Load sequencer
Last updated: September 28, 2026 (CT). This is the tool wattage clones do not ship: you decide which circuits are allowed to exist in the same second.
A fridge + well + furnace + microwave naive sum looks like a 7,500 W purchase. If the microwave is in the “never overlap” lane, the well start never sees that 1,000 W, and the buy class often drops a step. That difference is the whole point of this page.
Add a row, set running / starting watts, then pick a lane. Always-on stays up. Wait starts after motors settle. Never-overlap is kitchen and space heat.
Why three phases beat one sum
Motors do not all lock-rotor at once unless you designed the house that way. The sequencer assumes one motor extra at a time among the always and wait lanes, and it assumes the never lane is dark during that kick. Then it checks two quieter phases: wait-lane running (AC after the well has started) and kitchen running (microwave with pumps already at running watts). You buy the worst phase plus headroom — not the fantasy that every nameplate is simultaneous.
Soft-start kits on a well or AC shrink the extra term. If you have one, lower that row’s starting watts toward ~1.4× running and re-run. Do not invent a soft-start you have not installed.
What this will not do
It will not tell you your well’s locked-rotor amps. Read the motor nameplate or the pump curve. It will not size a transfer switch — use the 30 A vs 50 A page after you know sequenced watts. Bonding a portable to the panel is still electrician work.
