Dear forum readers and Electricians Experts,
I am planning to wire up my garage (garage room + office room) myself but ultimately it will be certified by a qualified Electrican and with a marvellous certificate, oh joy another one.
I am planning to do the following in order as far I can:
1. Run a 10mm² for about 15m from my consum unit to the edge of my internal house
2. use an SWA armoured cable in a conduit which will be burried under 500mm (including tape at around 200mm depth indicating that electric cables are run underneath)
3. run adjacent to this cable (1 foot away) another conduit including CAT5e solid cable + perhaps cable for alarm system monitored 24H by ADT.
4. Use a consum unit (2xMCB for lighthing + 2xMCB for 2 ring main including in each room 3 to 4 socket-outlets [office room+garage] + 1MCB for interior electric heating [1kW] + 1 MCB for exterior electric heating [1kW])
5. 2 independant lighting circuit with 2.5mm2 cable
6. 2 independant wiring circuits [garage + room] with 2.5mm2
7. All socket-outlets in garage will be with built-in RCDs and be of type metal clad
8. 2 FCU SPUR to connect to the electric heathers
9. 1 FCU Spur to connect to an external socket outlet water proof (IP55+)
10. 2x 1way switches for the lighting
11. All circuit will be in conduit in the garage room.
12. All circuit will be wired standard in the office (4662 boxes with plaster around)
13. The total surface of the garage is 29m2 (build reg exemption) so in term of lenght of cable, it could be up to maximum for a loop to wire both room together for socket-outlet around 25-30m.
Therefore knowing all the above I have a few questions:
1. Is 10mm² sufficient? Bearing in mind that one top of the heating I may run washing machine
2. Would anyone know the type of cable to use for ADT
3. under the wiring regs, would CAT5e requires any additional precaution such as armoured? even if I use conduit?
4. How about the earthing? Does it need to be taken down on a stick next to my garage?
5. Is the number of MCB too much? Do I really need to have 2 lighing circuit for both rooms?
6. Again can I have one large wiring ring to cover both rooms of that same building?
7. for 5. and 6. if one is sufficient for circuit required what would be the rating to take for MCB and short-cirucit capabilities? (6kA, 10kA 10A-20A...)
Thank you for your asssitance all.
Feel free to ask further questions.
