test

Why would a rccd fail straight away after pressing the button on tester ,

Good morning all, I have recently carried out a rewire on a one bedroom house and installed a new DB. As I am not part of a CPS I cannot complete an EIC for the install so was going to get someone who I know to do this for me. The property owner now has a cash buyer to but the house and is...

Hoping someone might be able to help. I’ve seen an ‘adaptor’ that allows 2 test leads to run from one port of an MFT (doing IR test). But, can’t find anywhere to buy it. Anyone know where I could get one from?

I am about to put in a copper rod to TT a garage. I have a megger 1731 but do not have the Earth spike test kit. I will be able to test the Ze once the rod is in place and wondered what the difference is between testing the Ze and testing the Ra with a spike test kit? Is it sufficient to just...

Anyone able to make use of these ? Having a clearout and have an old insulation/continuity tester and a loop/rcd tester. Alphatek 1601 and Metrel 2120. The Metrel has a broken screen glass but functions. Maybe good for showing the basics to a trainee or apprentice ? Free to anyone willing to...

Hi. I've already got the initial insp. and test and want to do the periodic, EAL or C&G. I'm struggling to find anywhere that runs it around the Kendal/Lancaster/Preston area of the North West. Any ideas.

Hello all, I’m now overthinking the - Prospective fault current test for the 2391 practical, the exam boards will be a 3 phase and a single phase board. Do I test the three phase board and double the highest and use that for both DB’s or do I do one for 3 phase db1 and sep one for single phase db2

Hi guys Im wondering if anyone can help me out, Im due to sit my Fica test in a couple months for the end of my electrical apprenticeship and Im wondering if anyone can give me a heads up on the motors and the door entry system because they are the two areas Im least confident in. Any advice...

Hi i need some advise on writing out a electrical cert for a control panel,i have only tested distribution boards has anyone done certs for control panels?. My query is the panel has overloads for motors,ive done my R1 R2 tests etc how do i record these on the schedule as there not circuit 1-12...

What do you guys who carry out eicr on commercial premises with multiple consumer units do when putting tested/next test stickers on each consumer unit, do you just put one at origin, one on each cu? And if the result is unsatisfactory what do you put on the next test date due, if there are...

Installed a new radial circuit in a garage from an existing CHINT garage unit. All functioning well (tests fine) until after the RCD test. Then everything, lights etc stops working. On investigation, while I've got 244V at the incoming side of the main switch I'm getting a reading of...

OK, Stop laughing at the back! SO, I'm house hunting and, ignoring the number of beautifully decorated houses with shite electrics - I also want to be aware of any damp issues. This led me to try using the trusty Megger with sharp probes to test for damp. This appears to work, or at-least is...

Hi have wierd dilemma, looks to be 3 phase - 4 wire system so testing am getting this L1-L2 Nothing L2-L3 450v L1-L3 450v L1-N 230v L2-N 230v L3-N 230v Why no L1-L2?

I replaced the emergency lights in a small block of flats about 6 months ago, but the last time I did a 3 hour emergency light test was a year ago. Common sense says that I don't need to test the new emergency lights until they are a year old, but any clarification appreciated?

First periodic test since doing my 18th edition top up months ago and I don’t have it t hand. So until I get home to have a nose and realise this question is ridiculous I need reminding. 3 circuits (lights x 2 and boiler ) are not on an RCD. The installation is over 10 years old as the last...

Okay may be a thick question but I have an RCD tripping on 5 x test 180 at 40ms. Pass or fail? GN3 says must not exceed 40ms BBB says within 40ms My tester says computer says no. To be honest I am recommending it be changed anyway but it will be a call back on a new build for another spark so...

Hi all, Hypothetically speaking of course, If HMRC were ever to investigate someone can they contact your scheme to enquire about how many cerificates and jobs you have done to compare against what you have declared to the tax man?

Hi, was wondering if anyone could offer advice for an apprentice practical test coming up with Western Power, I passed the first stage (Knowledge). ?Have been told it will also involve climbing electricity poles, I am still in first year so have no qualifications yet? Thanks

I need to clarify something that's rattling around in my head. I was taught when testing lightning protection systems that the maximum permissible combined electrode readings shouldn't be over 10 ohms. So we would test all the electrodes individually then work out resistance in parallel. We...

Hi, I just have a few questions in regards to testing an RCBO circuit Is there a requirement to test at either the furthest point or the DB or is it down to the testers discretion. Do the test results differ? What tests on a circuit will trip the RCBO when you are away from the DB. Is it...
