Just a quicky. I knew I'd read something about selectivity but in this case it would be really fiddly to get a selective RCD upstream of the board in the garage to agree with BS7671, and the board doesn't really allow me to get the MCB off the RCD and be independent. If I was going to do any of...
House is TNS, and all lights both inside and out are/will be LED. As for the wattage requirements, have taken the values from the manufacturer from everything both in place and planned, along with expected inrush currents from the workshop tools.
Garage is attached to the house, and the feed is 6mm T&E from the house consumer board (from 32A MCB) to the Wylex board in the garage, approx 10m run clipped direct currently. MCB in the house is protected by an RCD which I've tested and works.
Yes, I agree with the possibility of further...
For a change its nice to have a clean slate to work to. Client wants their garage rewired (and boy does it need it!) so they can have the following:
Washing Machine, Tumble Dryer, American Fridge/Freezer, Outside socket, outside lights, workshop tools all 13A type such as circular saw etc...
Yes, and I'm pretty sure nothing was touching anything it shouldn't have, but fair point I'll redo the tests in the morning and double check the conductors are well away from anything
Hi,
I've just been testing a ring final before installing an outdoor socket and I got an R1 and rn of 0.6, but instead of 1.01 for R2 I got a range of readings from 0.1 to 0.51 and it wouldn't settle down, so I couldn't continue the tests.
I know parallel paths could cause a low reading, but...
I've never heard of niglon before, but from a lot of pictures I've seen, the main switch is either in the middle or on the left, this one has two, the one on the right, the other is behind my arm in the middle. I'm really baffled as to what's gone on here. I dread to think what I'll find when I...
Just got called to quote for a new job, and as part of doing so I asked to check the board. This is a Niglon board, fitted by a sparky about 18 months ago. Answers on a postcard if you can spot an issue!! Bonus point if you can guess the four letter word I muttered.
The back boxes were all dry, so I'm not suspecting a water leak. Cables were all renewed in roughly 2012 (That's the date on the consumer unit). My suspicion is that the fronts were put back on before the plaster dried (There were plaster splashes on the back of the front plates), thus it was...
Hi,
I've just completed some fault finding on a ring final, as I couldn't get continuity on the CPC, and I found most of the metal back boxes and CPC conductors were in a pretty bad state with lots of corrosion. I did a bit of cleaning up to get bare copper, and it worked enough to get...
Unfortunately to answer the question about not isolating the whole board, there is only one ring for the whole house. In other cases I've been lucky that either the house is empty or the fridges etc have been on their own circuit
Hi,
Does anyone provide backup power for when having to turn off power to an occupied house for long periods of time ?
I've got to turn off the power to a house next week to trace a ring final fault and it's likely to take all day and the house will be occupied with a young family so they will...
I managed to sort it out by installing one of these quick connect light connector boxes. They are really for quickly fitting downlights, but they worked a treat for this, and fitting nicely in the housing.
For some reason I'm getting the strange and unusual faults at the moment.
Got called a day or so ago to a tripping RCD. House is quite old and has a modern extension, so there were two consumer units. The fault appeared to be in the older board (I say older it was a board from 2015ish). Anyway...
Been trying to find an answer to this one, but haven't found a definitive answer.
Long story short, I have a Class II metal wall light fitting which for various reasons it's now a Class I (I've had to modify it to make it work due the stupidly supplied cable being way to short and the lighting...
Just seen an image of a damaged cable and the body of a mouse, and it's made me remember a throw away comment from the tenant that they've had mouse issues. Just shows how important it is to listen to the occupier as well as doing the inspection. I admit that just didn't register with me.
I can...
Here's one I wasn't expecting on an EICR. Recently rewired and renovated 2-bed property (2015ish). Having an EICR as a new tenant to move in soon. No reported problems.
I expected to be in and out in about 3-4 hours to be honest, and as expected I found nothing wrong until I began my ring final...
Gone with a 2006 Honda CR-V, 95k miles, 12 Months MOT, no advisories, fully serviced at a knats over £3k. One of the last to have a side opening rear door. I'll retrofit roof rails later.
