    Radial vs Ring in a standard 3 bed

    To all who worship ring mains, why? they are good for maybe doing a domestic kitchen maybe? they are much worse than any radial circuit because of a few reasons 1) breakers MCBs/RCBOs dont cope well with 2 copper cores being just as tight as one another. 2) you have a fault you still have power...

    What Reg would you like to see added to BS7671? and what should be removed?

    All CUs should be made to fit a full rail of RCBOs because when that reg comes in to put RCBOs on every circuit its gonna get Tight.....

    RCBO keeps tripping - without explanation

    I find more rcbos FAILING to trip than faulty tripping without cause, purely due to the way they are made.

    Does a TT Earth 0.13Ohms require a 100mA incomer?

    I agree, have a look for some commons signs like overhead supply and such like, if you cannot find the rod for the Ra then maybe like people have said its now a TN system. From my experience with DNO theyre not always right :-z

    Heres one how about the hoover IS faulty and another bit of equipment and the other rcbos are not functioning correctly ive came across quite a few rcbos that dont work properly and have been sent back to MF.

    2391

    They dont do the 2391 anymore, i believe city and guilds dont issue them anymore, so hence no course to take.

    underground lighting cables

    its cast straight into concrete

    Would this be acceptable?

    just ask your gaffer if the Zs will still be ok at the end of the circuit, hopefully a light bulb will switch on in his head and he will re think it.

    underground lighting cables

    Obviously that scenario would be MORE accessible im just asking if its STILL classed as accessible? also is there a better kind of inspection box OTHER than an earth rod pit?

    underground lighting cables

    Is putting the box with the fuse and everything in just under the flagstone still classed as accessible if the fuse blows, or will i nee to put it all in some kind of inspection pit like an earth rod pit?

    underground lighting cables

    yeah i was thinking that, but was thinking the metal box would provide mechanical protection also, is it ok to put the fused live under the flag just like that then?

    underground lighting cables

    hi just some quick advice please guys, im working on a lampost circuit and the lamposts have been half buried so the inspection cover is underground, ive dug around one removed the cover and there is no fuse for the light, can I terminate the SWA cables in a steel box and put a IP68 plastic box...

    Things an Electrician would never say

    Dont worry about us love, me and plasterers get along just great!

    Down lights install to lighting with no earth

    I dont see the problem really, stick in a cpc regardless. Because A: anything happens or they want something changing most of the time you will be first one back. B: i know guys on here will follow the regs by the book but regs do change and chances are at some point it will be necessary anyway...
