I've started boarding out my loft and I have a question about some cross battens and their purpose. Photo 1 - Where the roof rafters meet the ceiling joist there is a batten running the full width of the house. This looks to be fastened at each side with wall straps and is nailed to every...

What Salus system would you suggest? I guess there is that possibility when it comes to my lounge and dining room. The rest of the house consists of TRVs which tend to be set low anyway, or radiators without TRVs (for example towel rails in the bathrooms) which I'm happy to run all the time...

Following discussion on this thread, I'm looking to buy either a Hive or Tado system. The system will be connected to my existing Glow Worm Ultimate 30C boiler. https://www.diynot.com/diy/threads/single-zone-two-thermostats.558348/ Whichever system I get, I initially want a wireless thermostat...

I guess that's true - the main issue with having a single thermostat in the office is I don't need this heated in the evenings or at the weekend - which is why I essentially just want something in the office that can be programmed for office hours to trigger the boiler when the rest of the house...

My system comprises of a Glow Worm Ultimate 30C boiler with a Climapro2 RF Thermostat. The central heating is all on a single zone including an office extension - despite being newer the office doesn't seem to heat up as quickly, or retain heat as well as the rest of the house. Ideally I'd...

Definitely not familiar with it :) Is that a similar kind of cable to the DNO feed that comes into the home? In what scenarios would it be used to feed a consumer unit rather than a set of "standard" tails?

Is that a neutral tail made up of loads of individually twisted cores?

The Test button doesn't do anything :D I know that in itself isn't necessarily conclusive proof that it's faulty - I would have tested it but I didn't have my test equipment with me the other day as I'd only called round to do some work in the garden! The more concerning issue though is that...

The Sector 606502 looks a more modern design to me - but it might fit I guess! The existing is marked Vynckier 097/14828-038 - I'm a bit confused by the 038 as all the others I can find online are either 030 or 100 corresponding with the leakage current - but it's definitely an 8 on the...

I need to replace a faulty RCD at my brothers house. The consumer unit is a Vynckier, which I'd never heard of before, but shares MCBs and RCDs with the GE Series E. The faulty RCD is an 80A 30mA however I've only been able to find 63A 30mA or 80A 100mA variants on eBay. The house is currently...

Ah yes, thanks. So sounds like I ought to fuse down - if we assume a derating factor of 0.78 that only gives me 12.48A so I'd need to fuse down to 10A. In the spirit of being over-cautious I think I might just connect the new socket to the load side of the existing 3A FCU until such a time as I...

I don't think any derating factors will apply but just to confirm - the cable route won't be subject to anything other than ambient British temperatures - the cable isn't grouped with any other cables - the cable is clipped direct on the wall at either end and runs under an uninsulated suspended...

Thanks. I stripped a short length of 1.0mm² and 1.5mm² to check my caliper and they measured at 1.14mm and 1.36mm respectively - not quite perfect but certainly within the realms of an uncalibrated "domestic" caliper! All three cables in the existing FCU measured between 1.20 and 1.24 when I...

So I've disconnected the existing FCU off and I'm fairly sure the cable is only 1.0mm and not 1.5mm - it looks somewhere between the two and, having measured it with a caliper it measures between the two, but I'd rather take the pessimistic view that it's 1.0mm. It's not practical for me to...

Another vote for this one. I had a buying spree of pull switches a few years ago when I was in search of a quiet one and these are definitely the best I've encountered.

My garage contains a radial socket circuit, wired with 2.5mm T&E and protected by a 16A MCB. This circuit also feeds a 3A FCU which powers my burglar alarm. I need a mains socket near this and there's no other practical way of getting a new cable to it without removing a tiled floor, so I'm...

At one end of the run the cable will have to pass vertically through the loft insulation - so for a length of 20cm of so - would that class as "through" insulation or is it insignificant enough to ignore? Given I need to re-route the cable, wouldn't it make more sense to replace it with a 10mm...

I'm looking to buy a ferrule crimper. I've noticed that these seem to come in two variants - ones with 4 jaws which crimp in a square and ones with 6 which crimp a hexagon. To my mind, the hexagon feels like a better option however I notice that both the cheap brands on Amazon / eBay and also...

The existing cable is a 6mm.

That's certainly interesting and not something I'd considered!
