Hi Guys, wondered if anyone could give me advice on hypothetical question. You go to a customer who wants an additional light added onto a lighting circuit. lets say they want 2 lights in there sitting room instead of one. How would you go about carrying out a Zs test if all the other...

Hi, Is it acceptible to connect the main earthing conductor that is ran from a earth rod on a TT system to the gas pipe on route to the main earthing terminal? The cable is not broken, just a small part of the outer sheath removed. Or would you have to run the main earthing conductor all the...

Hi, can anyone tell me what PIR code you would give for 240v spotlight's in a bathroom with no RCD protection? (done to 16th ed.) None of the spotlights are in zone 1, whom ever installed them placed them just outside the line of the bath. I was thinking of a code 2. but reading up you could...

Hi, could anyone tell me what the short circuit capacity of this main incoming fuse is? It does not state anywhere on it whether it is a S1A, S2A or S3A? Thanks

Hi, I was wondering if anyone could tell me what type of fuse will be fitted inside this Main incoming fuse? Im afraid in only used to the normal black plastic bs1361 type 2 style fuses and this is a lot diferent :) And yes I know the the tails out of this fuse is only 6mm and...

Hi, I have recently had a Baxi duo-tec 28 HE installed. However, when i put the central heating on there is a rubber pipe at the rear of the boiler that starts to leak. this rubber pipe is connected to the top of the filter. Can anybody tell me if this is normal and the rubber pipe should be...

Hi, I have been round my friends house as he has a TT system and I have never worked on these installations before. (yeah yeah, pathetic I am! lol) Whilst doing the PFC the result was 11 Amps. Is this correct for a TT system? I am guessing it is as the Ze was 20.9 ohms. I was just...

Just a quick easy one for clarification :) when measuring the Zs value on a light circuit they normally say measure at the extremity as this is where it will be highest. However, I have a situation where my highest reading is on the second loop in loop out ceiling rose (out of 5). This...

Hi, can i ask for a number of opinions on this small matter :o). why is it that safety zones are ran down each side of the wall and horizontally/ vertically from all sockets? if you are fitting kitchen wall units against a back wall you always fasten the units right in the corner (or at...

Hi, I was wondering if someone can give me some advice, The answer (IMO) is obvious but just wanted to know for certain. I know an old property that is getting rewired and the main incoming fuse is one of these in a old cast iron box and both the live and neutral are both fused. there is also...

Hi there, hopefully one of you wonderful people can help me understand the problem i think i have. I have fitted a mira excel built in shower and i have very little pressure and also the temperature is crap to put it politely. I have read the instruction manual and it says that a mini...

Hi, I am wiring up a hob which has a total current rating of approx 32.5A (7800kw). However, the instructions say use 2.5mm cable, and the connection point is only suited to approx this size. seriously it would be difficult to squeeze 4mm cable in. so i have bought some HO7BN4F 2.5mm cable...

Hi, I have a circuit which is running of a 15A Wylex fuse wire breaker. From the CU it is ran in a radial, single wire leaving fuse box. However when it reaches the converted loft it enters a junction box and then all my sockets are wired as a ring into this junction box? Can this be left as...

Hi, is it feasible to take a spur of a ring main, to a 13A FCU and then from there to a junction box which will then split out 3 sepearte feeds which will power a external security light, a burglar alarm and also a smoke alarm. Many Thanks for any advice

Hi, First of all Is it satisfactory to Spur of a ring main, put a 5 Amp FCU and then run mains from this to both a burglar alarm and a switch to a outside security light? So you would have this:- RING MAIN ----- 5A FCU ------- 2 feeds coming out, one to feed the burglar alarm and then other...

HI, Bit bored at work here so thought id send a little post and hopefully some one will have some good info on what is the best way to overcome routing a new cable to a CU. Scenario:- fitting security lights outside, CU has spare way so thought ideal place to use :) lifts floor boards...

Hi, im not doing this so it is all hypothetical really. If you are testing a TT supply what is the best way to test the earth rod been correctly fitted. Can you do this with a megger 1552 or do you need a separate earth rod tester? do you just test the system as normal for getting your Ze...

Hi, Can anyone tell me if it is satisfactory to drill a hole through a window frame or wall and attach a security light to a plug and use a normal soket on the wall. (very easily done) Or do you have to run the security lights directly from a seperate switch on the wall from a FCU? (quite...

Hi there, sorry for this but i just feel the need to get this out! This site is full of people who think they are capable of doing their own electrics in their own homes, a lot of it is basic and some of it is quite excessive, but they are here to learn and not make the mistakes that obviously...
