Power, Generators & Lighting: guides and checklists

A generator that is too small trips under load, and one that is too large runs inefficiently at low load. These guides explain kVA and kW, how to size a set when motors and other loads draw extra current at start-up, the difference between prime and standby ratings, and when a silent canopy set is worth specifying. They also cover tower lights for night work and air compressors for tools. Before you contact suppliers, list every load you plan to connect, then read the sizing guide.
