Napit is cheaper I've been with them for years no issue

just a thought, what output is the shower? is the switch a square 40A one? wouldn't be the first i've come across with a 10.5 Kw shower on a 40A pull switch and yes they are usually toasted!!

Be careful your halo doesnt slip and choke you!

Secure I understand now. Yes they work as they should on x1/2, x1 & x5 Tests as said it was questioned by a couple both I believe are trying it on to lower the offer price! Final full tests to be done when i have time.

Bas Firstly I am the builder and the electrician on the project and I have done it by the book butbecause 2 different buyers builders have made snide remarks I asked here to see if I might be wrong I am not perfect like the "keyboard experts" that have to pop up on here ! No the extension...

Explain please? Not sure what youre asking?

better that than under! :lol:

the issue is that each time Father in law gets a buyer some jumped up little prick builder comes looking for faults (that don't exist) puts the fear in the buyer who then backs out! happened 5 times so far but only twice has the elecs been questioned. I want to be able to say with certainty it...

CU1 is a Hager and CU2 is a British General Nexus CU MCB's have been changed to suitable sizes but otherwise as supplied from BG Nexus

the 63A is in the main house CU supplied from a 100A isolator switch with 2 6A lighting circuits on the same busbar separate RCD 30Ma has the 2 socket circuits and a cooker circuit in the same box this feeds CU 2 in the extension the 2nd has a 100A iso and 2 x 63A 30Ma RCD's supplying the...

correct the boiler is dual powered and has a high 32A input for the heat element (10mm T&E) and a low 5A for controls (2.5 T&E) and is clearly marked as having 2 power sources

I don't need to pay for the EICR as I can do it. the question was what if anything is incorrect in the install as I believe it is correct although close to limit on the 63A MCB - 2nd CU via the 10mm cable. I'm confident that it is safe and within limits but looking to see what others think. have...

thanks yes I thought the 63A was a tad close and yes it is a type B MCB as I stated the chances of everything ever being on load is highly unlikely and it has never tripped in 2 years yes it needs signing off hence trying to get the definitive answer as its my father in laws place we built...

the "sparks" were both associated with builders!! need I say more! both were invited round by 2 separate buyers the first buyer has backed out the 2nd is iminant!! its a house connected to family and i'm not 100% sure on whether its right or wrong (only part qualified myself and not come across...

So having looked up the onsite and the main 7671 books I cant find an answer!! scenario main house 2 consumer units 1 normal 10 way and an economy 7 cu separate. then a 2nd CU supplied from 1st in an extension and a 3rd supplied from 2nd in a shed the 2nd one is the one in question...

BG fitted a Hive to one of my customers boilers recently took 2 engineers 3 visits to fit!! FFS :lol: :lol:

well if you've got lices from your exes i'd go see a doctor!! lol :lol:

http://www.potterton.co.uk/docs/Potterton_Performa.pdf all the info is readily available for the installation (page 9 relates to flue positions)

agreed!

so you have 10 rads? each rad needs approx 1.5 KW so thats 15 Kw your boiler is 28kw? think the problem lies elsewhere!! the boiler is perfectly sized in my opinion, maybe radiator sizes are wrong as the installer just used "what he usually uses" and didn't size them for more than 1 outside...
