01 / Planning step

List the loads and when they run

Provide the equipment list, available nameplate information and expected operating schedule. Explain which items may start together and which are critical to the work. Do not choose a generator from a rough total alone; ask a qualified supplier or electrical professional to assess the actual duty and connection requirements. Flag any load information you have not yet confirmed.

02 / Planning step

Describe the installation environment

Share the proposed location, access, distances to loads and the site's operating constraints. Discuss fuel arrangements, noise considerations and how routine service access will work. Ask what distribution equipment and associated components are included. Have the relevant electrical and site professionals determine installation, protection and connection requirements.

03 / Planning step

Agree the continuity plan

Explain the consequence of a power interruption and discuss the support arrangement appropriate to that dependency. Ask how fuel usage will be monitored and who responds to an alarm or shutdown. Coordinate delivery with the people receiving and commissioning the equipment. Record who can approve changes if the load list grows during the project.

04 / Planning step

Put it into practice

When a project adds another load midway through the hire, send the revised load information to the supplier and the qualified people responsible for the installation. Do not assume spare capacity from the original equipment label or the fact that the generator is running. Ask whether distribution, connection, fuel and servicing arrangements still match the revised use. Keep the approved change with the original brief. A current load schedule helps the next shift understand what the proposed arrangement was assessed to support.

Before you book

  • Load information collected
  • Operating schedule shared
  • Connections assessed by qualified people
  • Fuel responsibility agreed
  • Interruption response recorded

Use this checklist in your enquiry and record the provider’s answers beside each item.

Questions worth asking

Can I select a generator from a rough site description?

Provide load details, simultaneous use and starting patterns. The supplier and appropriately qualified personnel need to assess the proposed equipment and installation.
