Staggered starting: power more with less generator

A simple operating habit that can let a smaller, cheaper generator run a bigger set of appliances.

The idea

Startup surges only happen at the instant a motor switches on, and only last a fraction of a second. If two large motors — say a well pump and an air conditioner — both try to start at the same moment, their surges stack, and you need a generator big enough for the combined spike.

But if you let one motor reach full running speed before starting the next, only one surge happens at a time. Your generator only ever has to survive the single largest surge, not the sum.

How to do it

• Start your largest motor load first, alone, and let it settle.
• Bring on remaining motor loads one at a time, a few seconds apart.
• Add resistive loads (lights, heaters, electronics) last — they have no surge.
• On standby systems with load management, this sequencing is automatic.

This is exactly why our calculator sizes for the single largest surge: it assumes sensible staggering rather than a simultaneous cold-start of everything. See the methodology →
