Commissioning a busduct. My contractor has installed a 2000amp aluminum Busduct in a 17 floor office tower.
The specifications state you should undertake field quality tests on site, which are more stringent than the manufacturers' static tests, for the following:
1, Perform resistance...
Hi all, if I’m getting an insulation reading of 0.03 across N & L on a lighting circuit what would cause this? Neutral earth, live earth, are in the acceptable realms.
Hi all, I am an electrician working for a OEM machinery manufacturer based in Germany, we are the local hub that is now taking over the installation of the machines in the UK, the machines are liquid filling, packing and palletizing.
So on to my question, as I understand it the machines...
Morning everyone
I’ve recently bought a fluke 1662 as my megger 1741 broke on a site last week.
Does the fluke have the same capability as the megger or do you just have to take the lead resistance off after the test ?
Hi, just looking for some advice,
Do you need any governing body to be able to do Fire alarm & EM testing? Im awaiting my NIC or Napit but im hoping to secure a little contract doing these (ive done hundreds sub contracting)
Thank you!
Hi 👋
I have my 2365 level 3 and currently working on my 18th edition. I work in construction but not electrical (hoping to soon!)
I just bought my first tester, the Fluke 1664 and I plan on building a test rig at home so I can practice with it
Looking for some ideas for useful things I could...
Hi
I know I have to do more testing but I just want to see if there is something I’m missing.
Customer said light fitting in the loft was crushed causing the breaker to trip. I thought easy fault to rectify which was very naive of me.
I arrived disconnected the damaged switch which was in...
So I’m an apprentice and I’m just trying to get a better understanding of the science behind this because the electricians who have said it have been quite vague and not properly explained.
Recently testing L-E for a circuit which was 0.02 ohms and the electrician said I will have to remove...
Hi,
I would love some help understanding an issue I’m having on a 16mm SWA cable running from the CU in my house to the CU in the shed.
I believe there is a problem with the cable (possibly between E and N), and I have used a multi-meter to do some checks on the CU (shed side) and below you will...
I recently just done my AM2 resit and in my inspection and testing, despite the invigilator watching me do the tests, I think I may have forgotten to tick the RCD test button on the Electrical Installation Certificate despite actually doing it the test.
Would that mean an immediate fail for not...
Forgive me if this is easy to search - I was not able to find anything obvious here or on YouTube. I've got an outdoor circuit that has failed. Specifically, one outlet failed and then the second one went about a year later, with no trip of the breaker. How do I test the wiring to make sure it...
Background
Two weeks ago, lightning struck a tree in our yard. Many circuits tripped and several electronic devices failed. There was a strong smell of ozone/electrical burn throughout the house that has since dissipated.
Two AFCI breakers are still problematic. Both serve bedrooms (hence AFCI)...
Hi everyone,
I'm nearly on my AM2 test and really enjoy the industrial side of things so I thought I'd learn by asking.
I recently came across this note about IR testing PRIOR to connection? Can someone just explain how you would test if there was steel conduit and the earthing arrangement...
Hi,
I'm a little confused confused is someone can shine some light on the amendment 2 way of doing IR.
I know you have to do one 1st fix at 500V DC and then final one at 250V DC when all cables.
What I'm confused about is GN3 states:
"...sometimes these cables are terminated without further...
I was thinking about getting qualified to do this for a charity. I already do the necessary stuff to put the electrical donations into the shop floor. They are charged too much for this service under contract.
I need insurance, certificate, kit, cards..and I will be funding it.
I've had a look...
Hi
I am a sparkie based in London.
I am trying to shift from installation and maintenance to Testing. I did not use my 2391 for a number of years, but eventually decided to make a move to Testing. I tried to search the internet, but there is no info on any Employment Agencies hiring mostly...
Hi Guys,
Currently on a 3MW Solar farm job and will soon be coming up to the testing stage of the project. My question is, where do you do your test? There are String boxes at the end of every row, with isolators inside them for local isolation. There are then duct grade single core cables that...
Hi Im an apprentice and just wanted to clarify domestic style wiring since i work industrial and don't deal with conventional wiring. in college and the AM2 the only exposure to testing lighting is of a single point that may be switched either one way 2 way or intermediate. that doesn't worry me...
Hi all,
Testing question for you.
I'm currently testing an existing domestic installation. The wiring is about 20-25 years old.
We have rewired some of the older circuits and added newer circuits too. During my insulation resistance test, over two-thirds of my results were coming out at...
Hi guys I have been instructed to carry out leakage testing on the 3 microwave we have on site as I am the only person on site with 2377 but I'm unsure if the microwave leakage testing req a different qualification as this wasn't on the course or I'm my notes.
any guidance welcome.
