Sup. bonding, need to be in safe zones or not?

[Adam_151]

When its time to supp. bond the bathroom, not sure whether I'll be able to run it in the safe zones (might be able to sneak it into a corner one at a push), but I'm not actually sure its a requirement to run it in a safe zone, with protection, or 50mm deep.

Anyone got any knowledge one way or other?

Thanks


P.S. Anyone able to tell me the logic behind having to bond a lighting circuit thats going to supply selv fixtures in a bathroom just because there is class 2 pullcord in zone 3?...

P.P.S. Used 25mm PVC conduit in the end for the other shower, went to the orange and black shed and tested 10mm twin+e for size in a piece, plenty of room, slides in like *ahem* and well under 45% fill factor

P.P.P.S I've got a place on the 2330 at newark from sept

Yes run it either in a safe zone or outside the room through airing cupboard etc if you have one.

I think the logic behind it is if the pullcord was replaced with one with a metal body it needs to be bonded.

Good luck and well done, hope you enjoy it

Not actually sure that they answer my question, there is a paragraph that says they should be routed to avoid damage, but it doesn't actually say they should be in safe zones, so I guess it is implying that they need not be in safe zones, but I'm trying to find something more concrete than that

It makes reference to 413-02-27 , 547-03 and 413-02-28 , if someone could look these up and give me the rough outline of these please, because my book buying has only got as far as the OSG so far

Adam, sorry have just re-read your post and thought you needed to route the equipotential bonding rather than the supplementary bonding. To be honest with you I would work on the principle that they (both of them) do need to be routed in the "safe zones". I have read all of that chapter beyond the parts I scanned but it doesn't really add anything of any more value.

I once asked if extra low voltage cables where exempt from the zones and was told "no", and that's including phone cables.

I think it's one of those "best practice" things, unless anyone has a better answer.
