    Which cable in light switch actually goes in common??

    Some brands use C and others L1 as the labelling for the permanent connection. If your permanent live, normally brown, is in this position and the switch is the right way up then the off position is always off so I'm not sure what you mean- off is when the top of the switch is pushed in- push...

    Conversion to TNCS within property. A concern? And EICR code?

    Are they sheathed? If that's just insulated cable then C2 for that anyway.

    EICR today Mains smoke detectors interlinked

    Op, do you mean there are Aico hard wired and interlinked smoke alarms in a house that is now two flats, and then a few doors down the street with neighbours in between, there is another house converted into flats with smoke alarms on the same circuit? And you do not know what house even powers...

    Earthing system quiz

    So what did they do, just link the earth terminal to neutral in the cut out?

    Keep getting electric shocks in kitchen.

    Wearing shoes or not you shouldn't be getting shocks from metalwork in your house! What are you getting shocks from? Sockets, switches, sink, taps, radiators?

    2365 lvl 2&3 is it worth it?

    The 2365 level 2&3 are the technical certificates- with them you can take the am2 and complete the nvq which will then give you the equivalent quals as a time served apprentice. Also with all of the above you can register with one of the schemes. If you have the level 2&3 and the 2391-52...

    UK Eicr codes for rented properties?

    I agree with above, no change to codings, whatever you would normally give still stands - you're still inspecting the installation based on the requirements of and compliance with BS7671 and essentially whether or not it is dangerous. Just out of interest, why would you think the coding would...

    What type of light bulb is this?

    I didn't think of that.

    What type of light bulb is this?

    Also looking at your existing bulb it appears to have live and neutral connections exposed so power off before before you touch it- I've seen reports of people getting shocks from badly made led bulbs that have live parts exposed

    What type of light bulb is this?

    It's just an led version, looks like it'll be a G9 fitting. If it is it will just pull out and have two oval pins like the image below: If you try gently and it doesn't pull out it will either be small screw in so twist anti-clockwise or bayonet- push in and slight twist anti-clockwise.

    Official light wiring rules?

    It's a radial so you can branch off at any point as many times as you like. Your main two limits will be design current (so less than 6A or 10A depending on ocpd) and volt drop.

    Any advice on rewires?

    Depending on the strength and condition of the existing mortar, you can sometimes get a good fix with clout nails (the thicker 3. something mm ones). Saves on drilling and plugging- not sure what wall dog is by the way

    Any advice on rewires?

    They do, but need to perfectly straight as you feed them in- 25mm is just easier for 2x2.5mm and needed for 6 or 10mm

    UK Power to shed

    A spur only applies to a ring final circuit and yes you cannot spur from an unfused spur- but in this case, the spur is a fused connection unit and you can branch off as many times as you like without overloading the cable due to the 13A fuse. If it was a radial circuit, then the concept of a...

    Any advice on rewires?

    So much quicker and easier than capping ?

    Help me work out volt drop please....

    So it's asking for maximum permissable v.d and its single phase so 5% of 230v = y (This is the total v.d you are allowed). You are told that a circuit from DB3 has a v.d of 5v so y - 5v = max v.d allowed for the distribution circuit.

    Any advice on rewires?

    Rather than employ someone could you pay for a mate from an agency for 2-3 days? Just to get the cables run in as that's always the tricky part on your own- up and down stairs a hundred times and them in and out the loft for the lights! Don't know how expensive it would be or even if you can get...

    Radial Circuit Cable Length

    OP- is it conduit or plastic mini trunking? Haven't looked at the tables so not sure if it makes a difference to derating factor

    Radial Circuit Cable Length

    That will be interesting. I would be surprised if the total load on the circuit (and therefore assumed design current) was anywhere near high enough to exceed max volt drop requirements. Also how sure are you on the length of circuit? A quick calc shows that even if the design current was 32A...
