Hi,
I currently have a garage that has a very old Fuse box containing a 15Amp and a 5Amp fuse (not MCB). This fuse box is fed from the Main Consumer Unit box using a single 2.5mm2 cable. This cable is connected to a 15Amp MCB in the main consumer unit.
I want to upgrade this fuse box in the garage with a new mini consumer unit that contains MCB's as oppose to fuses. I have seen a new mini consumer unit on the internet which has the following specification (shipped from Israel).
2 way new consumer unit 1 x 40amp 30mA trip current RCCD, 1 x 6amp MCB's and 1 X16amp MCB.
Ideal for Garage, Caravan ETC.
IEC-898 STANDAD FOR THE MCB's
IEC1008-1 FOR THE RCCD
WHEATHER RESISTANCE GRADE - IP55
MCB's AND RCCB PASSED STRICTEST INSTITUTE OF STANDARDS TESTS
The Questions that I have are:
1. If I fit this new mini consumer unit in the garage should I upgrade the MCB in the main consumer unit from its existing 15Amp?
2. What rating MCB should I upgrade to in the main consumer unit?
3. What is the maximum amount of current I can draw on this single (radial) 2.5mm2 cable that runs from the main consumer unit to the garge conusmer unit?
4. I want to connect five 13Amp double plug sockets to the new 16Amp MCB in the new Garage mini consumer unit. Do i just run a single 2.5mm twin and earth to each socket in series (radial)? I.e. I wont have to run in a RING circuit for these sockets.
5. Do I have to run 1.5mm2 cable from the new 6Amp MCB in the new mini consumer unit to each of the lights in the grage. Can I just use my 2.5MM2 cable as I have plenty of that to hand.
Regards,
