Hi all. I've recently bought a bungalow. It currently has a armoured cable between the house and garage which spans less than 1 meter. The height of the cable is 2.3m and directly under this is the side gate to access the back of the property.
It's old wiring so will be replaced, but I've had...
At long last my wife is getting her new kitchen and the contractor will be running 10 or so new circuits from a new sub panel. The sub panel, unfortunately, is on an outside wall around 35 feet from the kitchen. The wiring will have to go down the wall, into the crawlspace under the house, and...
I removed a fuse and before reinserting did the following tests using test lamps. Live side - Neutral = 230V, Dead side - Neutral = 0V, Live side - Dead side = 0V.
I then used a multimeter to check these results as I was expecting a potential difference of 230V between Supply side and dead side...
Hello, I don't know if I'm in the right place for this publication, I apologize first of all. I did a search, but I didn't find anything.... Does anyone know the difference between these two FLUKE 1663 models, where one comes with the RCD test selector in yellow and the other in white? What is...
Hi all,
I was called out earlier today to a house where a plumber was fitting a new mains electrics shower. He wanted to know if the existing cable was of a suitable size. I am a recently registered electrical contactor, however I hadn't come across this issue before. The cable was a 6sq pvc...
Hi Guys,
I love colorful LED light strings. I've been wanting to hand some around the house and finally got around to it.
I purchased a few LED light strings that seemed high quality on the web and hung them around the house. The lights worked well at first, however they soon began...
I am upgrading an old 100A semi flush outdoor overhead panel to 200A solar ready, panel. Was looking at Square D SC2040M200PF, but this appears to be designed for bottom feed- with option for top feed. Does not appear ideal, and my installer says might be a real PITA. I am not seeing many...
Is there an obvious reason why I can't just fit a plug onto my LED soffit downlights, fitted with a 5amp fuse and plug it into a socket rather than install a 5amp fsu? I'm fine with the plug being permanently plugged in as the socket gets no use anyhow. TIA
I recently had my 50yr old 100A main panel replaced with a 200A Siemens panel (MC2040B1200EFC). It is the incarnation with the 200A main breaker at the bottom (earlier versions were center fed which would have alleviated my problem). At the same time I had the electrician add a 50A inlet for a...
I've noticed a strange voltage reading between the water in my spa and natural earth ground. The reading varies between .35VAC and .7VAC. My wife noticed a small shock from the water after inserting her finger in the spa while standing outside the spa.
I tested the GFCI and it is working...
We're renovating our kitchen, and I have parts of the wall open and can rewire circuits right now if needed. We currently have three 20A circuits serving the kitchen, as follows:
*Circuit 1: fridge, microwave, toaster, outlets.
*Circuit 2: disposal, beverage cooler (5 cu. ft. mini fridge)...
I am wiring 2 outlets in the ceiling to control 2 plug-in florescent shop lights in my garage. The 3 ways are at each side of the garage at the 2 entry doors. The way I have it wired right now, both lights come on at either switch but turn off if either is unplugged. I would like both outlets...
What is the difference between a Hager MT132 and MTN132 circuit breaker? (apart from the fact that one has an 'N' on it and the other doesn't). I need to fit (or get fitted if I can ever get a lecky) an MT132.
Thanks
Brian
Hi All,
I'm trying to learn about discrimination and I came accross the LSIG characteristics of an Air Circuit Breaker. Howecerm there is something I really cannot understand about the Tsd. What's the difference between ON and OFF in the intervention? Thank you in advance
TN-C-S supply, shocks/tingles from earthed sink.
Latest NICEIC test (2017) from landlord shows 200Mohm resistance between E and N
As above, do I have a floating neutral, is this causing a leak from N, via bonding on sink to true earth (solid kitchen floor)?
Hiya Guys, I have a gas central heating boiler that is not switching on at all.
It's connected to a clock timer and then to a fused spur.
Boiler technician was out today to say the boiler is fine and I need an electrician, hence this post !
He said we have cross polarity on the fused spur. He...
Hello,
I am currently investigating how to connect copper busbars or cables to a titatium busbar on a DC voltage system.
What are the requirements/standards?
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...
