and security gatehouses. Because these facilities are often established months before permanent grid substations are energized, temporary diesel power is indispensable. Explore our turnkey generator rental for portacabins solutions.

Calculating Portacabin Electrical Demand

The primary power consumer in any UAE portacabin is air conditioning. Due to summer heat, cabins require tropical-spec high-ambient T3 compressor units:

• 20ft Executive Office (6m x 2.4m): Typically fitted with one 2-Ton (24,000 BTU) tropical split AC (~2.8 kW running, ~6.5 kW starting) plus LED lighting and IT workstation power (~1.5 kW). Total required: 15–20 kVA generator capacity. See our 50 kVA silent generator for compact compound setups.
• 40ft Combined Office & Conference Cabin (12m x 3m): Fitted with two 2.5-Ton split ACs (~6.0 kW running), pantry refrigerator, water heater, and multi-user conference displays. Total required: 30–40 kVA generator capacity.
• Multi-Cabin Site Camp (5 to 10 Modular Units): Requires a centralized 100 kVA to 150 kVA silent generator paired with an IP66 outdoor weatherproof distribution board and rubberized Cam-Lock feeder cables.
