Hi I have a 22mm copper pipe running from the meter under the floor which branches off into a 15mm feed for the front room gas fire. Still in 22mm it continues and branches off to feed the hob in 15mm and then on to the boiler also in 15mm. I plan to resite the boiler and need to branch...

Hi I hope someone out there can give me a definitive answer. I need to install an extractor fan in Zone 1 above the shower cubicle but because I have a low ceiling the fan could be within reach of a tall person using the shower. I know that using a SELV 12V fan will do the job but my...

Thanks for your help......

Hi all I have one of these fitted in a new build, can you please tell me what qualifications should I be looking for in the engineer when getting it serviced every year. I understand I should be looking for an engineer with a 'ticket' for unvented systems. Could you please explain what this...

Hi Does anyone know why the Italians use Type C MCbs in a domestic environment. Was over there recently and noticed that in a domestic environment they all use double pole type C's. Just curious....thanks

Thanks boys, thats what I thought they were. I will probably be using them to connect the fglex from the water feature on the patio to the IP56 adaptable box where the SWA terminates. Can anyone recommend a suitable flexcable 1.5mm to use for this that is UV resistant and conforms to regs...

Hi I've heard the term Stuffing Gland which I believe is used for non armoured cable. Could someone please explain where these glands would be used, are they waterproof and how are they assembled say in an IP56 box for use outside. Do they differ from PVC glands in any way? Pics would...

Thanks everyone for your input. It looks like I'll export the PME using 6 mm SWA on a 20a fuse with the potentiall to increase this to 32A if needed later. The LABC are already involved with an ongoing side extension so I will use this notification to check out/approve the garage circuit.

Thanks Spark123, am I reading this article correctly: If the garage does not have an extraneous conductive part (which it does not) its just a bare garage with a concrete floor, then its OK to export the earth on a PME supply. If the garage does have an extraneous part eg. a water pipe...

Thanks for the above, but its still not clear to me if I need to export the PME earth or not., and exactly what earth connections are made at each end.

Hi I need to run a supply to the garage at the end of the garden, approximately 30 meters from the house. The load on the garage will be just a tumble dryer and a light and there is no water supply in the garage. The main building supply is PME and theres is no spare ways in the CU. The...

Just had a thought, as there is limited room in the adaptable box could I get away with just connecting the banjo to earth at the other end of the cable?.. The steel armour would then still be earthed or is this not good practice? .thanks

Thank you all for your help, very usefull. Just one query, am I right in saying that if using 1.5mm 3 core SWA and terminating in the IP65 or IP68 adaptable box do I still need to use the banjo and connect the armour to earth? Or can I discard the banjo and use the earth in the cable...

Luminaire The concrete is alredy laid, would laying the cable under the slabs and channeled into the patio not be acceptable with somekind of indication that cables lay underneath. I really do not want to dig the patio up. Any ideas?

Gents Missus wants lights on the patio of the type that stand upright. I am not a practising spark but many years back I did do my C & G Part1 & 2 and also the Inspection and Testing qualification. As a non practising I am a little out of date with current practises...not to mention the Part P...

Hi I have a Creda dryer, drum rotates all seems to work fine but will not heat the air. Does anyone know what could be the problem. I've done a continuity test on the heating elements and that checks out ok. Thanks Julian

Hi I hope you can help me with a problem and suggest a solution. I live in a flat the CH/HW system is open vented with the cold water tank (about 15gallons, fairly small) directly above the hot water cylinder which is of standard size, both are in the airing cupboard. The cold...
