    Shepherds Hut, which regs?

    We have been asked to install electrics in a Shepherds Hut. Just looking for consensus of opinion as to which part of the regs applies. I am leaning towards a "Park Home" which is not a Special Installation I believe. There are parts of section 7 which could also be applied, caravan, mobile home...

    Led strip lighting issues

    Just read "not switched active". The snubber should still deal with the problem.

    Led strip lighting issues

    What I have found is that when the fan is wired in 3 core and earth the permanent live induces a small voltage on the switched live this "charges up" the led which when the voltage is high enough makes the LED flash. I think it is this discharge that has just enough power to kick - in the timer...

    LED Lamps and extractor fan problems..

    I was just searching for a resolution to a similar problem. Changed some filament lamps in a Bathroom yesterday to LED. Customer messaged this morning to say the fan has been running all night and keeping her awake. I am going back today to fit a "snubber" across the feed and switch line. Same...

    Dual rcd board

    Hi Mike, I would be interested in your view on the type A type AC RCD situation. NICEIC seem reluctant to comment. NAPIT say potentially dangerous (in the main). What do you think please ? There can't be many places with just resistive loads and no electronics (for DC interference).

    Dual rcd board

    Lets see if we get a picture of the CU and RCD. I would agree best route new CU with future proofing for AFDD

    Dual rcd board

    You are supposed to seek the Manufacturer's advice because the Board will be type tested with what it was originally supplied with. I realise I didn't directly answer your question the first time. Are you aware of the potential dangers from type AC RCDs ? Chances are the original fitted RCD is...

    Dual rcd board

    Perhaps more importantly, is it a type AC RCD you would be adding ? Could possibly be wasting your time and money. Why ? because when subjected to DC from electronics they may fail to work, not worth taking a chance.

    Tunstall Piper Haven Speech Unit

    I know this is a very old post but I have a similar problem. Apparently it could be the smoke chamber needs cleaning. The one I've got has relays to link to the Tunstall system. My fix, new Aico alarm with relay base.

    UK Why does my RCD keep tripping?

    I would still consider informing DNO. Had a similar "call-out" last weekend. Neutral burnt out in joint outside the property. IT COULD ALSO BE A BAD CONNECTION INSIDE THE PROPERTY, RISK OF FIRE, GET IT TESTED QUICK !!

    UK Why does my RCD keep tripping?

    Is your property served by an overhead line (T-T Supply) ? If yes, sounds like a possible loose connection on the supply side. I suggest that you call the DNO (District Network Operator), they own the cables . The higher current demand will cause the (possible) loose connection to drop voltage...

    Bonding extraneous parts

    To be an extraneous conductive part the metalwork has to be capable of introducing a potential into the Building. Unless the hand rail is connected in some way to structural steelwork of similar this is unlikely. We then call it isolated unearthed metalwork. Check the regs. there is a specific...

    Consumer Unit I would be interested in your sage comments

    Good point but the fire alarm etc. not a lot of use if you are out at the time !! 1583962281 Hi Mike, I was thinking that in the future insurance cover for electronic equipment may be dependent on having SPD.

    Consumer Unit I would be interested in your sage comments
