Hello
Just opened up a consumer unit, to find two circuits (lights and extractors) coming out of one 10 amp mcb. This isn't right is it? What should I do come the time to test and record results? Where would I write them down?
I've always thought its 1 fuse/breaker per circuit? head...
I did a survey of a larger detatched house today. A poor prospect due to shading from 20m high trees and surrounding houses. Also has lack of suitable roof space.
Real shocker was current electricity consumption. 12,000kWh/a!!!!!!! I would have considered 6000 on the high side. They have a...
Hi Again Guys,
I've just wired a garage unit and have fed It from a 32A MCB from the main cu in the house, so its a new circuit. I have tested the new unit and all is fine. The question I have is.. Do I have to test all circuits in the original cu as well and record results on the same test...
Hi, Guys,when measuring PFC-PSCC on 3 phase supplies,I know that you test between live conductors L1-L2, L1-L3, L2-L3 and then all 3 to Neutral and note lowest reading obtained. Then all 3 phases ( is that right term for C&G? ) to earth. Then neutral to earth and lowest reading obtained recorded...
Hi guys please bear with me as I am new to the electrical game
I have done a private job and run a garage board to a shed with a six mm amoured fone all relevant test on the curcuits
And done a zs at db but do I have to r1 r2 the sub mains to put on the test results or is tbis not needed and...
Recently came across a 6 terminal 20Amp junction box with 12 T&E cables coming out of it and an additional chocy block inside! Is that a record? It was being used as the only distribution box for the upstairs lighting of a 3 bed semi.
I wanted to fit a 13th but the earth terminal wasn't having...
I will be installing a new Ring main for a kitchen install and have come across a cut-out that is totally new to me.
Has anyone seen one of these..and how do I record its details on my Certificate.
I'm testing a car park lighting circuit at 200m long. 4mm singles to first point at about 100m and then reduces down to 2.5mm. Trunking used as additional CPC to reduce Zs values. How would you record that on a test sheet? And is there a regulation about downsizing?
I was doing a fuse board update the other day and normally I use duel RCD boards with mcb s but instead I used separate Rcbos due to the customer specifying these. I prefer fitting Rcbos due to just that one circuit is disrupted when there is a fault.
when quoting for the job I carry out a...
Hello, all. I have been a member here for over five years and log in most days, but it appears that I have never posted anything (following a nudge from Dan). Probably because I have nothing much of value to add to the discussions.
I find the forum a valuable source of information, particularly...
Hi Guys
I've just completed my first 3 phase installation. A 3 phase CU (Proteus) in a church extension. There are 12 x 230V circuits feeding sockets , lights, heaters, etc.
1. Do you record all circuit test results on the same page or use one page for each phase?
2. Do you record Zs at DB...
I frequently get asked to inspect a light fitting or a socket to ensure safety. Customer is asking for a cert to confirm. How can I record to give customer a cert without providing a EIC cert.
depending on the job I usually test ze zs and IR and ring continuity if required.
i use to visit loads...
Hi can someone please endorse or recommend a data logger to monitor and record refrigeration compressor on/off starts and a data logger to measure and record KWH. Thanks
What is the best way to confirm r2 and R1+R2 when the circuit is routed in conduit and this is used as the cpc?
I have used wander lead and got continuity at all points on the circuit for the cpc.
rn and r1 are within 0.03 of each other so no problem there.
just how to confirm that the...
I am used to niceic forms so please bear with me! In the insulation resistance section it only has two fields for recording details which are live -live and live to earth, surly I have to record more than a live to earth for a radial what about neutral values!!
Got a call a couple of days ago to a boiler which had been looked at by a gas guy who advised of an earth fault and that he had isolated it. So I bowled up today, there was a VOELCB right by the BS3036 CU which had excessive charring on it, some fuse carriers were crumbling others were cracked...
