Hi Bernard, thanks for the reply. There are no water pipes at all in the roof space, and it hasn't rained for a good few days. It doesn't seem to make a noise during the day, but I will need to confirm this. The only cables which are in the roof space is for the lighting circuit, but again...

Hi Joe, I don't think it is expansion/contraction, as it started at 8pm last night, and is still doing it now at nearly 7am. Could possibly be birds, but there is no light up there? Plus would birds be making the noise all night tapping away? Cheers

Hi Guys, Hoping someone can offer some advice. I live in a top floor flat, which incorporates some sloped ceilings as it is in the roof, and on a night in bed, for the past couple of nights I have notice a tapping sound coming from a specific area in the bedroom, which is near a sloping wooden...

I was looking through some old factory wiring schematics, where I have started a new job, and don't quite understand them (still an apprentice), and the guys here don't have an answer, so I'm hoping someone here might be able to? There is an old ring main ran around most of the building in...

Brilliant. Thank you for your help!!

That looks exactly what I am after, thanks a lot :) Would you normally bond that to the pipe work? Thanks

Hi, Thanks for the replies. Those items in the links would be ideal, but the pipe work isn't used for a soil pipe, its for a spray bar on a cooling tower (laid horizontally). We need to retrofit a hatch to the 'top side' of the pipe, as the under side has nozzles on, so we cannot...

Hi, Is it possible to buy and retro fit a type of inspection hatch for a plastic 5" (may be 4") pipe? I thought they were readily available, but I cannot seem to find them anywhere online. I need the hatch cutout to be big enough to put a hand in to it. Any pointers would be much...

Thanks for the replies. The charger will be outside, so does need a double pole RCD. I can't see anything like that on the schneider site to directly fit in to the board. In terms of availability, will it be best to install a MCB in the DB, then in an adjacent enclosure install a double...

Hi, Thanks for the reply. They are only single phase chargers, so a RCBO should fit straight in? The only problem is finding the Type A. The manufacturer and recommended the Type A over AC due to nuisance trips, so ideally I would like to source a type A RCBO, but cannot seem to find...

Hi, It's a Schneider board. I cannot seem to find any RCBO's to fit though? Are they available, or only available in RCDs rather than RCBOs? So I may have to install a MCB in the DB, then use a seperate box to house the RCD? I'd rather not as it is more work, but I can't seem to find any...

Ok, thanks :) I've not received the charger yet to be honest.

Hi John, Thanks for the reply! Where online can you purchase the Type A RCBO? I can't seem to find any? Thanks

Oh right, I'd read 'special' ones were needed?

Where can you find Type A RCBOs rather than Type AC? Just I want to install a car charger, which has a build in RCD itself, but I believe that will be on the secondary side of the transformer, so obviously I need one from the DB. It needs to be a Merlin Gerin/Schneider/Moeller to fit in...

Lectrician, as when previous fittings has been removed, they are that old the wires are chared, so not safe to re-use them. RF Lighting, it's a small family business which we are all trying to keep above water at the moment, and a lot of the time we DIY! I am putting myself through college to...

No, industrial. A lot of the lights are that old, they need replacing. But the original lights were wired with RYB, B. But obviously the new lights need to use BBG, B when wiring them in to the junction boxes. The best way would be to re-do the whole wiring, but this isn't really...

Thanks for the replies. The installation is a set of lights, with a 1/3 of lights on each phase. So they would need making L1 L2 L3 respectively at each junction box. Where are the stickers mounted in this case? On the junction box lid? Cheers

Can someone confirm please. If mixing new conductor colours, Brown, Black, Grey, Blue, with old conductor colours, Red, Yellow, Blue, Black, It says in Appendix 7, Page 407 of the book I have that: "unambigous identification is required at the interface. Cores should be marked as follows"...

Thanks for all the replies guys. I can see where Ban-all-sheds is coming from, but I do a lot of research on the internet rather than go to the library (different generation perhaps?), and generally asking questions doesn't always give me the answer, but a lot of people, especially on here...
