What does a ring around wires mean in a wiring diagram?
A ring around wires in a wiring diagram most often represents a ring circuit in the wiring. A ring circuit is a wiring technique commonly seen in devices from the United Kingdom.
What type of circuit is one in which all loads are connected in a single loop-?
That is described as a circuit in series, as opposed to a circuit in parallel, in which there is more than one loop.
What size wire for a 230 volt circuit?
The size of the wire is set by the maximum current it has to carry. The voltage sets the size of the insulation. In the UK a 230 v (nominal) ring-circuit supplying a set of power sockets is rated at 30 amps and uses a ring of 2.5 sq-mm cable.
How many 13 amp sockets can a ring main contain?
BS 7671:2008, Requirements for Electrical Installations, specifies that any number of socket outlets can be added to a final ring circuit (ring main), but the ring main must not supply a floor area exceeding 100 square metres.
Home door bell is buzzing what is the cause?
A door bell works when the electrical circuit is complete. It doesn't work when there is no complete circuit. If it is just buzzing then there must be some electrical circuit, even though no-one is pressing the button.Somewhere there is a faulty connection, one that is making a slight contact, but insufficient to make the bell ring properly. Or maybe the 'ding/dong' unit is faulty.There are several things that could be done:# Rewire the whole thing. # Check the bell push, perhaps it is corroded or otherwise faulty. # Get an entirely new bell system. # Check all the wires, especially all connections. # Get someone who knows about electrical bells/circuits to check it for you. # If you rent the property and the bell is not yours but belongs to the landlord, maybe you could/should tell the landlord.
What does to bell or ring out mean?
It is electricians terminology to check the continuity of a circuit or a wire.

Why do you use a 30amp breaker on a ring circuit and a 20 amp on a radial circuit?
Answer for UK, Europe and countries running a 50 Hz supply service.A ring circuit has two routes to each outlet, a radial has only one.
What is a spur of a ring circuit?
this is a cable that is connected to a ring to supply electrical energy to one or more socket.
What will be usually described a branch from a ring final circuit?
spur
How long is the main ring?
If you are talking about an electrical ring main it can be as long as you want it as long as it returns back to the circuit breaker with the other end of the cable, which if you didn't return the 2nd end of the cable to the circuit breaker you would have a radial circuit.
What occurs when tip and ring of a telephone circuit are inversely installed?
I have no idea
What circuit has all the coponents in one loop?
It is a series circuit with all the components connected in series.
WHAT ARE THE RATING OF RING MAIN UNIT?
The normal rating of a UK ring circuit in a domestic system using 2.5 mm2 cable in a ring is 30 amps.
What type of circuit is one in which all loads are connected in a single loop-?
That is described as a circuit in series, as opposed to a circuit in parallel, in which there is more than one loop.
What is the size of electric cable needed for a ring main circuit in a house?
it is 5mm
A branch from a ring final circuit is usually described as a?
Spur
