Connecting a Standby Generator (not operating in parallel)

A standby generator is used for emergency power generation in the rare event of the loss of electricity supply. For instance, such a situation could occur as the result of:

  • A planned electricity interruption by ESB Networks
  • A fault on the electricity network
  • A storm or third party damage to the electricity network

For safety reasons please inform the Customer Services Supervisor in your local ESB Networks office if a standby generator is to be installed at your address. (Your registered electrical contractor will have the contact details.)

If you are planning to install a standby generator, it is important that it is installed by a registered electrical contractor.

The generator must always be connected through a change over switch in order to ensure that parallel operation with the electricity network is not possible. The generator and it's associated wiring must also be installed to comply with all relevant Electro Technical Council of Ireland rules.

Safety First

Only qualified personnel should install a standby generator. This is because incorrect installation could prove fatal.

Most importantly, a standby generator (even a very small one) should never be connected on a temporary basis to the electrical circuits in your premises or to your metering point. To do so could endanger you, your neighbours and ESB Networks' staff.
