What Can a 50kVA Generator Run?

At 40kW continuous output, the 50kVA handles: a full construction site with cabin, tools, lighting, and small plant; multiple welding machines running simultaneously; a medium commercial kitchen or food processing unit; warehouse lighting, loading equipment, and cold storage; or agricultural equipment including milking parlours and grain dryers.
