Advice wanted - unhappy with rewire

[Sarah123]

Hi all

Hoping I could get some independent advice on here. We've just bought our first property and had to get a full house rewire on the property (3 bed semi). Our electricians had finished the work within 2 days (2 electricians working on it). When asked when they were coming back, they said they didn't need to come back for a second fix as they'd finished it all. As we didn't know any better, we assumed all was fine and paid up because that said they wouldn't give paperwork till payment was made.

Since then, we have had a few issues. Our plasterer has been really surprised at the poor standard of work - they have had to plaster around all sockets and spotlights in kitchen.

1. The holes made to put in the sockets are generally quite a bit larger than the face of the external socket casing.
2. One of the sockets had a loose wire that was not connected when the plasterer was plastering around.
3. Another socket melted the builder's plug (smoke coming out as well), but didn't activate the trip switch.
4. An armoured cable they put in to light the garage is coming out of the consumer unit and through the floorboards in the bedroom in front of (rather than behind) the skirting board.
5. No paperwork 3 weeks after despite chasing him for this before everything else happened.

Would really appreciate any feedback as not sure if these are common or we really are within our rights to be taking this further? We tried contacting the electrician a couple of days ago, but he's not able to come till Monday evening, but his general response is telling me that he's blaming the plasterer's work.

Thanks!

I never use both earth teminals unless swapping and they wont reach.

just checked stuey's profile. he's new here. a good spanking and a megger on his testes will sort him out. .

You wanna be careful saying things like that. SWD would have a field day.

if you're referring to my last post/pic., then you're talking bolloX. separating the cpc's between terminals is only required with a hi-integrity earthing circuit. eg. with computers. check your eggs regs. and come back with a reason for your comment.

My reason is common sense most electronic devices use switchmode transformers which filter to earth .The regs state " which can be reasonably be expected to exceed 10ma " .Well it's your choice mate .But considering socket outlets come with two terminals !
It appears you have over reacted to a quite Justified statement .It wasn't meant as an insult to your work sorry if you took it that way . 543.7.2 ( 18 )

I've wanted to know how putting the RFC cpc's in separate earth terminals, assist in high integrity earthing, if someone could help me out.

Call building control at your local council, tell them whats happend and ask how to enforce your consumer rights.

ssssimplees it's in case 1 falls out due to incompetent installation.

no offence taken, but you should research as to why the cpcs should be separated betweed 2 terminals.

Again no offence meant .But I have .This has become more of an issue in domestic Installations with the popularity in Led lighting and other newer electronic devices now using filtered PSU's . The main point is safety due to possible earth current transfer from device to device either resulting in capacitor induced shock or even fire . As someone else has stated this can result from a bad connection either by a high resistance connection, mechanical damage or possible capacitor failure within the device itself .

There is no need to seperate earth terminals on a Domestic install. You are right Stuey in what you say but lets not take things to the extreme.
This sounds like regurgitated carp from some college lecturer.
Switching PSUs are a slight problem we are all aware DC equipment has a higher earth leakage but how many does the average house have ?
Do you know how this installation is used by looking at a picture ? This install could be a elderly couple house, not a hackers house with multiple USB sockets and PSUs plugged in.
Led lighting is not usually applicable to either as this on the lighting circuit.

Lets not jump in and insult someones work, leave all this rubbish to the Facebook groups

I hope this isn't one of yours ! Ring main Earths are one cable per terminal not two as in your picture

It’s not a fudging ring main!

 

[John Arnold]

What a terrible installation. Massive holes made for sockets really bad looks like they used an angle grinder to cut those and damaged the skirting board to. Height of consumer unit far too low eye level please. Where is the covering protection over the wiring?telectrix so right mate. That loose wire has no screw markings on it I guess it was not secured?You have my sympathy I hope they come back and correct their faults and give you your certificate( do not hold your breath).

I have seen that type of plug burn before. When a plug on a small fan heater gets stood on and brocken any plug to hand is fitted on the heater as a replacement. The trouble is the replacement plug is not the same grade of plastic as the original and melts. That burn damage is on the builder or plasterer not the electrican.

Interesting to note the various comments from working electricians ... not a consistent set of comments. I think the polite ones are valid and illustrate that there is room for interpretation. One man's masterpiece is another man's pile of ****!
Are the metal boxes earthed?
Sharing or not sharing earth terminals on a ring cpc is something of a red herring in this context. I think that the reason that high integrity earths are run separately is because computer and other similar equipment (including switched mode PSUs) use filters to meet RFI specifications (to control imported and exported RF noise). They employ filters that connect reactive components (capacitors and inductors) between line conductors and the cpc and this can induce RF currents in the cpc cable linking the equipment to the system ground point. If we really care about controlling RF noise, we should avoid the use of any ring circuits at all and have one system ground point to which all cpcs are connected directly to the ground point in a star network.

the purpose of separating the cpc's into separate terminals is in case 1 becomes loose or snapped, you'll still have earthing (protective and functional) to equipment .
