Why measure a warehouse or plant instead of calculating it?
Industrial loads do not run on a schedule. Compressors cycle, forklift chargers stack up at shift change and dock equipment runs in bursts. Nameplate math adds all of that together as if it ran at once, which overstates the real peak. Recording the actual demand shows what happens in a normal week and on the worst day.
What do we measure?
- Main service and main distribution panel load
- Motor control centers and large equipment feeders
- Forklift and battery charging banks
- Compressor and pump starting current
- Voltage, power factor and phase balance at the main
What projects call for it?
- Adding racking, dock doors or a mezzanine
- Installing new production lines or automation
- Adding EV or forklift charging
- Responding to nuisance trips or voltage sags when equipment starts
- Preparing a utility service upgrade request with APS or SRP
What does the report give you?
You get the measured peak, when it happened, which areas drive it and how much margin is left on the main service and key panels. If the numbers show that the building is near its limit, the report recommends the smallest change that solves it, whether that is staggering loads, adding a panel or upgrading the service.
We assist engineers with load calculations and supply the field data.
How do we work around production?
Recording instruments clamp onto conductors and need only brief access to panels, so production keeps running. We schedule any shutdown for a time that suits your operation. Heat, dust and equipment hours are part of the walk-through. For the safe work practices we follow around live equipment, see NFPA 70E electrical safety. The overall service is on our Electrical Load Studies page.
