testing 2 radials in one mcb

[Guitarist]

that'd be a RFC then.

Exactly! I read it as an RFC split across 2 MCB's. Obviously you guys understand what the op is on about..

When testing a Consumer Unit with two radials feeding one socket on each circuit, wich results would you record on the condition report?

Emm no it says 2 radials

 

[shagbite]

that'd be a RFC then.

would it be a ring? or would you class it as a radial with 2 parallel cables?

 

[telectrix]

it's 1 MCB with 2 legs going out. each leg to a socket. so basically 2 radial branches. whet would be of concern is if the MCB was a 32A feeding 2 2.5mm legs, not configured as a RFC.

i know. my question was whether 2 cables feeding 1 socket would be classed as a ring or a radial. i'd go with radial.

 

[telectrix]

debateable.

Agreed 2 cables feeding one socket is technically a ring and should be treated as such or ditch a pair and its a radial

 

[telectrix]

u could only class it as a radial with parallel conductors if both cables are of the same length and follow the same route.

that's the picture i had in my head when i said radial.

Check both and record the higher of the two readings

This is what I thought. . .
why the two sockets are wired sepratly i dont know..

cheers for the replys!

Ah, so 2 separate sockets on 2 circuits... Makes sense now.

Couple of reasons maybe they were 2 separate circuits remember 30 years ago electric showers were not the norm all of a sudden they become affordable and they need a spare way in the basic 6 or 8 way 3036 CU. Another reason is an additional socket or outside security light where it is easier to wire from the CU . Wait until you get a socket spurred off a ring circuit in the CU

Which is , of course, perfectly acceptable.

What was the rating of the breaker ?

Tel's point -2 separate sockets on two cables from one OPD - only one circuit.


Why does RFC stand for RING Final Circuit and not RADIAL Final Circuit?
