Ha Ha i vote for....... GREENSLAW!!!!!! :lol:

No need to be confused Wild.... Has your oven come with its own length of flex already attached? Because if it has then... Yes the ovens wiring will need local protection from a 13amp fuse. I dont know if your running a dedicated circuit to an FCU or your tapping off the kitchen ring/radial...

Lets start with an exact length for the SWA cable,as length will determine volt drop amongst other things. This is some hefty set up your planning and from just a quick glance over it the main supply would be no where near up to it.

doesn't harm for a competent person to double check does it? How many of you `competent` persons out there have to nip to the van to `double check` an MCB`s max Zs value ? Ive seen many a `competent` spark on here asking questions about regs,remember its better to be safe than sorry. :roll:

Wahoooooo We can scrap ohms law :lol: :lol: :lol:

Ah **** you found one of my earlier jobs :roll: :roll: :roll:

Sounds like a loose connection somewhere. Double check your tester to be on the safe side though. My calculations say for a length of 10mm copper is.... At 20 meters 0.04 ohms At 25 meters 0.05 ohms.

My understanding on this is that there isnt a minimum or maximum value to be measured, all that needs to be confirmed is you do have good sound continuity between the MET and your pipe work. In some cases a visual inspection is all that is needed to confirm continuity (as long as you can see...

Hi rorkers... What you really need to do is calculate how much current the original items in the loft are using at the moment and then see if adding the 3000w heater is going to take the circuit above its limits. When you think a 3000w heater will pull approx 13amps alone it doesn't leave...

If the manufacturers of said extractor fan have designed it to be double insulated then there is no need to earth it. On the wiring diagram in the instruction booklet ,or on a sticker usually located inside the casing of the fan, it should state, if it is ,indeed double insulated or there may...

Agree with Davy.... i bid for the Armeg box sinker off Ebay...tried it twice and it was back on Ebay a week later. I,like others use a lump hammer and cold chisel but find my old wood chisels tops for tarting up the edges. SDS hammer drill with chisel bit for the main chasing of recess` in...

Overkill?? Saves carrying lots of sample cables to compare to though,as was mentioned above! Stop bein a tight wad plugwash and spend some of ya millions!!! :lol:

When i come across a cable where i cant see the size and need to be 100% sure,i use a micrometer i bought from screwfix. Item code 36839 £11.49.

Cant see it being long before its a necessity for ALL circuits in an installation to have some sort of RCD protection. As is said by a few regulars on here RCBO`s are the way forward but price is a huge factor in this and lots of consumers out there who dont really grasp the concept of...

Hi rab... When the electricity board came round did they tell you it was a T.T earthing system? If they did then your incomer must be of an RCCB type (as you have now) but your 30mA one will cause nuisance tripping. As Lectrician says tests need to be carried out to see if a fault exists...

Did i get my REG wrong Spark?...doh Tis a good job this question aint from an assessor. :oops:

Ha Ha i like these , i was taught Chris Baen Peef c=cont cpc r= cont ring i= insulation resistance s= seperation of circuits bae= barriers and enclosures n= non conducting locations? p=polarity e=earth electrode e=earth fault loop f= functional

RF ... `IF` the wall in question is 100mm thick OR less then you are 100% right as thats the only instance a safe zone extends to the reverse of said wall. `IF` the wall in question is over 100mm thick then zones on the reverse do not apply and `earthed metal capping` affords protection...

You can use metal capping for cables outside the zones long as ... i) The metal capping is earthed ,where if you screw or nail through the capping (making sound electrical contact with the earthed metal capping) and touch the phase conductor,a direct path is provided for earth current to...

So in that case RF... Your subjecting a cooker circuit to RCD protection and with leaky earth currents on these cookers do you not get false operation of the RCD? I wouldn't have thought labels would be needed on any downstairs sockets for the only reason of that the particular...
