Sequential energisation: energy sources and direct controls

Sequential energisation brings sections of the electrical system live in a planned order over days or weeks.

High-energy check

Treat every newly energised section as high energy. Yesterday-dead equipment being live today is the main exposure.

This task's main energy sources are not calculated by this tool. Use the trigger checks below and competent-person verification.

Trigger checks

Electrical
Current, voltage, energisation, arc flash or stored electrical energy.

Direct controls to verify

Ticks stay on this screen only. Nothing is saved or sent.

The energisation scope for the day is confirmed and communicated to all trades.
Newly live sections are locked and labelled before the change.
A single named authority approves each energisation step.
Isolation points for remaining dead sections are proven after the change.
Drawings and labelling are updated the same day.
Stop if any section status is unclear or labelling is missing.

For your SPA or pre-start

State which sections go live today, how the change is communicated to every trade, how live sections are secured and who holds the energisation authority.
