Finally fniished off a periodic last week of which the whole place pretty much needs gutting. Outside lights wired in T&CPC with damaged bulkheads, outside catenary distribution wired in T&CPC also. Of up to 11 db's this one is by far the worst.... . . . . . . . . . . .

Does anyone no a brand of consumer unit that accomodates installation in narrow areas. Doesn't have to be too narrow, but a standard 17th edition board wouldn't suffice and RCBO's are a little out of my clients budget. I remember RF had posted an image of one a while back (I think it was RF)...

Hey guys, quick question for those with NICEIC enrolment. (If you don't have it, but can help also, then cheers). I am having to change my scheme from Domestic Installer to Approved contractor to meet the demands of some clients. I was planning on having the Periodic Inspection Reporting...

Hey all, wonder if you can help? Had 2 phase go down on a distribution cable at one of the schools I regularly work at yesterday and the result was needing to get a 115kva generator in situ temporarily. The cable had been jointed somewhere and it appears that that has failed. (0.0Mohms across...

Hi all, I got a call from a family member who asked me to come and look at possibly putting in a socket or two in his newly acuired home. He has just been offered it from a housing associastion for an exchange. Anyhow, I popped over and noticed it had just been re-wired and so scoped out...

Was doing some testing last week of 30 or so circuits in pits. With 2 pits to go, I come across this. I'm pretty sure this socket's IP rating isn't suitable

Was pulling out supplies from a weekends racing this morning to find this little gem.. It would appear that someone couldn't find a polish socket outlet. Unfortunatley, the IP rating of the Tesco bag had been compromised on our inspection :( We unplugged the...

Has anyone here successfully purchased online via the NICEIC Direct website? Everytime I try to add something to the cart I get: ''An Internal Error has occurred.''.... with a load of other script. This has to be the first time the NICEIC have failed to take money from me and I'm...

Hello all, Maybe you can give me your experience or ideally reference to some text on this one? I'm in the middle of a re-wire of a domestic property. The property was stripped back to brick, and it is to be letted and so naturally part M's guidance of accessory heights has been...

Has anyone here sat the 2377 course (both parts)? I've just had a group of 27 in over 3 days and my class got a 100% pass rate, dead chuffed :lol: It was very informative, I used the 3rd edition of the ''Code of Practice for in-service Inspection & Testing of Electrical Equipment'' for...

Hey all, I went to do a quotation today for a demolitions company who are decommissioning a former high street store. It has over 20 db's and they need certain saftey circuits left alone or temporarily supplied if unsafe. I went through it all fine and towards the end the client asked if I...

Hello all, I have put an estimate in for a rewire. On the specs sheet from the client it had 'Loft aerial installation to receive digital FM & TV signal' He requests a TV/FM point to be installed in 4 rooms. I had originally omitted this from my estimate as it wasn't really something...

I'm just gonna waffle a bit hear but please bear with, I do have a point... I used to work for a Mr Electric franchise that covered a city area. I came on board as a QS from my previous job at a local council. They said that they needed me to turn things around as their NICEIC annual...

Hey all, I have a kewtech KT45 which is behaving funny. I tried testing yesterday on a TP&N DB we have just put in and it was only only reading 129V at L1,L2 & L3, whilst another tester of mine verified a healthy 242V. Then when I attempted to measure the Ze on L1 it just started flashing 0.06...

Want your advice if you please, I've been asked to supply a quotation to supply electric heating to a building which is being converted into a nursery. Due to the nature of the building I suggeseted underdfloor heating but they've decided they want fan heaters. So I've looked at the...

Not sure wether this belongs here or in the central heating section. I had a request to inspect a client who had no hot water, and it turned out she had a three way switch controlling her immersion. It positioned as mains, off and economy 7 supply. Now the switch is no longer operating on the...

O.k. where to start, I have only been working for my company for about a month now. I have come on board as QS but they've made me manager in that time. Now I could spend ages saying about the things they've not been doing but I guess thats another thread altogether. Anyways, last year...

Ok, well I've got the 17th and pre-orderd the o.s.g. I also have the NICEIC Learning guide for the 17th edition (a perk with lecturing) Now I want to get some more books that are being issued for the 17th. I have religously always bought Brian Scaddans books in the past, and have to admit...

Apologies guys if this has been discussed, but I just have enough time to post this before a meeting.. when changing a consumer unit, which way would you do it: Periodoc Inspection Report>Change C.U.>New Installation certificate Change C.U.>New installation certificate Periodic...
