    Proximity to overhead lines?

    I've been asked to install some lighting around an outside menage (horse paddock thing). The client wants metal halide floods on top of scaffold poles. The problem is the supply to the house and small industrial units next door run right across the middle of the menage on telegraph poles (33kv?)...

    Advice needed on consolidating av and coax cabling alongside five 240 volt main lines

    Hi, I need to rewire our Sky Box and CCTV System and I wish to use the existing conduit which currently houses five 240 volt main lines running for about 30 feet. I'll be hoping to consolidate in this same conduit Ethernet cabling x 2, RJ-11 x 1, AV Cable x 2 and Sky Coax x 2. I am concerned...

    Overhead lines

    Got a call this evening asking if I could repair overhead lines between house and garage, haven't seen it but think it could be about 20 meters. Shouldn't be a problem but where will I get cable, is it something that the wholesalers normally stock?

    Two light switched lines in same cable

    Just a quick clarification, I am thinking of replacing a T&E switch wire with a 3+E switch wire as an easy way to convert a single light switch to a double light switch without ripping out the wall. This would mean that there would be two cores as switched lines, one for each light. I am fairly...

    BGB - Strange lines in the book?

    Has anyone else noticed the strange vertical lines in their book? For example on page 164/165 in the right hand side there are various short vertical lines. These appear to lesser or greater extents on many other pages. Does anyone know what these are for?

    Supermarket petrol stations and rip-off air lines

    Just spent over £75 in Tescos filling up the tank and thought I should check the tyre pressures. Not only does the machine now require 20p pieces to work - it needs lots of em to check all tyres. First 20p ran out after checking the two front tyres - and I wasn't hanging about either. Morrisons...

    Do 2-phase (split phase) lines ALWAYS need to be switched together?

    Here’s the scenario: 240/480V split phase, rural overhead, ‘Farm’ supply. From the main house Hager DB, two ways are used to supply 50A, both phases, on 16mm2, to a sub main DB in the workshop. Is it OK to use two separate 50A Type C MCBs in the DB (cheap and available) rather than a...

    Non-standard lighting cabling: single neutral plus multiple switch lines - is it OK?

    I’m upgrading some lighting circuits to a programmable ‘Futronix’ system (similar to Lutron). The 16 x 5A channels Futronix panel is fed from a single-phase 40A 30mA RCBO. It’s in a listed timber-frame building with very difficult cable runs. I need to transfer the switching of four lighting...
