Level 3 C&G cable sizing calculations

[EFLImpudence]

Yes. So with MCB and method C 1.5mm² TandE will do but not allowed.

 

[plugwash]

OTOH with method 101 you would need 4mm².

 

[EFLImpudence]

That's not the point.

If you can post the whole question here, I shall query it with C&G themselves.

Did you manage to do that? Our lecturer hasn't managed to yet....

 

[securespark]

Have emailed but no answer yet ...

 

[securespark]

Still no answer.....I'm going to try and ring them.

 

[securespark]

Left a message the other day, no return call.

Believe it or not, I'm still on this! I have so far sent two emails, which have been unanswered, so I have sent a third to customersupport.

The phone system is like a telephonic rabbit warren....

Ha! Well thanks for persevering!

We've just been given our level 3 synoptic to do. Its the complete wiring plan for a bungalow, so there are at least 3 ring finals.

I've just gone with 4mm2 as the cables are under a lot of insulation so Ref Method 101. 2.5mm2 is only rated to 17A according to the OSG.

I think everyone else in the class is trying to work the full calculations, assuming 32A Ib...

At the moment, I'm working on the principle that they can't find anyone to answer my question!

 

[securespark]

Result, of sorts.

I think I'd better leave it to the OP, if they're still around, as I don't know all the relevant details.

Their response was as follows:

Dear Simon,

Thank you for contacting City & Guilds Customer Services.

We would need to know what exam and unit this question was on so that we can let our teams know.

Would you be able to provide any more information, such as the qualification and unit codes, or otherwise let the learner's training provider know so that they can also provide the learner details and further details to us, so that we can investigate this further.

Should you require any further assistance please do not hesitate to contact the Customer Services team on 01924 930800.

Blimey, that was quick!

I'll have a look and see if I can find the original source of the question.

 

[securespark]

Blimey, that was quick!

Yeah, must have been trying to contact the wrong departments...

 

[securespark]

Well, I hope this helps in one way or another.
