As a U.S. resident, it was enlightening to find out why you use ring circuits. In the U.S. we do not have ring circuits. And to you that think we only have 120VAC in our homes, we do have 240VAC, but split among 2 legs. The power is delivered by two 120VAC hot wires and a neutral wire. To get the 240VAC, the appliance needs to be connected to both hot wires and a safety ground.

Non UK sparky here. I'm getting into awful rows with UK electricians here on the internet whenever they loudly sing the praise of the UK Electrical System. Since the whole world speaks English, many a non professional learns about the many safeties built into the UK plug and wants the same thing. Some of these plug safeties (the fuse and strict adherence to polarity among others) are there to counteract (among others) the risks inherent to a ring circuit, like a cable break. Sketching the historical context is also very valuable. This video is going to be a mighty good explainer to avoid all these awful rows therefore my thanks ;-)

Many clearly do not understand what a final ring circuit is. The ultimate system is to have a radial circuit to _each socket outlet_ on its own fuse at the main panel - the optimum solution of course. This means you will need a _very large_ expensive main panel and lots of fuses/MCBs (one for each socket) in the main panel. Impractical of course. 🎊🎈 *BINGO* 🎊🎈 *A ring gives this by distributing the main panel around the house via a ring cable,* distributing the fuses from the main panel around the building to each socket. *The ring is a busbar.* This saves the vast expense of a plethora of radial cables back to the main panel and also a plethora of expensive fuses/MCB's/RCBO/AFDDs at a _very large_ expensive main panel and expensive labour to install. *a)* A ring uses less cable and gives a longer route *b)* No limit to sockets on the ring, but total is limited to typically 32A. *c)* A ring uses less copper for a given load/area. *d)* Rings rarely have voltage drop as it is fed from both ends. *e)* Rings have lower impedance, less volt drop is less waste! They are more efficient. *f)* No single point of failure for the protective earth. *g)* If you are covering all rooms in one floor then a ring can do it. *h)* An appliance and its flexible cable may have a fuse sized to its rating inside its plug. *1.* Ring final 2.5mm cable, 32A B-curve MCB, length *106m* on TN-C-S. *2.* Ring final 4mm cable, 32A B-curve MCB, length *171m.* *3.* Radial final 2.5mm cable, 25A B-curve MCB, length *33m.* *4.* Radial final circuit, 4mm cable, 32A B-curve MCB, length *43m.* If a ring is in 4mm cable protected by a 32A MCB/RCBO, then no problems if the cable is broken - which is a very rare thing. The ring can be partially 4mm to heavy current appliance sockets one one leg, and 2.5mm for the rest The ring final circuit is safe, simple, and highly effective after 80 years of use. The introduction of MCBs/RCBOs/RCDs/AFDDs, and screwless Wagos on the ring taking the load, has made the ring even safer.

@9mmfederalrimmed2357 ай бұрын
How interesting. I understood it. So the english ring circuit is dangerous over time and the cables could cause fire if the ring is interrupted. That is why the radial circuit is inherently safer but uses more copper. The rest of the world uses thus the radial approach.

@@learnelectrics4402 Yes here from Southamerica. Actually we use here only the radial approach as far as I know. Most houses have several magnetic breakers for every cable one for example one cable and breaker for the air condition independently of each room, one for the light bulbs of each room, one breaker for the electrical shower apart, each bathroom each shower apart, one of the sockets of each room apart and so on. If there is a problem the breaker snaps down and you know you have to call the electrician. Additionally there is an main magnetic switch for each of the 3 phase power line and on top of that an general magnetic breaker. Then most have an Fi human protection breaker as we call it. Over here this country adapted together with Brazil and Southafrica the new swiss modified plug system recently developed by the international electric society. It is an variant of the swiss plugs but with the british shutter system. These plugs look like an rhombus but do not have an built in fuse like the british do. Supposedly these support Schuko type 16A currents or even more as I heard. Have not seen any implemented yet. Till date we use here the Euro plug combined with the US plug styles. We use them both. These take the german Konturenstecker (washing machines and such) as well but often the house cables are a bit to thin for such 10A drawings so we have to watch any plastic meltings on the sockets. The US and Euro plug system works as well and really there is no huge need to switch.

Great explanation. I understand the reasons why ring circuits came about, but don't understand why they still seem to be commonly used today when, as you say, we have CU's with so many ways. Surely the risks posed by an undetected broken ring doesn't out weight the potential slight uplift in cost installing radials? That said, I'm not an electrician, so prepared to get shot down on this one. 😳
@learnelectrics44023 жыл бұрын
Personal choice at the end of the day Gary. Some people, including electricians, would you believe, still think that a socket circuit MUST be a 32amp ring. Why? Do you need 32 amps in the bedroom where there might be a TV, a computer and a bedside lamp, 5 amps max. Thanks for the comments, you are spot on, nothing to shoot you down about. And I do agree about the risks of a broken ring on a heavily loaded circuit. Thanks for watching. Dave.

@learnelectrics4402 Жыл бұрын
There is no proper answer to either question. It depends what the customer wants. 20A and 2 sockets might be ok for a bedroom, but it won't work for a kitchen. You can have 32A or 20A for a ring. 32A kitchen and 20A bedrooms. The 20A breaker gives you a bigger permitted Zs which is better for longer runs.

Continuity test at the CU is the only sure fire way. You can take a guess by breaker size and cable csa but testing is best. Thanks for watching. Dave.

the electricity is still using twice the copper on a ring circuit. It's just like you doubled up the leads is all. the electricity is not flowing any differently un less you get a disconnection in one of the sockets. It is just like you ran tWo 2.5 mm cables radially. Electricity doesn't see circles and only sees conductors and actually runs around the conductor wire helically clockwise due to the right-hand rule. Radial circuits are a bad idea because if any one of those connections is broken you will have too much amps on one wire basically. A lot more room for error. I like how the UK uses fuses on every PLUG. We use them for fans but that's the only appliance with its own fuse in the plug.

I think you mean ring circuits are more likely to overload the wire if there is a break....

Hi Dave Why do we have a 32amp ring. Why was it settled on this rating. Is it to do with the 1.45 I2 value etc
@learnelectrics44022 жыл бұрын
Nothing to do with maths. It was just a value of current that a whole house might typically use at the sockets many years ago when there were few electrical goods. Once the fuse size became established, it stuck. Now we have several 32A circuits in a house.

Suppose you have a main ring. And you spur from one of the sockets. Question: Can you create a smaller ring circuit from that spur ?
@learnelectrics44022 жыл бұрын
Good question and the answer depends on how you do it. One way is yes, the other a no. Take a look at these two videos and decide what it is you want to do.

Good vid but its not common for cables to be cut in normal conditions. So which is better. I prefer ringmain. I was hoping your vid would clear this up for me. But it doesn't.

Colin, there is no better way; it is all down to personal choice. There is no right or wrong with ring or radial. It is left to each electrician to decide and as long as it is safe and functional I can't see that one is any better. I can't be any more helpful than that. Dave.
