In plain language
When a proposal mentions Critical loads panel, identify the exact equipment, configuration, and included work instead of assuming the label describes the whole system.
What it is not
It is not a promise that every connected load can operate simultaneously or indefinitely.
Decision context
Why it matters
Circuit selection, load power and energy, transfer arrangement, code, future loads, user priorities, and battery or generator capability must be designed together.
