In our basement we have a metal double socket which I believe is wired directly into the Consumer Unit. We currently have these plugged in.
- fridge (750W, 4A max)
- washing machine (2400W, 11A max)
All works fine.
I now want to add 3 extra sockets:
- Tumble Dryer (2600W, 12A max)
- double socket above worktop for...
- hoover, iron, etc
So increasing from two sockets to 5.
Qu 1: What is the best way to extend the existing double socket to add 3 extra sockets.
- I am in the UK, so 230V AC.
- Running the washer machine, tumble dryer and iron all at once, would draw about 10A each, so hit the 30A limit, but that's probably likely all will draw that much at exactly the same time.
- I assume the ring main has a breaker of 30A (which I need to double check).
- I can't use a spur from existing socket as this will pull too much current.
- It sounds better to continue this as a ring main rather than a radial circuit.
- Using a double socket for washer/dryer isn't great as they don't deal well with 20A+.
- Each major applicance would plug into a switchless single 13A socket.
- Each switchless socket would then connect into a 13A switch (above the worktop).
Qu 2: Can I just connect the 3 x 13A switches in parallel from the existing wires coming from the consumer unit?
Qu 3: I presume if I want a normal double plug/switch (above the worktop), I can add this in parallel as well.
Qu 4: Presume makes these changes will need me to get an electrician to certify it (even if I do the work myself)
