JUICE ELECTRICAL SERVICES: IT’S LESS THAN TWO WEEKS OLD AND OUR CU INSTALLATION HAS BEEN MESSED ABOUT WITH BY SOMEONE PRETENDING TO BE AN ‘ELECTRICIAN’. ABSOLUTELY FUMING…!
It is extremely frustrating when you are conscientious and compliant with the requirements of BS 7671, show good workmanship and have pride in the quality of work only to find someone has tampered with your finished installation.
With this addition to a Distribution Board for a new circuit the culprit has installed an RCBO of a different manufacturer to the DB and the other devices. The requirements of BS 7671, and in particular Regulation 536.4.203, requires an assembly such as a Distribution Board to have devices that are declared as suitable.
Due to the type testing of devices in such an assembly the manufacturer would not be able to carry out product testing on devices that are not within its own product range.
Within the Distribution Board the circuit protective conductor (cpc) of the new circuit in way 2 has not been connected in corresponding terminals where the cpc is in way 11. Therefore, the classification code would be a potentially dangerous C2 incompatible overcurrent and RCD protective device.
