A load study shouldn’t take six weeks and a consultant.
Traditional firms sell hours: site walks, spreadsheets, weeks of waiting. Wattif rebuilds your electrical system as a verified model and runs the calculation on your own measured demand. Every report is quoted before any work starts, and most come back in 3 days.
One report, from two kinds of evidence.
From your utility records
Your real 12-month peak, with the margin your code requires. Routinely recovers capacity the calculation cannot see.
Ready in 3 days →From 30 days on the panel
The only measured path for feeder and sub-panel additions, or when no usable records exist.
Ready in about 5 weeks →Three steps. 30 days. One answer.
- 01, Day 0
Sensors go on the panel
A contractor mounts CT clamps on your mains and feeders, typically under an hour on site. No shutdown, no rewiring, no disruption to the facility.
- 02, Day 1 to 30
30 days of evidence
We monitor exactly what your study needs: the mains, one feeder, or several panels across the site. Real kilowatt data at 1 to 15 minute resolution, matched to the question.
- 03, Day 30
The determination
The recorded peak, with the margin your local code requires, is set against the rating of the service or the feeder the load is going on. A licensed engineer reviews and signs it under their own licence. You get the answer in plain language, with the numbers behind it.
How else would you get this answer?
There are three ways to get a load study today. Two of them cost more and take longer.
Engineering consultant
Hourly billing, a site walk to redraw what your documents already show, and the study lands in the queue behind bigger jobs.
Do it in-house
Spreadsheet math from the panel schedule. Nobody has checked it, no licensed engineer has signed it, and the liability stays with you.
