Rcd protection

[Farmelectrics]

Question well two. First one there was an electrical survey carried out by the landlord or so I'm being told over the phone regarding no rcd protection on sockets in a local restaurant kitchen, but my question is the installation has been like that for a number of years so wasn't required when installed my question is do they need to be changed ro an rcd or rcbo . Second question new water supply has been installed to an out building and they've said it has no earth but the water supply is in plastic your thoughts please

Question one...Is this remedial work after an EICR has been conducted? If equipment is not likely to be plugged in and used outside and no external sockets then would be a code 3. If the likelihood is there or there is external sockets then code 2. If they wanted a satisfactory report then obviously the code 2 would have to be rectified.

Question 2...if extraneous then requires bonding, If its not extraneous then doesn't require bonding. If above 22Kohms when tested its not classed as extraneous.

Thanks lee no it's not been an eicr sounds like it's just been a visual I'm going tommorow to look at this report we done the kitchen about 15 years ago and I'm sure there was no need for rcd protection at that time so surely the sockets don't need to be rcd protected I could easily say yes you need a board change but it's not needed in my eyes

If the landlord wants the board changed I wouldn't be talking them out of it

 

[Farmelectrics]

No true. I'll see tommorow So explain this 22 k ohms reading so I connect an r2 lead back to the met and test between we're as the water supply is plastic

 

[Risteard]

I'm sure there was no need for rcd protection at that time

What was required at another time isn't relevant to the Report today though, is it?

I would just quote for whatever they want.

 

[Leesparkykent]

Is the consumers pipework also plastic?

 

[Farmelectrics]

Yes risteard your right problem is it's sort of like family's on the others side so trying not to get to involved lol there trying to sell the place so there not wanting to lay out any dough

 

[Farmelectrics]

Not sure lee will have a good look in morning just trying to get a heads up off you guys before I go sort of have some answers to throw at them lol

Thanks Pete interesting

How is a plastic pipe going to introduce anything! It plastic.

 

[Leesparkykent]

If the incoming pipe is plastic and consumers pipework is plastic then its not going to be extraneous. If the incoming pipe is plastic and consumers pipework is copper then the chances are its not going to be extraneous, unless the routing of the consumers pipework makes it extraneous. This video by Chris Kitcher explains the 22Kohm value really well..2:15 minutes onwards. http://routledgetextbooks.com/textbooks/_author/kitcher-9780080969077/video-02.php edit: Didn't see Pete had posted the video 1st

? The customers pipe work is not a service that may introduce voltage is it!

If the consumers pipework is extraneous then it needs bonding.

 

[Simlec]

If the consumers pipework is extraneous then it needs bonding.

But we are talking about a plastic pipe that's not the customers nor will it be extraneous because it can't be as its plastic!

Well that's obvious and goes without saying doesn't it? When bonding what side of the stopcock do you bond.....the consumers side! If the consumers side is extraneous and introducing an earth potential then it requires bonding. The consumers side could be extraneous even though the suppliers side is plastic depending on the routing of the consumers pipework as mentioned in an earlier post that you have seemed to of jumped on. For example mdpe incoming water pipe, stopcock the consumers copper pipework that re enters the ground/earth to feed another part of the building then its totally possible the copper pipework could be extraneous.

I had that recently in a small toilet on an exterior wall . The incomer was plastic and not bonded.
The copper pipe fed the toilet and sink then disappeared under the floor to feed the rest of the house lying on the concrete base. (wet)
It also fed an outside tap up the garden , this was in copper too.

The question was "will the plastic incoming water pipe need bonding" The answer is NO its plastic..
Now if the question was "incoming water pipe is plastic (and probably gas too) will the internal metallic pipe work need bonding?" The answer would be go around the building and test the exposed parts and bond if required.

Have you seen post 7 and post 9? Which also leads on to post 13 to which you quoted.
