AAAhhh this picture makes it clearer, its one of those "Pointless boxes" often used around the 1980's to make unknowing customes feel there getting more equiment for there electriciy bill..lol

Its definatley ok to run you gas bonding from the main earth terminal.

i would use the three core swa for L,N & E and use glands to pick up the armourings as well, i've been trying to find a document i read on hot tubs someone mentioned using the armourings as a second earth, but cant find it and i dont remember why they suggested it, as long as the circuit is rcd...

for VD you need to refer to table 6D2 in the 17th editon it will depend on your cable size for refernce method C,F (clipped direct,on tray of free to air) the common values for guidance are 1.0 44mV/A/m 1.5 29mV/A/m 2.5 18mV/A/m 4.0 11mV/A/m as for cable calcs, havent got my red...

Good advice, then if the all knowlegable customer feels that your tellin professional porkys she can take your report to someone more godlike than yourself for a second opinion, but i have always found in the past if you present them with a nice shiny certificate filled with such words as...

Hi cookiemonsta, you really need to be looking at installting a new circuit for your shed and stables, even pushing the regs and safety to one side for a moment if your outside socket is on a swiched fuse spur on the inside of the house you'd be running your shed and stables on a 13a fuse, a...

have a look for any neon signs on a local chip shop or pub, it may not be lit but still being turned on every night

i must admit i noticed the same when i bought the megaman dimmable gu10's they are very slow. after a little sampling with different dimmers for the amount of lamps i needed to drive they worked out great and save the customer plenty.

http://www.tlc-direct.co.uk/Products/LASD20BC.html?utm_source=froogle Hi ericmark, there are quite a few about that work on stadard dimmers, i understand what your saying about the flicker rate on some lamps being altered to dim them, these ones i've shown above are ok.

i like your thinking ...lol if thats the case im getting em to downgrade my meter.

sorry missed off the first question. clipped direct would be for example a clipped cable accross a joist in the roof or down a wall, not inside a wall. but i can see your point about free in air as this would suggest hanging a cable between two locations not supported by anything i.e between...

the difference between magnetic and non magnetic armoured is the armourings, non magnetic is aluminium and magnetic is steel. Aluminium Wire Armour (AWA) is used in single core cable because it is non-magnetic. When an electric current passes through a cable it produces a magnetic field (the...

Hi Peter, firstly you do understand that under Part P regulations the work you are about to undertake will all be notifiable as it is a new circuit. as for the mixing of colours, you really should replace the legs down to the CU, as this will be a new ring, by leaving in the old legs you will...

Sorry RF lighting, it was a proteus RCD.

i know, i've sent a message to the robin tech guys to see if they have come accross this before, my dads a 40 year time served sparky and he has no answers either. replaced it with a new one again yesterday and its tested out fine, so did all the other flats so why just those 2 rcd's ???? i...
