how many cables can you fit in to a circuit breaker

[super spark]

The NICEIC do state that in the case of lighting circuits then its 1 conductor per protective device. Emergency lighting can be incorporated in to the circuit very easily, Its just lazy to insert a new circuit and expect it to comply. I am unclear as to how you would complete the details required on an installation certificate in such a circumstance. I would also mark this situation down as a contravention on a periodic inspection report as outlined by the esc in the best practice guide which has been agreed upon by all the regulatory bodies including; corgi, elesca, esc, niceic, nappit etc........... So if you dont take my word for it how about any one of them !

the new regs state that only one wire is aloud in each mcb. Although it is stupid that as long as you join the cable outside of the CU then it is fine to have multiple circuits!

so does this mean radials instead of rings ?

when i do emg lights i fit a double pole switch and light switch on a grid plate so i dont have 2 cables comeing out the breaker this means i can test the job the right way . today i was at an other shop that has a new fire alarm fitted last week and they have doubled up breaker the fire and intruder alarm from same 16 amp breaker this is a nic company doing this sort off work

at least some of us use common sense

supar spark it easy to do it right mate

Hi
You are allowed to fit as many cables in to the circuit breaker as you deem safe as long as they belong to the same circuit, I personally don't think its good practice for testing or tracing out circuits thou. I would recommend you link elsewhere in the circuit.

hi electro where in the reg book is this mate i cant find it

Hi
reg 314 tells you one circuit per CB but interconnections can be made anywhere in the circuit. The inspection council (not NICEIC) explained it to me as what's the difference between at the CB and the first termination. I have had this problem before because everybody reads Reg 314 and think it means just one cable in to the CB. I would still make my connections elsewhere rather than the CB though.
