Answer this question Insert image from URL. Go to question listing. So extending a circuit to add an extra socket or two is a popular improvement when renovating.
New cabling can be surface run in plastic conduit to avoid damaging decorations and cutting chases into walls, but this needs to be done neatly. Depending on room size, a modern household requires about three or four DSSOs double switched socket outlets for each bedroom, five or six each for kitchens and living rooms and a couple for halls and landings.
The Building Regulations now require that power sockets must be positioned no lower than mm above the floor, and light switches no higher than mm from the floor. Installing a modern consumer unit fuse box is one of the simplest precautions to reduce the risk of electric shocks and fire. So if your old fuse box has ancient re-wireable fuses it should be replaced. Modern consumer units have MCBs miniature circuit breakers for each individual circuit.
It is recommended that systems are tested every 10 years or upon change of ownership. This is essentially an MOT for your home, and can be a lifesaver. This is followed by a series of tests carried out on the wiring as well as testing the insulation resistance to cables, and checking the circuits, consumer unit and RCDs.
Many homes have electrical systems of years of age which can still perform adequately with a spot of upgrading to bring them up to modern safety standards. Qualification for fitting fused spur? And could anyone recommend where to get this done and how much it costs? Installing security systems is not my full time occupation and only do year.

The problem is as always, if some thing goes wrong, because it has gone wrong, it points to you not having the knowledge, so you want some thing to show you do have the knowledge.
To show any HSE inspector your able to do the work safely you would also need to show you have access to test equipment, as to what test equipment not so sure. Before the Emma Shaw court case I was not really worried about qualifications, however in that case an electricians mate was asked to take readings which entailed plugging in a tester and writing down what it said when he pressed the button, he did not need to interpret the results, simply write them down, however it seems the meter showed OL or some other non numeric reading, so he asked in the canteen and wrote down what they suggested.
This resulted in his foreman being found guilty for using unskilled labour. The foreman could hardly argue the guy had the skill required because his actions showed he did not. Through out my working life there have been similar court cases for nearly every trade, and when you read them, one thinks there by grace of god go I. So to fit a FCU what do you need to know? Well we know it is not permitted to take a second supply from an unfused spur, so you need to identify the circuit you are tapping into, even when you know the load is so low, you still need to follow the rules, you need to test that the RCD supplying the new FCU will trip within the prescribed time, and current, and that the cables are within safe zones.
And be able to get all the information required to fill in the minor works certificate. In real terms issuing a minor works certificate is your get out of jail free card, it shows you tested and inspected as long as the readings put down actually match the actual readings, so if your certificate says the ELI at origin is 0.
So if a plasterer puts a nail through your cable, you can show it was OK when you left, nail must have gone in after you left.
