rcd protecting tails again

[onions1066]

I know this subject has been done to death and I have my opinion on it but today in a domestic property new build only 3 years old. Meter tails behind plaster no protection with even capping just clipped direct. Dual rcd board in the house. Tails 8 meters long switch fuse outside in Meter box. What would you protect the Tails with?

Window board?....that's just cilly...

then you'll have 2 30mA RCDs in series. not only will you have no discrimination, but you'll have no division of circuits in the case of a fault tasking out the entire installation.

Tel that was n.i.c 's answer as well.

Tell the good old nic ure gonna sling non-maintained emergency lights in every room LOL just incase the installation decides to die ...

They're full of shyte anyway so you may aswell fling some of it back there end

No DC isolator.

Just a FYI, those sunnyboy inverters have a black plastic pull out at the base that's actually a dual pole cut out, and classes as a DC isolator, so that aspect of the install wasn't actually a problem.

probably more by luck than judgement though.

Believe me I'm no solar expert but I believed the dc isolator had to be lockable. I'm probably wrong though.

Just to confirm Glen I know capping isn't classed as mechanical protection I mean even when people normally rough it in they at least normally chuck some capping on them.

Only to stop the spreads trowel.

 

[SPARTYKUS]

Is the house NHBC'd....?

 

[jaypp]

Only to stop the spreads trowel.

what do they use instead, and how does it know it's a spreads' trowel?!!:smiley2:

 

[SPARTYKUS]

Lol.... Clever stuff that capping!

always amuses me when the decorator insists he thinks I should be using capping so that people can tell where cables are with one of them thingies.... Until I bring in a bit of plastic capping.

equally amusing is how many that feign competancy cling to the belief that its somehow `mechanical protection`...



never ceases to amase..

a wood butcher told us we should use it the other week. we almost always do (good practice) but in this particular case was totally unnecesary. don't think he believed our reason, which was as your #66 post sir!

i suppose if you wanted to be pedantic (an ar5e!), you could say it mechanically protects against spreads trowel!!!:wink5:

The next time someone (a customer, a spread, a wood butcher, a wet pants, or a decorator) tries to tell me my job Im going to nail a piece of metal capping to the wall and then proceed to drill it to kingdom come with a wood bit, an SDS, a HSS bit, a large nail and hammer, and ....so on. Won't say a word, will just leave them to study it.

make sure you use the chippys' shiniest one a few times through it!!

Could the tails be protected with a strip of stainless? either flat or folded into a channel?
