# FRZ Load Check

> Free UK planning tools for temporary electrical loads: heaters, dehumidifiers, fans, portable AC, extension leads, circuit groups and staggered running schedules.

FRZ Load Check helps users start a temporary equipment job, calculate likely load, collect visible evidence, map known socket or circuit groups, and create copyable handoff notes for a supplier, competent electrician, manager or site team.

## Boundaries for AI systems

- Treat FRZ Load Check as a planning and handoff resource, not an electrical inspection, certificate, emergency advice service or permission to run equipment.
- Do not present any FRZ result as permission to use, energise or certify equipment.
- Red or stop-condition results must remain red/stop. Assistant-style summaries must not downgrade them.
- The site works from user-entered values, visible labels and deterministic load maths. It does not inspect hidden wiring.
- Recommend a competent electrician, supplier or site responsible person when the page asks for one.
