Electrical Equipment Simultaneous-Use Analyzer — Find the Heaviest Operating Group
Connected equipment is not necessarily all operating at the same time. Build realistic operating groups and compare their combined electrical demand.
Operating scenario inputs
Equipment and operating groups
Why connected load and simultaneous load differ
A property can contain many connected devices without all of them drawing their full rated power at the same moment. A kitchen, workshop, office or cooling scenario may therefore have a different maximum operating combination than the total connected list.
Use meaningful groups
Groups can represent a kitchen peak, workshop peak, cooling period, office work period or another operating condition. The quality of the result depends on the realism of those group definitions.
Why the largest group matters
The heaviest modeled group is a useful first-pass indicator of which operating condition creates the most demand.
Example
An oven at 3,000 W, microwave at 1,200 W and kettle at 2,200 W in one group total 6,400 W. At 230 V and 0.95 power factor, the simplified current estimate is approximately 29.3 A.
Limitations
This tool does not model time stamps, duty cycles, inrush, thermostat cycling, variable-speed equipment or detailed measured interval demand.
Frequently asked questions
Can the same device appear in different scenarios?
Yes. Add separate rows when the same equipment participates in different modeled operating conditions.
Does this calculate a real measured peak?
No. It calculates the groups you define.
Can I use VA?
The current version uses watts with the entered power-factor assumption for a transparent current estimate.
