I am in training and decided to do some dead tests using my second hand Fluke MFT 1653B on an upstairs ring. I did the tests at a socket rather than at the CU. Results end to end L - L 0.74 ohms, end to end N-N 0.76 ohms, end to end cpc >2000 ohms. I checked all the sockets on the ring and...
Hi,
I`ve been to a site today and noticed some units I`ve got have huge voltage drops. Voltage was fluctuating between 170V and 280V and on some units, I`ve had 330V.
I went to the DB board:
Between live and earth some circuits were showing 217V and other one were showing 270V.
Between Neutral...
I'm trying to test if there's voltage between my ignition and the solenoid. The starter won't crank or click so figured I'd start here but am not sure if I'm doing this correctly. I have a male/female connector from the ignition to the solenoid. I disconnected this, connected a probe to the...
Hi people,
I'm having a brain fart moment. What is the minimum distance between enclosures, with doors that are facing each other?
In EN60204-1:2006+A1:2009 section 11.5 said " In the case where such parts are present on both sides on the access way, the clear width shall be at least 1.5 m."...
I’ve got a hell of a lot of scrap cable in my garage. I know it would take a long time but is it financially beneficial to strip the cable or does it not make much difference?
I think i might of asked this before but
Here goes again, on my flat cu with the mcbs off if I use my voltage tester between a lighting circuit and socket radial I get continuity?
Why is that?
But of I power up one mcb the others don't get powered up.
Hello thanks for reading - I am having a 3 bed semi rewired and narrowed it down to 2 electricians.
Both a not on any register as far as I can see.
One will do the work in 3 days (3 people doing long days) and get it signed off under the Third Party Certification scheme
The other says he...
I am having trouble determining the significant differences between Eaton's residential & commercial duplex receptacles:
Model #270W-10-LW (https://www.lowes.com/pd/Eaton-White-15-Amp-Duplex-Outlet-Residential-10-Pack-Outlet/1001438408)
Model #BR15W-10-LW...
On my cu at home I have a continuity reading between my ring final circuit and a radial circuit of 114ohms between live conductors.
When I test continuity from each breaker.
Why would that be? Break down of cable
If I turn one off and leave the other on I don't get a voltage.
At what point...
Hey, my downstairs hallway light switch is a 2 gang but doesn't control my upstairs hallway light (and just a 1 way for the upstairs light). After inspecting, there is unconnected T&E thats runs to the upstairs light from the downstairs 2 gang switch. Now I know that can't be used as a 3 core...
I am finishing my basement. Come across something I didn't see before. I have two different receptacles in my basement and each one has its own breaker at the breaker box. And there is cable running between these two receptacles. I would love to learn why there is a cable running between these...
Just tested the end to end resistance on a ring main at a socket outlet. Readings are spot on however when changing the crocodile clips I notice that I have around 600ohms of resistance between the Line and Earth conductors. The system is TT. What could be the cause of this?
Hi all
Downstairs lighting circuit isn’t working so tested voltage at each fitting and getting 180 live-neutral and 240 live-earth. Have checked continuity from board to each fitting and got a neutral all the way around the circuit so I’m a bit stumped on what the issue can be.
There is access...
So up until this morning I thought I had seen most faults in an electrical installation, but this one today has me stumped and I’m not sure if I’m being stupid and the issue is staring me right in the face! long story short we went to a domestic property with a TNCS to install a supply to a...
Recently, I have decided to switch to LED lighting instead of any other old school lighting. Our government has taken the initiative of replacing old lights with energy-efficient LED bulbs. But there is still a debate about which lighting option is better, is it LED or CLF.
Give me your...
I have never actually had to make an electrical system into a TT. I have added rods in order to get an effective Ra but never had to (for example) install a TT on a new garage or shed.
It's best I give an example with regards my question..
A new garage has a supply taken to it from the house...
Hi looking for some help about faults and symptoms and difference between short circuit, dead short, and overcurrent to know which fault you have.
Is short circuit line and and neutral fault
dead short zero resistance and a tripped breaker
And overcurrent to much current in circuit causing...
Hi all,
I’ve got a question about the Dimplex Quantum High Heat Retention Storage Heaters. I’ve been in discussion with a supplier about these. He’s provided a few quotes. He’s knocked about £350 off the price by offering my the G series Quantums. He says these are exactly the same as the RF...
