B.S. Number

[treehouse]

Could someone let me know the BS number for Multicore 90 degree thermosetting insulated cable, non armoured. Thank you​

I do not know when you would use that cable as it is rather more specialised than your average power cable.
However it would probably be made to IEC 60502.
It may be to BS7211 for LSF.
The only 90oC multicore cable you are likely to generally come across would be heat resistant flex (PVC/PVC) that would be specified in BS6500.

BS7211 would probably suit your needs, something like Draka Saffire OHLS, as this is rated in accordance with BS7671:2008+A1:2011 Table 4E2A.

What is this cable to be used for?
Signal or power?

Sorry if I appear thick but after 40 years on kilns and furnaces, it makes me a bit twitchy at times not knowing what you are doing.

Hi Tony,
I imagine I am like a good number of hard working contributors to this forum. I put myself in the "want to be as professional as I can be, but need more experience and the odd bit of help from those more knowledgeable category".

So I always spend a little time thinking about my thread because it seems there are a school of sharks, not sparks, out there waiting to snap at you with comments usually about competence. I could go on but I think I have made my point and having looked at the positive part of your reply I realise I could have added a bit more information. Therefore you, or anyone else, may be able to help further knowing the following.

I recently did some remedial work on an industrial unit and I was unsure how to remedy a CAT 2 observation made by the tester that a three phase circuit did not provide adequate overload protection. The Hager h125d circuit breaker fed a distribution boards less than a metre away via 35mm singles (Table 4D1A). Using Reference Method B the CCC isn't compatible with the circuit breaker and therefore I was seeking a remedy. Using 90 degree cable provides a solution and I was seeking more information about it so I could ensure I ordered the correct cable having not used it before.

I have considered changing the circuit breaker to 100 amp but the distribution board switch is 125 amp

Any thoughts ?

 

[cobrauk]

why would the distribution board switch rated at 125 amp make a difference its the cable feeding it that you are protecting with the 100amp circuit breaker m8 ?

 

[Engineer54]

To be honest with you, i can't see a problem with a 125A breaker protecting 35mm single core cables of around a metre in length. Up to you, leave as is, change breaker for a 100A, Sod about changing conductors!! I know what i'd be doing!! lol!!

A switch is a switch, absolutly no problem having a 125A switch switching a 100A protected circuit!!

I know that this is a silly question but have you clamped the dist board to see how much it draws with everything running?
