Spark123, so far as I know there wasn't, though its possible a pesky householder plugged something in upstairs while my back was turned. Surely any load would tend to make the RCD more likely to trip rather than take longer though? Gavin

Testing a newly installed Crabtree RCD today, and it passed all tests except the 5x at 0 Deg (12ms at 180DEG). It did trip at 0 Deg, but not within 40ms. (it is performing supplementary protection so test is required) Apart from a duff RCD, am I missing anything obvious that could also...

Streetlighter is right I'm afraid shedhead, you can play with the figures yourself here I should have thought you could get away with a lower rated shower, 5kw or less should let you use 6mm SWA (much better than standard pvc cable even through a conduit). Just thinking out of the box a...

Panny, Could be a number of things, but assuming noones tapped a nail into a wall recently the most likely, in no particular order are: Rodent nibbling a cable somewhere (mice in the loft?) Heat damage to a cable where it runs too close to a heat source such as down lighter or boiler...

Sensible advice from nozspark and a periodic first is a good way to detect any serious problems. However, if you did change the cu and found problems during the testing then they would not automatically have to be corrected, depending on what they are. You do not have to bring old wiring up...

ethans, There will be an earth terminal, though I can't advise where it will be. If the connections are made to the RCD part then that may only have Live and Neutral connections, but the back of the socket will have an earth - it may be that there is a cover over it that has to be taken off...

Kev, Yes it is perfectly acceptable to run multiple sockets on one 2.5mm2 cable 'downstream' of a FCU with 13A fuse - the FCU is the protection against overloading the cable. Alternatively if the cable is only feeding the conservatory you could run a single cable as a radial circuit with...

Moody, This may do what you want: Russell Hobbs 10994 Edit: May be better stock here Gavin

As Davy says, Part P regs do not allow an electrician to sign off another's work as their own. However, if they can get access to the cabling to test, etc. you may find one willing to do it (assuming it has been done correctly of course!). Your other alternative is to involve Building...

The one I saw worked purely as a switch in the lighting circuits. So the lights had to be turned on during the day, and the unit set to DAY mode. Then the lights were normally off, but flashed when the doorbell was pressed. There was also a NIGHT mode on the unit, which I didn't investigate, but...

I ran across one of these recently, that had been installed by the RNID. It was basically an electronic switch that was wired between the lighting circuits and the mcbs. What you will probably need to do is identify which circuit/circuits are feeding the lighting circuit and then connect...

sorry but I'm not a registered wee-er :) Yes, it passed the ramp test, just the 5I that it wouldn't do due to the earth. I guess its something I will have to bear in mind for future reference, since there are quite a lot of TT around here, even though we are supposedly urban. I will use...

I realise that the earth is not ideal, but it could still be seen as compliant, and I would argue therefore 'adequate'. The reading I took for Ze was just under 200 Ohm, although the fact that my Megger wouldn't test suggests that it considered it higher at the time of test. In fact in this...

Whilst adding a small CU to a job today (to stop the garden lighting tripping the whole house) I ran into an issue with testing the rcd. The Ze of the house (TT installation - quite a lot of them round here) was rather high at 200 Ohm but since the main CU had a 30ma main incomer could be...

If the third cable is connected to the same mcb as a ring then to comply it can ONLY be serving a single 'point' (single, double or FCU) - otherwise I would say that it needed a separate MCB. I read it that the single cable was only serving one point, in which case a spur is allowed to be...

I'm in Kent and had a similar notice a while back from EDF (I think they are the DNO in Essex too?) Apart from not turning up on the first date I gave :evil: they also said they couldn't fit an isolator and that I should contact an electrician. The guy who came out to do it took about 20...

Hi Dan, As someone who did the EAL course last year, and is now just starting to tip my toe in the water and do jobs, I can offer the following based on my experience. The course is intensive, but mostly about the regulatory side of the business. In fact our instructor deliberately made...

Hi, While you probably could extend the ring main, its not the way you want to do it, especially with a large garden. The main things to think about in a garden are weather protection and rcd protection. The best option is likely to be to run a new circuit from your consumer unit to...

yep, well the job is an old dear who likes it, so I will check it out and see if I think its safe - in which case she's the one who has to look at it every day :) So this is effectively the first generation of 'compact' flour lamp I guess.. How long ago were they on sale in Argos...

Not quite Wesj - The regulations will be published in Jan 2008 in final form but are not due to come into force until June 2008. The draft for public comment is still available here although comments supposedly stopped back in February. Not sure when the final decision will be made but it...
