With many farmers expected to undergo power outages over the next few days, farmers are urged to take care when it comes to using standby generators. The ESB has guidelines for such generators. Special rules apply to the installation of standby generators which your registered electrical contractor should be familiar with. It is vital that a proper changeover switch is installed at the main distribution board. A registered electrical contractor should always be used and it is important to always notify ESB networks of the presence of a standby generator.
