Hi there,

I am a fully qualified sparks before we get started.im installing a new circuit for camera supply's at a train station.its a 10 amp b crabtree the main switch is 100amp crabtree fed from a mains board on a 50amp type 2 single pole breaker.obviously I know how to carry out tests & sequence but were I'm struggling is finding the bs numbers for these breakers as they are not displayed & I know this could be simple stuff for guys who fill out certs regular, but I need some help in what to put down or where I can source info?
Any help highly appreciated cheer's

10A type B is a 60898 and the 50A type 2 is a 3871.

 

[ruaribedford]

Should have the BS codes printed on the circuit breakers

 

[Sharpend]

10A type B is a 69898 and the 50A type 2 is a 3871.

Should that be 60898?

 

[Sintra]

Yes should be. Big fingers and a small phone are to blame for the typo

nice one sintra! What about 100amp ms?? Going another station tonight so I will inspect the sides of the casing if I can disconnect surrounding breakers as some are in operation for track equipment.

Suppose I can google the numbers & get ka ratings.

thanks again guy's my expieriance on filling out is little

100a MS is 60947-3

60898 type B breakers are normally 6ka.....check the 3871,probably 6ka as well,normally marked as M6.

Cheers sintra,
I was going to record the sp&n board as supply characteristics with protective device being the main db 50 amp breaker.is this ok?
i can't source the exact origin as all these boards are together & the main db has a cert saying fed from isolator with no address or ref & could be to a sub station out of my duristiction.think I'm over thinking abit now.

 

[Deleted member 9648]

Supply characteristics are the origin of the installation,not the sub db.Regardless of practicalities you should be able to ascertain supply characterisics,if you REALLY cant you will have to note it as a limitation.

As it is a train station, make sure your breaker breaking capacity is above the PSSC/PEFC, it could be 10kA instead of the usual 6kA, don't get caught out.

Cheers wire puller.
spoke to a friend domestic installer he threw me as his supply's are obviously straight in.
it says to enquire I did try looking for on available certs & tables but there is no saying wether it be tns or cs.
What is the number for dno?? Is it easy to obtain this or should I lim it??

Billy - Please put that bloody breaker back in - I've been stuck for 30 min on a signal failure, and it's getting late! :smilewinkgrin:
