help regarding radial circuits

[demkap]

Hi all,

Today i found 2 radial circuits in a 32amp mcb breaker, would you give it a code c1 or c2 on a eic report?

Also what are the main dangers of having these together?

Cheers
Dem

Depends on the csa of the cables and the purpose of the circuits. Were they meant to be 2 radials or has it been an RFC at some time in the past?

 

[demkap]

they are wired in 2.5 and its a one bed flat. 2 radials in a 32amp breaker, when split one supplies kitchen and the other the rest of property. so id split them and put the in a 20amp breaker each, just wonder what code... and what dangers i could state?

What do you think the potential dangers are ?

What do you think the potential dangers are ?

None at all because 16 amps will flow down each 2.5 and the ccc for one is 27A so jobs a goodun.
Do I win a prize?

 

[demkap]

surely its a c2? its cross connected?

You win a white card with "Proper electric man" printed on it

 

[demkap]

you win a prize if you help me haha

What dangers could occur with the circuit in it's current state ?

GET IN! Finally, parity with a Electrical Trainee!
Oh erm, hang on...........

What testing did you do to prove it is two radials and not a broken rfc.

Bingo, first thing I would have looked for.

 

[demkap]

i always thought if a circuit was cross connected it was a c2

 

[BES]

If youve done no testing and have put two legs of a rfc into two seperate mcbs you could have two points of isolation.

You haven't proven anything mate, as I said in #2 and as has been said subsequently, has this always been 2 radials or is it a broken RFC?
You should at the very least have stated what the label on the front of the CU said was the intention of the circuit.

 

[demkap]

it wasnt even labelled as a whole on there, but on that one it said sockets. i tried to do end to end on them and got nothing.. then i separated them and did a r1+r2 individually and i got my readings to prove they are radials.. i just wanna know what code to put down as i know that they need to be 20amp breakers not 32amp

 

[trev]

Did you look at the neutral bar? Did the corresponding terminal have 2 cables in it?
Same question applies to the earth bar.
Did you do any testing? If so, what were your results?
If you're carrying out EICRs you can't allow knee jerk reactions to cloud your judgment. You inspect, you test, you report based on the regs.

So did you go to every point on these "radials" and take the r1r2

 

[demkap]

yes i did go to every point... i proved it was a radial. i just wanna know what code it is? if you dont wanna give me helpful advise then dont bother.

 

[trev]

Sometimes in order to give meaningful advice you have to ask questions mate.
Give it a C1 because it's obviously horrendously dangerous or don't give it a code at all because you "put it right"
I'm out.
