Hi Guys Just a Quick question. sorry if this is a stupid question, and is a bit long winded. Going to do a consumer unit change soon and got in contact with the DNO to install a isolator for me. He arrived today and said that he could not do it as it is a porcealin fuse. It should be changed as they have a tendancy to break down. After a few calls to the Head Office he said that he could change it as the fuse looked in good condition, and so changed it. He then said that he will notify the relevent office to come out and change the service head, but this could take one month. But on the other hand as it is in good nic they may leave it as they would have to dig a hole in the street to disconnect the supply to the house in order to change the service head, and this would be costly and so had a kind of if it aint broke don't fix it attitude and that it would be ok to change the fuse board. My question is, as he did not know, what is the BS number for a porcealin fuse and what is the rated breaking capacity, as i did not have a tester to test Ze and prospective fault current and now worried about changing the board if it dont meet regs ie don't have correct breaking capacity to handle the fault current. also if no one is sure of bs number what can I put on the certificate as it don't have a bs number on the carrier or size of fuse. Also I would like to point out I want to use this for my assesment. Your input will be much appreciated.
Thanks
Thanks
