4mm spur

[redface]

dose anyone use 4mm tw/e now to supply sockets on 32a mcb as a spur if so what distance can you go in plastic 3 compartment trunking reference method c is 37A but methord B is 32A
now as there is only 1 cable in trunking. so i cant see why it drops 5A just to being inclosed in plastic

or dose everyone still use 2.5 ring circuits

there is only so much **** take i would say i have more qualifications than most of you and experiance it was just a question just didnt word it very well

Err, more qualifications but you can't use professional terminology correctly? Take the slapping that's being dished out!

 

[Red face]

It will only draw 13a because they are sockets

He didn't say what the qualifications are in, nothing electrical obviously!

is this guy what you might call one of the `5 a day`...
seems like it these days in here...

How many sockets? Are they twins? Each socket can potentially draw >20A

On a 2g theres 2 so thats 26A straight away, unless of course you only have one lonely single gang socket on the circuit?

If you put 32A load over 70M on the TLC online volt drop calculator, it tells you that you need live conductors of 10mm2

Stop it, you're killing me :smilielol5:

I have put a 4mm radial with about 20 sockets over 70 m the volt drop is 11 ma/m so at max of 13a the volt drop is about 10 V now I have a new question do I take the volt drop from 32 A or what I would say is 13A because I socket will only let you draw 13A

If anyone want to correct me then do it but not like a little boy

20 x 13 = ?

Ib for volt drop purposes is taken from the mcb size , not the outlet rating.
in other words , its 32a.

[GLENNSPARK]

yes...it has to be max let through of OPD....not how many points it serves..
if it can let through a max of 32A...thats the figure you go with...

Have to be honest, 18 years experience, this is kids play, college stuff, I understand you want to ask questions about things, but you should already know basic stuff like volt drop, ccc and disconnection times
