    Ring wired in 2.5mm and 4mm

    Being trying to sort out the sockets at a house this morning. A right mess, spurs off spurs everywhere. I have identified the ring itself and how it runs, but it seems it is partly wired in 2.5mm and partly in 4mm, seemingly at random. I know it's electrically sound, tested it and it's fine...

    4mm Radial vs 2.5mm Ring

    Hi all, when undertaking a full rewire I have always installed a 2.5mm Ring Main for the sockets. I am considering switching to a 4mm Radial for easier testing (plus I don't like the idea of it being possible to unknowingly break a ring main and not know about it causing possible overloading)...

    Easiest way to protect 2.5mm spur off 32amp ring.

    Found a 2.5mm spur running of a ring (no rcd, 32 amp rewireable ). The spur supplies a outhouse with a CU (10amp and 5amp mcb) Due to layout cant get take spur directly from closer to the CU, or put in a separate circuit. Simplest seems to be to put in a 13amp fcu to protect the spur, however...

    What load can this 2.5mm T&E take???

    As above, I have a plumber who's changed the water heater on a finished garage annex that we've been doing. The original one was 1.2kw in a bathroom undersink unit. There is an electric rointe 750w towel rail aswell so I put the two on the same circuit to save ways in the new board. He now wants...

    1mm cpc in 2.5mm T&E

    Hi guys. When and for how long was 2.5mm T&E produced with a 1mm CPC? And why?? I'm at a house which uses this stuff (all with white sheath) all over the place. One ring circuit uses this for one leg but 2.5 with 1.5 for other leg.

    The integrity of 2.5mm "flex" vs. Twin & Earth

    Is there any rule, as per the regs, that states that flexible cable can or should not be joined with T&E for the purposes of extending? When I say "flex" of course I mean the stuff that you can twist the cores with your fingers vs T&E, which is a lot tougher and requires a tool, but is still...

    Current carrying capacity of 2.5mm flexible cable

    Hi Guys if anyone has a regs book to hand please can you give me the current carrying capacity of 2.5mm flexible cable clipped direct, single phase.

    Can 2.5mm flex ever be wired to a socket?

    As per the title, really. When I say socket, I don't mean on a ring, I mean on the end of a flying lead.

    Does a 3kw immersion heater demand 2.5mm cable?

    And if so, if a 30A relay is being used to switch power to the element, does the supply to the relay need to be 2.5mm as well?

    2.5mm earthing conductor from TN-S supply

    I found a nice easy second job for my Elecsa assessment. A mate wants an outside light fitting in his porch. He had a new consumer unit fitted last year, all circuits are RCBO protected, and he had a load of other work done at the same time. He's also had some other minor work done since then by...

    Joining 10mm to 2.5mm T+E

    Another joining cable thread..... Just curious how you chaps would have done this ? 10mm ---> 2.5mm T+E, adaptable box will be permanently accessible after (re-using old shower supply) Sy:smug2:

    2.5mm on 12V running warm - normal?

    I installed a replacement 300VA transformer, fitting a 2.5mm from secondary to junction box where it splits out, feeding 5 x 50w halogens. Cable run between the transformer and junction box is less than 18 inches. The casing of the transformer indicates 2.5mm - you'd struggle to get anything...

    6mm becomes 2.5mm

    Old fine stranded cable size 2.5mm or 4mm?

    A while go i was asked to take a look at some sockets at the owner believed he had no CPCs in any of them (he did). The house was pretty old 1920s-30s. The cable was in in old red/black colours, outer diameter was larger than standard solid core 2.5/1.5mm but i would say smaller than 4mm, but...

    2.5mm ring with 40amp cb quandry

    Hello All Recently did a pir and found a 2 ring circuits wired through a 40amp c/b one in 4.0mm and one in 2.5mm I feel that the 4.0 mm is acceptable and tradition would say that 2.5 is wrong but thinking about it if a 2.5 has a cuurent capacity of 24amps then on a ring circuit with half the...

    Conduit for 2.5mm T&E Ring main

    Hi all, I am currently fixing up a room in my house and after removing some built in bookshelves found that that wiring for the single socket in the room was surface mounted on the walls. Given I'm doing a fair amount of plastering in the room I would like to re-route the wires through my loft...
