new codes c1 c2 c3

[Dayo]

Hi guys
has anyone got a table of where to use which code of the new regs c1 c2 c3
in particular what code covers cables less than 50mm in a wall, is it c2 potentially dangerous???
any help will be great

No code for this in particular as long as it's in a safe zone. You would more likely be coding for no RCD protection for cables concealed in walls ≤ 50mm

I don't see what safe zones have to do with it, it's a Code 3, check page 15 of the ESC Guide that Des linked to above.

From page 15: Absence of RCD protection for cables installed at a depth of less than 50mm from a surface of a wall.......

Which is exactly what I said:

There's nothing wrong with installing cables at < 50mm so long as they are in prescribed safe zones and they have additional protection by means of RCDs or mechanical protection is what I meant.

It was the mention of 'safe zone' that I queried, what did you mean?

I must have just edited my post as you were typing. See previous post.

Being a bit thick, when do the new codes come "in force"?

 

[Risteard]

1st January.

I think between now and January 1st you can use either, as is the case with the regs. After that you should be using the new ones.

thanks Des, hi Jud sorry i meant less than 50mm with no RCD protection,
thanks to all

hi Jud sorry i meant less than 50mm with no RCD protection

OK mate.

I misunderstood. I thought you were on about giving the cables themselves a code.

Cables concealed in walls, in safe zones without 30mA RCD protection would be a C3.

spin,
Surely that depends when they were installed?

 

[IQ Electrical]

No, the installation is compared with the current edition of BS7671 with installation date making no difference to the code attributed.

Would the date of installation make any difference to how safe it is?
