Can anyone tell me if there is anything written in any of the Regulations about vermin control for Electrical enclosures? I have read through the Prevention of damage by pests act 1949 and cant find anything relevant (correct me if I'm wrong). We were recently asked by a customer to find a solution for a vermin control issue and we would like to incorporate something into our design rules. I did find a brief paragraph in the BS6423 1983 Maintenance of Electrical Switchgear upto 1kV but still nothing that truly helped!
