Hello, another post about the 17th edition regulations, I don't want any discussions going on in here please ( I beg ya ). Just a list of the new regulations/changes etc, see how long it'll go before someone starts chatting on it. I'll start it off


-------------------------------------------------------------------------------------------------------

RCD's
- Required for s/o of up to 20amp or less for the use by ordinary persons (unless labelled for a specific purpose such as a "freezer only"

- Required for s/o up to 32amp feeding equipment outdoors

- Buried cables in safe zones LESS than 50mm from the surface UNLESS earthed metallic protection Provided

Special locations;

Zone 3 no longer defined,

Each circuit in special location must have 30mA RCD protection,

Supplementary bonding no longer required provided main bonding is in accordance with chapter 41,

Socket outlets now allowed in locations containing bath/shower 3m horizontally beyond boundary of zone 1.

Everything to know about the 17th Regulations is in the red book but i can't find the info I need. The red book is the hardest book to find stuff in...

Supplementary bonding not required if all electrical acessories are protected by 30ma rcd...is this true?

Shakey

presumably in a bathroom

30mA RCD
AND meet their disconnection times
AND 1667ohms or less for any extarneous paths back to MET
AND main protective bonding is in place

Luke,

why are you so against discussions on here? If someone posts something that is their 'interpretation' or somebody else wants explaining surely we should do so?

I cant quite see your reasoning

am not against discussion or anything, explaining n re-interpretating a comment is fine by me, to be honest I just wanted a list of things to know, so that when someone comes an views "everything to know about the 17th" that they don't have to read through all this to get to the good bits if you know what I mean, like a reference guide or like a refresher post on the 17th, theres a few other discussions on the 17th's, its just sumit I'l just have to keep pruning, so don't take offensive please if I delete a post just pruning the thread. so far so good. maybe when it gets really long, i'll merge some of the posts into one or sumit

volts drop has now changed!
3% for lighting circuits, 5% for all others! everyone forgets about this one!

Shakey

rememeber, for Public supplies only

I have worked on a lot of private genny supplies, and these are different V drops (higher percentage allowed)

Added content 17th

p20 Definitions - Basic Protection
p24 Definitions - Fault Protection
p28 Definitions - PV

Although basic and fault protection has replaced direct and indirect, I find it funny how the definition describes it as indirect and direct contact in the context.
