A domestic electrical fuseboard needs to be changed when it is old or faulty. Changing a domestic electrical fuse board is a job that requires a suitably qualified electrician. The aim of this article is to supply non-electricians an understanding into what this process involves.
Firstly the power in the house needs to be checked to rule if it is working (i.e. Live), if it is live, then the power going to the main fuse needs to be isolated. The main fuse then needs to be removed.
Next the the power in the house needs to be checked to ensure it is dead (not live). Then cover of the fuseboard is removed and each terminal/cable (please note each cable will have a live, neutral, and Cpc) is disconnected, ensuring they are labeled so that they can be re-connected once the fusebaord is replaced. Then the old fuse board is unscrewed so that it can be removed from the the wall. The new fuse board is then fixed/screwed in where the old fuseboard was previously attached to the wall.
The terminals/cables are then reconnected back into the new fuse board. When reconnecting the fuse board, each cable is related in its corresponding number, i.e the first cable, live is related into the live terminal, the neutral and Cpc are related into the first corresponding neutral final and Cpc bar. This is then repeated for each cable.
Once all the cables have been reconnected then the cover of fuse board is replaced. The main fuse is then put back in and the power turned back on.
There are a range of hand and power tools required to unblemished this process, many of which can be obtained from any prominent high road Diy stores.
The main problem that could occur whilst changing a domestic electrical fuseboard is that the cable can be too short and therefore will need to be extended.
For a qualified electrician changing a fuseboard rates as about a 6 out of 10 in terms of difficulty and should take almost 3 to 4 hours to complete.
