    Competition Time: WIN a MAINSLINK from RF Solutions Ltd

    Shock sensor on roof. PIR detector for area, contact on door and trapdoor. CCTV cameras external. Not foolfproof I`ll admit but quite a bit of security there including the 5 lever mortice lock plus two electro locks on the entry/exit door - work on the basis of "whatever the mind of man can...

    Competition Time: WIN a MAINSLINK from RF Solutions Ltd

    Good Question. My own shed with various tools in adds up to a pretty penny replacement-wise. So a mortice lock and key as standard but two 12v electro door releases too so even if you have the key or can pick the lock you still have the electro-magnet lock to beat from the outside (from the...

    Competition Time: WIN a MAINSLINK from RF Solutions Ltd

    Remote locking/unlocking of premises - I already use for some premises, even the keyholders can not get access without my remote locking permission ( traditional mortice locks for keyholders but electric locks are controlled by me, I can lock or unlock permanently or momentarily as required). It...

    Ring main.

    Do you not think that is part of my cunning plan? 😀😉

    Ring main.

    Some how the good old ring thread has bounced back again. Ring final circuits are often found in homes and a few other properties. Ring mains are not. Ring mains are of two main types. You might find a ring main underground feeding a housing estate from a substation. This reduces voltage drop...

    Well I only joined it in April 2020 so give it time

    Adult apprentice rate of pay

    Back in the day (showing mee age now!) . Historically apprentices need not be paid. The Journeyman or Master taught them their trade. Agreements between employers and unions then often lead to most apprentices actually being paid a small sum. When I left school if you did an apprenticeship you...

    RCD Tripping out

    Seems I`m in error. Looks like I took the Mention of R1 + R2 and assumed a ring wheras it was a radial. Silly me. However, ring or radial, you must completely disconnect to test properly. However if you want to keep the cpc in the earth bar and temporary park the L conductor there too then, so...

    So we are all agreed then?

    Ring main.

    LOL. yes it is a ring final cct not a ring main. You might find a ring main in the street. You might find a ring main at a power station etc (although not really the type you find in the street. A ring final in installtions - domestic or otherwise

    RCD Tripping out

    "on linking out the circuit breaker for the circuit to earth to do the test " Why are you linking the breaker? I advise against it. Remove all conductors for that circuit prior to testing and usually you`ll have 6 conductors on a plain ring or 9 conductors if a spur is at the origin. Then you...

    Ring main.

    Soi disant, Nice diagrams and well put. Yes I like it. Ok the point I was making. With a bridge that makes a ring final become a "fig 8" it means that we tend to lose control of which leg gets more of the current x usage factor. A I said we don`t usually go to great lengths do control this...

    Ring main.

    Afigure of 8 (meaning a bridge somewhere in the ring) means we can not be sure to which extent the current will flow in every scenario of current draw at any particular times . The other meaning for figure of 8 is the test we deliberately do on an unknown circuit to see if such bridges exist...

    Ring main.

    correct. wheras 2,3 or 4 rings on one fuseway is one cct therefore not a C3 or C2 or C1. It is compliant
  15. E

    Ring main.

    C3 means a reg defect. If it`s not a C1 or a C2 then its a C3, but if not a defect it must NOT be coded at all. Incorrect colour coding of conductors is one example of a C3

    Ring main.

    I cant be a C3 because it complies though

    Ring main.

    Well if you could join the 2.5 ring to a 6.0 (or 4.0) radial, so long as it`s substantially half way around the ring then all the usual ring type considerations should pan out adequately. Again not elegant but hey ho. I feel the double triple or quadrouple ring is easier and just as valid as a...

    Landlord EICR's

    Yep indeed, you are not at fault only doing an EICR, it may irk you that the proper procedure is not being followed ref notification (if indeed the remedial work is actually notifiable) but it`s not your fault and at least it "should" be a lot safer then when you did the first EICR so you can...
