I got this in an email, University Electrical Safety Regulations require that regular inspection and testing of specified electrical equipment has been carried out. Earthed equipment needs to have been tested and tagged in the last 6 months. Double insulated items needs to have been tested and tagged in the last 12 months. Please ensure all your equipment is tagged accordingly. Untagged electrical items will not be allowed to be used. If you are using equipment from your school, perhaps it is correctly tagged. Please check. I want to take me pc and so do 2 other mates .... so 6 power cords in total. Does this mean I need to get those little stickers on my power cord ? Were can I get this done ? How much does it cost ?
