Exactly why are we carrying it out?
The simplest and most simple method of installing a supplementary socket or fused electric outlet to an existing ring circuit is always to put in a spur.
Precisely how to do it
1. Start by checking you have a 30amp junction box " this really is necessary for adding a new spur.
2. The next step is to find out where the nearest cable is to the site of the new outlet or fused outlet. This needs to be part of the existing ring circuit. You will probably need to lift the floorboards to find the cable.
3. The next thing is to fit the junction box. To accomplish this, 1st make a a small plinth to sit between the joists. This will work as a platform for the junction box.
4. Employ screws to secure the particular plinth towards the joists as well as the junction box onto the plinth.
5. Shut off your electricity supply.
6. Test a outlet on the ring main you intend to spur from to make sure that the electrical power is off.
7. Make use of wire strippers in order to remove the insulating material from the part of your cable that will fit into the junction box. You should now be able to observe three individual wires.
8. Remove the insulation from the live and neutral wires. The earth wire is already uncovered but has to be earth sleeved prior to connection
9. Undo your anchoring screws from your terminals within the junction box.
10. Put the exposed wires in the terminal holes, ensuring the earth wire is positioned in the middle hole.
11. Place the screws back into the terminal holes but keep these loose for the time being.
12. Now you can fit and join the mounting box and also face plate of the outlet or fused connection unit
13. Position the ends of the fresh cable in to the terminal holes on the junction box, ensuring you match up the colors up correctly.
14. Fasten your screws securely.
15. Position the cover of the junction box in place and screw down the lid.
16. Any loose cable should be fastened with cable clips
17. Turn the electricity back on and try out the socket or fused outlet using an electrical tester.
