    Ring Final Circuit - spurs only

    I refer you to post 19. "There are plenty of ring final circuits out there which do not incorporate socket outlets." Getting somewhere.

    Ring Final Circuit - spurs only

    The point is a ring without sockets, either with for e.g., having only jboxes or appliances hard wired on the ring. Why the jbooxes are there or why the appliance are hard wired in is not the point. It is a regs point.

    Thx. So OK to have a ring with no sockets on it.

    Ring Final Circuit - spurs only

    The point is a ring without sockets. It can have: 1. just jboxes or; 2. hard wired in appliances on the ring. It is not difficult to grasp.

    Ring Final Circuit - spurs only

    Please try and focus on the point i was making.

    Ring Final Circuit - spurs only

    If this situation arose is it legal? A ring with only jboxes is the point. Or the actual ring cable with no sockets on it.

    Ring Final Circuit - spurs only

    Just a thought on this. A ring with jboxes only. The jboxes supply only one socket via a cable approx 2 to 3 metres long. Big saving on cable.

    Ring Final Circuit - spurs only

    A dedicated ring for only heavy appliances, hard wired in comes to mind. Sockets on a separate ring.

    Ring Final Circuit - spurs only

    So, a ring can be just a ring of cable - in effect a busbar. Then on this cable j-boxes with spurs off that.

    Ring Final Circuit - spurs only

    I read that it is against the regs that a ring final circuit cannot be just a ring with with spurs off it. In short, a ring must have sockets on it which double up as junctions. I find that hard to believe.

    Why does the UK use rings for sockets?

    For information. People read the threads.

    Why does the UK use rings for sockets?

    A final ring has many advantages. It is interesting on how it came about. The ultimate socket design is to have a radial to each socket outlet on its own fuse at the Consumer Unit - the optimum solution of course. One fuse at the Consumer Unit for each socket. This means you will need a very...

    France wiring question

    Mike, are DP RCBOs available in France in the likes of Leroy Merlin? I was considering changing the innards of a 50 year old plastic semi-in-the-wall Legrand main panel that has fuses - in an apartment. It is easy to fit some DIN rail where the fuses are, but two RCDs would make matters...

    Cheap AFDD implementation in flats.

    You are guessing that money would not be an issue. Money being an issue or not, the aim is an AFDD protected installation to regs at "minimal" cost. If you can suggest a cheaper method please do.

    Cheap AFDD implementation in flats.

    I see no complexity in the wiring. 1. Heavy appliance sockets cable back to CU. 2. General sockets cable back to CU. 3. Lighting cable back to CU. 4. Cooker cable back to CU.

    Cheap AFDD implementation in flats.

    Adding another AFDD at £150, is not an option, as costs spiral. The exercise is to get full AFDD protection in a flat meeting regs at minimal cost.

    Cheap AFDD implementation in flats.

    Say a block of 60 flats in a 6 floor old block renovation like seen in London mansion blocks. All flats have gas heating. Costs are then dramatically cut for the electrical installations giving full protection. AFDDs may drop dramatically in price, but far from that yet. The drop in the price...

    Cheap AFDD implementation in flats.

    The AFDD can serve a radial with sub radials off it. Within bounds of AFDD. The sub radials just have fuses on them. Nothing wrong with that. DIN fuse carriers in the CU is for convenience. A professional working in the CU would not bodge the job.

    Cheap AFDD implementation in flats.

    One RFC can be done for sure. 4mm cable can be run to heavy current appliances in kitchen, to ensure a 2.5mm cable does not fry. What I outlined in post 1 can be one 40A AFDD on a radial with two or three sub radials off it. There happens to be a fuse to the sub radials. The DIN fuse holders...
