yeh not sure either

[quote author=L.Spark  link=1108845227/30#34 date=1111542146]£650 is materials also then or am I getting this wrong  ??? [/quote]


Sorry, yes that includes materials but theres not that much

£20 per light =    £60 for three
Extractor       =    £30
RCD              =    £30
General Mats=   £100 (me being generous)
All excluding vat

Total £260 including vat

Thats £390 labour including vat and me being generous on the materials

[quote author=L.Spark  link=1108845227/30#38 date=1111542824]Mats?! lol

Materials!

Sorry it must be my Devonshire accent  

have you never heard of a bath mat  

PartP requirement "all bathrooms should have rubber mats"

lol

lol, you silly billyyyys!

Greetings  to everyone and especially to the ones like me hoping to go for  the 2391 PRACTICAL exam ...one day

Anyway, a  big chocolate egg to anyone answering these two questions:

1. Re: a periodic inspection on an existing installation .

Whilst doing an isulation resistence test , can one connect DIRECT onto the phase busbar, neutral terminal and earth terminal direct BUT obviously after checking system has been isolated, INSTEAD of doing each circuit individually ?
(all sensitive equipment removed or switches left open where it is not
practical to do so)

2. again to do with a periodic inspection on an existing installation .

If you have no diagrams or previous inspection records and you want to check the continuity of protective conductors and bonding, according to Guidance
Notes 3 , if you have steel trunking and conduit SWA and MICC cable, this will create parallel paths.
Should it be done prior to fixing accessories so as this is a periodic with no records or even if it had records, what is the best way of checking the
continuity of CPC and bonding?

Cheers.
And a chocolate Easter bunny to anyone remembering any funny mistakes from the practical exam. What BIG TIME blunders did you see candidates make ?

PS. don't be shy, chocolate is GOOD for you

Now to me that doesn't really make sense, regardless of fixing accessories, you would need to remove any 'parallel paths' as best as possible, and if you cannot then you should expect readings to be off slightly, dependent upon installation conditions..?

Thank you  for your reply L.Spark.
Part of that had been in turn quoted from  GN3  Anyway could you  not just test the continuity of the trunking, SWA, cable etc, etc ?

Here's a challenging one: on a three phase installation with a double pole isolator when you throw main isolator arm and remove neutral link , then when neutral link removed (Re: INSULATION TEST) ,why does a shorting lead need to be connected between phase and earth?

Unfortunately, I cannot afford to go to college , yet.
Many thanks

Hello L.Spark.
I know....
Anyhow, just so I understand , I  get it in future    can  anyone explain this:

How can you check  CPC continuity which is incorporated  inside steel trunking and conduit , since  this  will create a parallel path  -  
- On a three phase installation with a double pole isolator when you throw main isolator arm and remove neutral link , then when neutral link removed (Re: INSULATION TEST) ,why does a shorting lead need to be connected between phase and earth?

Thank you anyway.
I'm struggling with books right now
