Tasks
Each card is a reference, not a to-do list: it shows the energy present in that activity, then links to a calculator or trigger check. Open a card to see the direct controls to verify before work starts.

Temporary power setup
Trigger checksSetting up temporary power introduces energised distribution equipment into a changing construction environment.
Panel energisation
Trigger checksEnergising a panel introduces electrical energy that this tool does not calculate.
Live testing
Trigger checksLive testing deliberately applies electrical energy while people are working close to the equipment under test.
Switchgear commissioning
Trigger checksCommissioning switchgear moves equipment from a dead construction state to an energised operational state in stages.
Transformer delivery
Kinetic calculatorTransformer delivery combines a very heavy moving load with lifting, positioning and later connection to electrical systems.
UPS module installation
Gravity calculatorInstalling UPS modules involves heavy units, tight plant rooms and proximity to existing electrical systems.
Battery rack installation
Gravity calculatorInstalling battery racks involves heavy components, stored electrical energy and chemical exposure in confined plant space.
Battery connection
Trigger checksConnecting batteries works directly on terminals that cannot be de-energised, with arc and chemical exposure.
Cable pulling
Trigger checksCable pulling puts hands near rollers and pinch points while tension is applied to heavy cable runs.
Busbar installation
Gravity calculatorInstalling busbar sections involves heavy components at height and later connection to energised systems.
Cable termination and testing
Trigger checksTerminating and testing cables works at the boundary between dead construction wiring and systems that can be energised from elsewhere.
Earthing and grounding installation
Trigger checksInstalling earthing grids and bonding connects new conductors into systems that may already carry fault or induced current.
Lighting installation
Gravity calculatorInstalling luminaires and emergency lighting combines overhead work from steps or MEWPs with wiring that may become energised during commissioning.
BAS and BMS installation
Trigger checksInstalling controls cabling, sensors and panels routes low-voltage work through plant rooms and risers shared with energised power systems.
Mechanical and pressure · 3 tasks
Fan start-up
Trigger checksStarting fans introduces rotating energy and airflow into systems that people may still be working on.
Pump start-up
Trigger checksStarting pumps introduces rotating and pressure energy into pipework that may still be open or occupied by other trades.
Heat trace installation
Trigger checksInstalling heat trace fits electrical heating elements along pipework that later becomes both energised and hot.

Buried services exposure
Trigger checksExposing buried services risks striking electrical, gas, water or communications assets whose state is unknown.
Commissioning and testing · 3 tasks
Load bank testing
Trigger checksLoad bank testing applies full electrical load, producing high current and intense heat at the load bank.
Integrated systems testing
Trigger checksIntegrated testing runs multiple building systems together, so equipment can start, move or change state without local warning.
Sequential energisation
Trigger checksSequential energisation brings sections of the electrical system live in a planned order over days or weeks.
