Hallo Opps, Mine have been in a bit longe than yours, but working perfectly. Don't have the condensation problem (wife puts stats between "Little Boy" and "Sun") and I use Rolls-Royce Trent XWB as extractors ! Only issue I have is splashes turning lights on & off. Now that we've got...

Morning Belly, Like others said, don't even think about it for heating the room. I've got it in two bathrooms to warm the tiles so that it's not too cold for my wife's dainty feet, and dries the floor afterwards (c'mon RF, surely there's space for a little luxury in life ?). Control temp is...

Stoday, how many dp do you need ? Both are the same to 5dp, which is 3 more than the accuracy needed for every day work. Even the best calipers or micrometers (outside of a calibration lab) won't give more than 2dp ! Regards, David Ps I was taught to use 22/7, which is 3.142 to 3dp...

Cheers Martin. I never got round to the live app, but I'm glad someone has. Regards, David

John, Thank you for your kind words. In hindsight, a little less haste and maybe a little less flippancy would have been better. A TT install must be protected by an RCD. Regs could be satisfied by a 100mA time delayed device. Obviously, to protect the whole installation, this should be...

Ricicle, plugwash, Blindingly obvious now that you say it. Hadn't thought it through, thanks for pointing it out. David

Ricicle, why shouldn't I use a metal clad with appropiate bonding ? BAN, SOH gone AWOL ? David

1) Want to be able to repeat the failure ensure it's fixed. 2) fold the tails double and secure with a cable tie. That should keep the electrons in.

Bernard, good point. My plan: 1. Find out if it trips on power off or power on 2. Find out if RCD trips if all MCB's off 3. If not, add MCB's until it does 4. See if it still happens with everything disconnected on this cct 5. If it still happens, investigate this cct 6. PIR on the...

MK just confirmed that all their RCD's are passive. Waiting for Hager & electrium to respond, but I expect the same answer. So, something in the install is causing it to trip. Rocky, good point; I assumed it was as power was cut, but will check whether it goes on power restore. Odds on it...

Thanks everybody, Looks like we're all agreed that the VOELCB must go. But the passive/active RCD issue is unclear to me: Passive = no trip on powerfail Active = opens on powerfail I've checked MI from Hager, MK & Wylex and found no mention of active or passive for rail mount types...

Hallo BAN, I thought you were advocating fitting an active RCD, now I see that you're referring to the one currently fitted. Alle ist klar, as the teutons say. Does this mean that rail mount RCD's are usually active ? My instincts agree with your sentiment about about a complete install...

BAN, I'm a little confused....I thought an active RCD would open on power failure, and was also know as a non latching ? Surely what's needed here is a passive, latching device ? Here's a SO one: http://www.tlc-direct.co.uk/Products/SMTGV204.html Haven't found one suitable for a...

There is a rod, connected to the MET near the VOELCB. Could the "electrician" have been right, and it's a cxonsequence of the VOELCB, but failed to explain it ? My mate didn't say that he'd been quoted to remove it. I can't see a need to retain it - the RCD will suffice as a main sw...

Afternoon all, Got a friend (honest !) who has a problem... He lives in Surrey, a bit in the sticks. Overhead supply, TT, VOELCB and a CU wth a single 30mA RCD. Unsure of age, but all visible cables are PVC. I have seen it, but haven't had any kit or done any delving, so no test or...

Cozycats, not sure I get your point. The CU has a 30mA RCD as main sw (probably installed under 16th regs), but all lights have their own switches, and all SO are switched ? David

Try this http://www.tlc-direct.co.uk/Products/STNM3000B.html I've got one, and it's brilliant. David

Alarm, Waaaay too much...I'm thinking this, if I can get them to fit the horses... http://cgi.ebay.co.uk/19-LED-Ultra-Bright-Headlamp-Headlight-Torch-Waterproof-/320676775588?pt=UK_SportsLeisure_Camping_LightsLanternsTorches&hash=item4aa9d346a4 RF, I'm no great lover of halogen...

Hallo Bernard, Definitely food for though there. My boots are Dickies Riggers, and described as "antistatic", but no DIN or EN or even BS referred to. Maybe they don't allow me to build uo a static charge, but will allow a discharge from something charges above earth (well, concrete floor)...

Hallo Bernard, Both items cat 2, all plastic body & switch case. Vacuum has a plastic earth pin, sander has 2 core flex. No connection to earth rod at all (except via the ground beneath my feet !). I've just had another thought - maybe I became statically charged, which discharged through...
