Hello everyone
i recently got a job on replacing a BMS panel in a plant room. the NEW panel i installed except the control side of the install also feeds the mains for a few gas boilers, immersion heaters and cylinders, pumps. etc. I am going to do the testing on that and i...
I am confused about battery testers for house hold batteries, AA, AAA, 9V, etc.
Recently my smoke alarms started chirping so I changed the 9V batteries and no chirping.
However, the replaced batteries tested good using GBT-500a battery tester.
I was told that batteries need to be tested under...
Hey all,
Could do with some help.
I had a company recommended to me who quoted me to do an EICR on my rental property. (£265). I thought this was quite expensive but as I've been messed around no end by tradesmen I thought I'd go with the recommendation and pay the extra.
I also asked him to...
Hi, I am currently with New Trades Career doing Electrical Installation level 2 & 3 and have come to the stage where I am doing the preworkshop health and safety test but it's a bloody headache, I have failed it once now and have a strong feeling I am going to fail it again. I am struggling and...
Just wondering what this might be.
It was a brand new Schneider RCBO fit into an older Square D board. RCBO fit on the non RCD side. Everything working fine, load is on and pulling. I always press the test buttons on the RCBO's just to check, and this time the switch 'stuttered', sort of...
I've seen several videos on these, half of them show an MCB in the 'on' position protected by an RCD also in the 'on' position, earth lead on the earth bar, neutral on the neutral bar, and live on the MCB's line screw terminal.
But then i've seen other videos where the earth bar and the...
Just wondered how we would know a 30ma type A rcd/rcbo will trip at 30ma,if we
can only test it at 350ma?Think I must be missing something.Thanks for any help.
Regards,S
Got a sub main board with an RCD inside. Need to test that but whenever I test it it sometimes trips the RCD from the main board. I need to test the RCD from the sub main board. Any suggestions?
My thoughts are to bypass the RCD at the main side with connector blocks momentarily but surely...
Doing some testing today on a Wet Room installation.
Fed from its own small CU. And consists of
2 x seperate 50A (for 10.5kw shower) circuits
1 x 20a radial for underfloor heating. This runs direct from CU to a fused spur and then from the fused spur to the UFH controller.
1 x 20a radial...
Sitting my pre employment sectt test soon. Revision material provided is very basic with only a few questions. Can anyone please help with where to find additional revision materials/mock tests, or give me info on what the exam involves.
Thanks
Can I put a key switch on the ceiling for the non maintained emergency light illuninare. This is so that they are no wire trunking showing on the wall.
I was called to a hall where 6 Ansell maintained exit signs were all dead. They were installed 4 yrs ago. The one that I checked had mains live was connected to L andL1 and the battery was flat; this should light a red led to indicate a faulty battery but nothing showing. There is a reset...
After completing a new RFC or modifying an existing one, I will always test continuity across all 3 conductors at the Consumer unit. I use the continuity function on my Fluke 2 pole tester to do this. This is done whilst the circuit is dead.
Prior to this, I am very diligent with the conductors...
Hi all just wondering if I could pick you brains, I was doing a ze today on a consumer unit, 80amp rcd main switch, (the test button wasnt functioning so I was already thinking as to what caused this to blow) I disconnected the main earth, turned the main switch into the off position, I then...
I am self-teaching fault-finding and testing, but I can't wrap my head around insulation resistance tests.
From my understanding you send 500V for domestics down the conductors using an Multi-Function Tester,
and the values should be over 1M Ohm, now my question is why should the resistance be...
I am looking for someone to carry out an in service inspection and test of a two bed flat in Cardiff and also check that the under floor heating is in full working order. Property is vacant and the testing can be done over the next couple of weeks,
Has anyone used the Ethos 8600 test adapter?
The ethos-instruments websites have a user manual button, but nothing downloads. There are no youtube videos as you get with other brands of adapter and the basic leaflet included doesn't have sufficient info.
Pre-purchase, I was concerned about...
