Amen to that brother!I think that rings and radials can and will coexist for a long time to come

I'm sure if radials from different house holds meet up and sparks flyWhy I even know a couple of radials, we're not close friends but I don't have any issue with their lifestyle
I think your right zap. They will go their seperate ways and it's only a question of time before one of them says " shoulda put a ring on it "I'm sure if radials from different house holds meet up and sparks fly
.. It wont be as spectacular as RFCs !
Only just saw this post while searching for something else. But yes hypothetically you (and us) could lose the fused plug tops if we reduced the ring circuit to a 20 rather than 32 amp. Ironically in ROI we still use fused plug tops on 20 amp radials because rings are still allowed and an installation may be altered to incorporate a ring. On the continent I have never seen a fused plug top in use. All their appliances, come with unfused plug tops. If fused plug tops should disappear, they won't be missed.Just a few things i'm throwing out - Rings seem like they would be safer on 20A MCB but I guess there's very few accidents for this to be questioned by the powers that be.
If rings disappeared hypothetically would we loose the fused plug?
I'd be interested in the layout of some European Radials rules and Regs - Spider circuits and what's allowed.
This Hong Kong Code of Practice suggests Rings
I think a few other Asian countrys use them and wonder if they use Fused Plugs
So long as all cables and accessories are rated for the fault.But yes hypothetically you (and us) could lose the fused plug tops if we reduced the ring circuit to a 20 rather than 32 amp.
I think the waters get muddied sometimes regarding protection for appliances etc. Strictly speaking its the manufactures responsibility to ensure his product is adequately protected and is suitable to be plugged into the domestic installation its designed for. Electricians strictly speaking should only be concerned with protecting the wiring they are installing. Though we naturally are alert to any household accessories that we may feel merit a "closer look" Funnily enough the only times I have had concerns about cables been sufficiently rated for fault current and let -through has been in the control circuitry of appliances. In some traditional stand alone cookers for instance you could see 1.5mm and less supplying the rings and smaller again going to the controls. All backed up by a 32 amp mcb. Have never seen any of the cabling damaged by short-circuit though.So long as all cables and accessories are rated for the fault.
To me having, say, a 3A HRC fuse on a smaller bit of electronics makes a whole lot more sense than trying to ensure everything (cable, connectors, switches, PCB tracks, etc) are able to safely clear a 20A MCB's let-through.
Lets face it, the majority of stuff is not in need of 10A supply, not even 1A in many case. Though the rest of the world either accepts higher fire risk or pays more for uprated conductors.
Indeed, but we are musing about the hypothetical case of different mains plugs/sockets being adopted in the a country that has the 13A fused ones already.Electricians strictly speaking should only be concerned with protecting the wiring they are installing.
Aside from the ascetics of other countries plugs (valid point by the way) I see little point in inserting fuses in circuits if they don't have a specific role. Having to pull a washing machine out from under a worktop or having to take apart the "chimney" in an extractor hood in order to replace a fuse in a plugtop are two instances I could mention where I would prefer the European method of an unfused plugtop on a 16 amp mcb.Even if ring circuits were ripped out and replaced with radials, I can't think of a single reason that could be put forward as grounds for dispensing with fused plugs..
The only complaint I've ever heard is that they aren't particularly pleasing to the eye, but I don't remember ever looking at a plug from any another country and thinking it was a thing of beauty.

I completely agree about the upheaval that may be caused as outlined by "Pc1966". And holding on to the fused plugtop is certainly no disadvantage. Considering that all fixed appliances now have isolators anyway (if inaccessible which they usually are) it would be very easy to arrange a SFU above the worktop and have literally an "unfused" plug top on the appliance itself. Problem solved.Fair point, but how often do appliance fuses need to be replaced? Obviously an electrician would see more instances of this than an average householder, but they do receive remuneration for that service. Washing machines are indeed a pain to move - expecially where vinyl flooring is concerned, but extractor outlets could often be sited above wall units and in many instances this inconvenience stems more from poor planning during installation. In my own home I've replaced a handful of fuses over decades, but these were instances where I was making exploratory checks on a failed appliance - on none of those occasions had the fuse blown.
I don't think that electricians having to replace an occasional fuse is reason enough to undergo the huge upheaval that would be inolved in ridding these islands of fused plugs. I'd also question whether removing the relatively minor inconvenience of an occasional blown would come close to compensating for the potential issues caused by such a move?
Or simpler still, just have the 13A sockets above the appliance?I completely agree about the upheaval that may be caused as outlined by "Pc1966".

Agreed. It's a very practical solution to have it about the appliance. But in a modern kitchen? Homeowners won't accept itOr simpler still, just have the 13A sockets above the appliance?
As above, when something blows a 13A fuse it is almost always a hard fault that is going to need the unit removed from its hiding hole for repair or replacement (OK, for 3A fuses and bedside lights then occasionally they would go with a filament lamp's bulb). If it were RCD sockets prone to random trips it would be very different, but I think I have only once had a fuse blow that upon replacing no other fault was found.
But I did not look inside for any remnants of an evaporated spider...
Ah, the triumph of appearance over function! Could go in adjacent cupboards of course.Agreed. It's a very practical solution to have it about the appliance. But in a modern kitchen? Homeowners won't accept it
Yes. That is always my preferred solution. Issue there (in my experience at least) is that modern cupboards are now coming fitted out with all sorts of racking and specialised drawers meaning the socket is no longer accessible like we used to have with the old traditional cupboards. And inspectors are increasingly picky about what is and is, nt accessible. So to "avoid grey hairs" tend to stick to typeAh, the triumph of appearance over function! Could go in adjacent cupboards of course.
