bs numbers

[gpz900jim]

Hi, I wonder if anyone could give me the applicable BS and/ or BSEN numbers for fuses, breakers, rcd,s rcbo,s , main switches, etc that may be applicable to domestic wiring situations. Or maybe tell me if there is a table with descriptions anywhere.? Being a humble Domestic Installer, not long starting out, I do get a bit confused with which numbers to use when filling out an eic or mwc. Im sure this information would be very helpful to others in my situation. Thanks very much.

You can find these in Appendix 1 of BS7671, also, the tables for switching selection (53.2)

Appart from being in the brb as the guys have mentioned they are also printed on the accessory have a look

Sometimes if ypu don't have the BRB to hand it would be convenient just to have the BS numbers alongside an example photograph of the device - this would definitely help younger sparks get to grips with the BS numbers. Has anyone got something like this?

As above. But if you are a "humble domestic installer" as you put it just like me, then you should have a copy of BS7671:2008 The requirement for electrical installations in your possession. It would also be advisable to also have the On site guide, and the Electricians guide to the building regulations. It would also be preferable to be at least 16th edition qualified. If you have the qualification, and the books you should be able to find the info that you require with relative ease. With experience you will learn all these BS numbers of by heart like me, but until then you need to help yourself a bit, especially if you are just starting out.

as i have said Every product these days has the number printed on it MCB's RCBO's Switches sockets fuses cable if it hasnt got a number on it the it should be questioned as to its standard ,as howard has said you need to get a copy of the regs like him over the years you remember the numbers so look on the breaker or accessory or get the regs and look in there

Cheers, as brizospark said it would be useful if there was a picture and some wording alongside. Some stuff i find has no bs numbers on it so its easy to get into a bit of a knot deciding which is the applicable number. Rcds confuse me a bit, some of them have no bsen number on them, is an rcd which is used also as a main switch on some consumer units the same as an rcd that is sat along side a main switch. whic bs number is used for earlier and later type breakers? Its all very well you "seasoned veterans" saying go and look it up in the brb, isnt this site a place to go to ask questions. ? I know a lot of you blokes dont think a lot of part p guys, but this is a website for all of us, like it or not.

It is difficult when you're starting out but it's amazing how quickly you learn to look for the clues-if an MCB has type 1,2,3,4 or a short circuit capacity M3, M6 etc then it's a BS 3871.

The majority of main switch rcd devices are to BS 4293 (older) and BS 61008 for the newer variety.

Of course if you ever post a picture here with a 'what is this?" you'll get your answer probably within 5 minutes, this a great forum!

Des, Thanks very much for those, very helpful indeed.

 

[gpz900jim]

you too IQ!

Thanks chaps, im not trying to be lazy and asking for answers where i should be researching them myself, it really is hard to find the right number sometimes. looking in the brb can show 3,or 4 bs numbers for a particular item, and sometimes the descriptions can be a bit basic..What im very fearful of is putting the wrong numbers on my certificates for a whole year and being pulled up over it on my annual visit from the NIC.
