    Install in Server room and ac unit

    No there's no false floor, the servers will be at one side of the room and the ac unit will be on the other side. Nobody works within or near the room, it's a locked room. It's only purpose is for the server. As for leaks I'd imagine the caretaker of the building will do some inspection whilst...

    Install in Server room and ac unit

    Cheers for the quick response guys, There will be 1 server tower with a monitor. There is a ups system going in. Instalation method is clipped direct, it'll run above the ceiling tiles until I enter the server room where I'll use conduit to drop down to each socket outlet, the entire run is...

    Install in Server room and ac unit

    Evening guy, just wondering if I could get a bit of clarity...... I've been asked to to install some sockets into a new server room and spur off to feed a wall mounted aircon unit. My thoughts for this would be to install a new circuit and keep it separate from anything else to avoid unwanted...

    Led flood lights failure

    Cheers for the reply.. A "bodge job" is definitely not my intention, I generally love what I do and pride myself on neatness and reliability. The point about the sy in uv light is actually a brilliant point, I'll definitely take that on board and anything outdoors from now on I'll just use swa...

    Led flood lights failure

    Yes there working now. As for the wrong cable and wrong glands, I got taught that each job is designed to its surroundings aswel as it's use, and the lights are completely out the way, and there's no possibility of damage therefore I didn't feel the need to over engineer it, the only reason...

    Led flood lights failure

    Hi sorry for the late reply, for some reason I've received no notification emails. Anyway the lights are 30w led tamlite, and 3 out of 9 failed. I've used ip66 boxes to connect the flex from the lights and also the next light down ect.. I've used sy 3 core because it's cheaper that swa and...

    Led flood lights failure

    I did, I checked the rest and they were fine, I'm even considering changing the wiring tomorrow including going to a new weatherproof box and then taking individual legs to each light, I'll obviously keep know more tomorrow when I get up there but this will be the third time on the roof...

    Led flood lights failure

    Evening chaps, A few months ago I installed 6 x 30w led flood lights around a commercial building, I wired them in series from a ip66 box with a night and day sensor and a contactor, I went to each light via a smaller ip66 box in 2.5 sy cable, everything tested OK so off I went. I received a...

    Rcbo and rcd in series

    OK I think I'll go with separating it from the main tt, and creating its own tt and protect it from the submain, think this will be the easier option and prevent any inadvertent tripping. Cheers for the replys

    Rcbo and rcd in series

    There will be further decking and a longer run, I measured the garden at 89meters but I'll be ending the run at a out door socket at 65, just future proofed it, and yes there will be a socket but not prior to the board, it will be at the end.

    Rcbo and rcd in series

    No there's no socket prior to the sub c/u and sorry the size of the cable is 4/2.5 lol fat fingers on a small phone, the length of the run in its entirety is 65 meters, I'm also aware the time delayed rcd tripping if not double poled, and in response, it's not, it's an old moeller board, this is...

    Rcbo and rcd in series

    It's a tt earthing system, I know I don't have to make a separate tt system at the submain, just wondering is the rcbo will be enough for the circuits on the submain aswell as the submain it's self

    Rcbo and rcd in series

    Good evening, it's been a while since I've posted on here but I'm looking for a little advice. I'm doing a job this week, it's a tt supply and I'm bringing a sub main to an out building sub c/u which will supply lights sockets, and also a leg that will run to the end of the garden to a decking...

    Electric shower

    Yes I did ask for your opinions good or bad I would like to hear them, it's only going to make me better at what I do, I would like to consider my self as an engineer yes, 4 year apprenticeship and 5 years as an electrician and hnc under my belt so I'd like to think so at least

    Electric shower

    Cheers for the replys, yes I am confident and going off the installation method and time/current characteristics in bs7671 I can't see there being a problem, but there's always that little problem where you second guess yourself especially on this occasion, it's the first time I've every...

    Electric shower

    Both, with details of length of both cables, to be honest I'm pretty confident with the installation and the way I left it, I was just wondering on what your thoughts were towards this, in any other circumstance I would have installed 10mm to the shower the run wasn't accessible at all

    Electric shower

    An update on this job. I've since been back and pulled a 10mm cable from c/u to the pull cord and I've changed the circuit braker to a 40amp type b, however the load side of the pull cord to the shower is still in 6mm, it would have been extremely difficult to change the cable due to tiling and...
